                     DECISION GRANTING MOTION TO DISMISS CASE1

       On January 27, 2014, Christina E. Pope, on behalf of her son, B.P., filed a petition
seeking compensation under the National Vaccine Injury Compensation Program (“Vaccine
Program”).2 In it, Mrs. Pope alleged that the Diphtheria Tetanus acellular-Pertussis (“DTaP”)
and pneumococcal conjugate (“PCV”) vaccines B.P. received on May 11, 2011, caused him to

deficiencies, exacerbated by underlying mitochondrial dysfunction. Petition at 1-2.

        After the parties filed expert reports, and based upon my initial review of the case record
in light of the disposition of similar cases previously adjudicated in the Vaccine Program, I
proposed that the matter be decided without holding an evidentiary hearing, and I invited the
parties to brief the substantive merits of Petitioner’s claim. To that end, Respondent filed a
motion to dismiss, dated August 29, 2016 (ECF No. 46) (“Mot.”), to which Petitioner responded
on November 14, 2016 (ECF No. 54) (“Opp.”). Having completed my review of the evidentiary
record and the parties’ filings, I hereby GRANT Respondent’s Motion for a Ruling on the
Record Dismissing the Case, and DENY Petitioner’s request for compensation, for the reasons
stated below.


I.      FACTUAL BACKGROUND

        Early Medical History

        B.P. was born via spontaneous vaginal delivery on February 3, 2010, following a normal
pregnancy, and he was discharged home two days later. Ex. 1 at 10-11; Ex. 2 at 1-9.3 During his
first year of life, B.P. had well-child and routine pediatric visits at Wilmington Health Clinic
(“WHC”) in Wilmington, North Carolina, with no noted growth or developmental concerns. See,
e.g., Ex. 3 at 46-115. He received his initial routine childhood vaccinations on April 6, June 8,
and August 16, 2010, respectively, and his first influenza (“flu”) vaccine on November 9, 2010.
Ex. 9 at 1-2.

       As the contemporaneous medical records reveal, B.P.’s health in his first year of life was
characterized by the kind of illnesses that many otherwise-healthy infants experience. Thus, B.P.
was seen on several occasions for a variety of infections. See, e.g., Ex. 3 at 46-48 (2/9/2011,
diagnosed with nasopharyngitis/viral infection), 51-52 (12/21/2010, diagnosed with bronchitis,
possibly viral), 64-65 (11/9/2010, diagnosed with sinusitis), 75-81 (8/31/2010, 9/1/2010, and
9/8/2010, diagnosed with presumed infectious diarrhea, viral illness, and a canker sore), 86-90
(6/10/2010 and 6/25/2010, diagnosed with viral infection and presumed infectious diarrhea),
106-08 (3/16/2010, diagnosed with viral nasopharyngitis). Starting on March 24, 2010, at
approximately seven weeks of age, B.P. was also diagnosed with and treated for chronic otitis
media (“OM”). Id. at 49-104. B.P. underwent bilateral tympanostomy tube placement in his ears
in December 2010 to treat the condition. Id. at 49-51, 54-58.

alphabetically.

                                                    2
        Despite the above, Petitioner contends that the record omits important details about
B.P.’s health – particularly his reaction to the vaccines he received prior to those at issue herein.
Thus, Mrs. Pope maintains that after each round of the aforementioned vaccinations, B.P. would
experience a high fever, arch his back, and cry uncontrollably. See, e.g., Ex. 60 (Affidavit of
Christina Pope) at ¶¶ 2-7. Mrs. Pope alleges that her questions about these reactions were not
taken seriously, however, nor did treaters even record them. Id. at ¶¶ 5-6. Thus, at his four-month
well-child check on June 8, 2010, B.P. (in good health at the time) received several additional
vaccinations. Ex. 3 at 92, 94. Two days later, on June 10, 2010, B.P. returned to the pediatrician
due to a fever and congestion, which was diagnosed as merely a viral reaction (when according
to Mrs. Pope, it was evidence of his vaccine sensitivity). Id. at 89- 90; Ex. 60 at ¶ 2.

        The first half of 2011 mirrored 2010 in terms of B.P.’s health and the treatments he
received, with additional immunizations administered at the appropriate times. See, e.g., Ex. 9 at
1-2. B.P. was seen in March and April 2011, much like the prior year, for upper respiratory
infections and comparable conditions (i.e. a runny nose or congestion) and received treatment for
the same. Ex. 3 at 40-45. No developmental concerns were noted for B.P. in this time period.
See, e.g., id. at 46-48 (records from B.P.’s one-year well-child visit on February 9, 2011).

       Receipt of May 2011 Vaccines and Subsequent Medical History

        B.P. had his fifteen-month well-child visit on May 11, 2011. Ex. 3 at 37-39. B.P.’s
development remained normal, and by this point in his life he could stand alone, stoop and
recover, walk well, say two words together, wave “bye-bye,” say “Dada [and] Mama - Specific,”
and mimic activities. Id. at 37. At this time, he received his fourth dose of the PCV vaccine and
first DTaP vaccine dose. Id. at 39; Ex. 9 at 3. Immediately thereafter, Mrs. Pope alleges B.P.
again spiked a fever and was very irritable and lethargic for the next several days, although the
medical records do not corroborate these contentions. Ex. 60 at ¶¶ 6-8. Petitioner also claims to
have reported to the pediatrician that B.P.’s eye contact was intermittent, but she was informed
that there were no grounds for worry. Id.

        The remainder of May and the first half of June passed without medical incident. Then,
six weeks after receiving the vaccinations in question, on June 28, 2011, B.P. was taken back to
WHC with a two-day history of fussy behavior and touching his ears without a fever. Ex. 3 at 35-
36. The record, however, reflects that B.P. was teething, and his physical exam was otherwise
normal. Id. B.P was seen again at WHC on July 13, 2011, at seventeen months of age, for a six-
month follow-up for his tympanostomy tubes. Id. at 33-34. His pediatrician noted that B.P. had
normal communication for his age and that his tubes remained in place. Id. B.P. continued to be
seen at WHC throughout his second year of life for upper respiratory and ear infections. See id.
at 22-31.



                                                 3
        Evidence of Developmental Problems and/or Regression

        The parties dispute when B.P. first began to display signs of developmental problems or
regression. Petitioner argues that manifestations of B.P.’s developmental problems began
immediately after the May 2011 vaccinations. Thus, Mrs. Pope maintains that post-vaccination,
B.P. could no longer point his index finger, catch and throw a ball, march his feet, or wave his
hand for “hi” or “bye-bye.” Ex. 60 at ¶ 9. She also alleges that he lost the ability to shake his
head “no” or nod his head “yes,” could not identify body parts, and experienced deterioration of
language skills, including losing words he had previously used, such as “mama” and “dada.” Id.
Mrs. Pope consistently alleges that she informed the pediatrician of her observations of B.P.’s
regression, but she was told that it was normal or that it could be harmful to B.P.’s future
(especially once in school) to record the possibility that B.P. was experiencing autism or a
similar developmental problem in the treatment history. Id. at ¶ 10.

        By contrast, the contemporaneous record shifts the onset of B.P.’s problems to a much
later date – early 2012, eight months after the relevant vaccinations – and reflects no instance
until that time in which either Petitioner or a treater noted any concerns about B.P.’s
development. Thus, on January 4, 2012, Petitioner took B.P. (now twenty-three months old) to
WHC for congestion that had been ongoing for one week, plus a diaper rash that had worsened
over the past two days. Ex. 3 at 19-21. At this visit, Mrs. Pope is recorded as stating that her in-
laws had expressed concern that B.P. had autism, because he would wave his arms when he was
upset and spoke few two-word sentences. Id. The pediatrician’s notes echo these concerns,
noting that B.P.’s speech “may be a bit delayed,” but he otherwise determined that B.P.’s
behavior was within the “realm of normal” and diagnosed him with OM, a diaper rash, and
possible developmental delay. Id. at 21. B.P.’s treater requested that B.P. be seen again in one
month in order to assess whether additional developmental symptoms warranted further
evaluation. Id.

         B.P. was brought back to his pediatrician’s office on January 31, 2012, for a sick visit,
where he was diagnosed with bronchiolitis and OM, but there was no further mention of any of
the developmental concerns expressed at the January 4th visit. Ex. 3 at 17-18. B.P.’s pediatrician
thereafter saw him three more times in February 2012 for bronchiolitis and OM. Id. at 9-16. He
was also seen for a rash on March 13, 2012. Id. at 7-8. The contemporaneous notes from these
visits are similarly silent on the matter of additional developmental concerns.

       On May 18, 2012, B.P. was evaluated for several episodes of purulent otorrhea4 and was
diagnosed with Eustachian tube dysfunction. Ex. 3 at 4-6. The pediatrician noted that B.P.’s
hearing appeared normal, but that Mrs. Pope would be obtaining a speech evaluation for B.P. Id.

 An otorrhea is a discharge from the ear; purulent otorrhea indicates that the discharge contains pus. See Dorland’s
Medical Dictionary 1351, 1558 (32nd ed. 2012) (hereinafter Dorland’s).

at 6. The records from this visit include “developmental delay” in B.P.’s medical history, but the
examination from this visit (which is limited in description) does not set forth any specific
observations of developmental problems in communication or physical acts. Id. at 4-6.

         Petitioner returned to WHC with B.P. (then twenty-eight months old) “to discuss
behavior issues and development” on June 21, 2012. Ex. 3 at 1. She now reported that B.P. was
still flapping his hands and would become overstimulated if he saw something that upset him. Id.
She also stated (for the first time in the contemporaneous records) that B.P.’s speech was delayed
– he knew some words and occasionally put two words together, but he mostly babbled and
seemed “a little tongue-tied.” Id. The pediatrician noted that B.P.’s fine and gross motor skills
appeared normal, along with his hearing, but that he did display some sensory issues. Id. B.P.
was accordingly diagnosed with speech delay and possible developmental delay. Id. at 3. While
the pediatrician did not express the formal view that B.P. was on the autism spectrum, he
nevertheless referred him for a developmental evaluation. Id.

       On July 19, 2012, Petitioner took B.P. to the Wilmington Children’s Developmental
Services Agency (“CDSA”) for an evaluation, and he was diagnosed with autism, delayed
milestones, and a language disorder. Ex. 18 at 3-10. As such, he was found eligible for the North
Carolina Infant-Toddler Program.5 Id. at 1, 9. The detailed narrative of the CDSA report
describes delays in various skills, but it does not appear to mention any regression. Id. at 3-10. It
also contains no statements regarding when the Popes, or any of B.P.’s other caregivers, first
noticed his developmental problems.

        Dr. Harum’s Treatment of B.P.

        On July 31, 2012, B.P. began seeing Karen Harum, M.D., at the Clinic for Special
Children, because of his parents’ concerns about his autism diagnosis. Ex. 5 at 38-40. B.P.’s
parents reported that he had stopped using words and naming body parts “closer to two years
[old],” (or around February 2012 – nine months from the vaccinations at issue), although they
also asserted that his developmental problems were first evident after the 15-month-old
vaccinations at issue herein. Id. at 38 (B.P. “suddenly changed” after receiving the vaccinations
in May 2011). These records also present the first instance in which developmental regression
(as opposed to delay) is mentioned as a concern. Id. at 38.6

  As already noted, Mrs. Pope has alleged (in her witness affidavits, as well as some history recitations made to
treaters after this date) that she observed B.P.’s regression prior to this time.


                                                       5
        The records from the Popes’s first visit with Dr. Harum in July 2012 contain a variety of
representations about B.P.’s medical history that are contradicted, or at least not corroborated, by
prior contemporaneous medical records.7 In particular, Petitioner appears to have informed Dr.
Harum that B.P. had experienced a low grade fever and a diarrheal illness right after the May
2011 vaccinations, followed by a gradual loss in skills – when the contemporaneous medical
records mention no such reaction or symptoms. See, e.g., Ex. 3 at 24-39 (no record of a low
grade fever, diarrheal illness, or loss of skills in the five months following B.P.’s fifteen-month
vaccinations). Dr. Harum also included in her initial notes that B.P. had regressed after
placement of his tympanostomy tubes “coincident with the period of illness following vaccines”
(Ex. 5 at 38), even though B.P.’s tubes were placed in December 2010 – almost six months
before the fifteen-month-old visit – and contrary to the Popes’s other representations that the
fifteen-month-old visit demarcated the change in B.P.’s development. Ex. 3 at 37-39, 49-51; Ex.
9 at 1-2.

        On examination, Dr. Harum observed that B.P. demonstrated a normal interest in toys
and had good core stability but poor eye contact. Ex. 5 at 40. Dr. Harum assessed his language
ability at the fifteen-month level. Id. On the Gilliam Autism Rating Scale (based on a
questionnaire that Petitioner completed), B.P. had an autism index of 76, indicating possible
autism, although Dr. Harum felt that the prior diagnosis, coupled with B.P.’s purported (but
uncorroborated by the contemporaneous medical record) “history of encephalopathic regression
into autistic behaviors,” made it appropriate to diagnose B.P. with autistic regression, moderate
language delay, and inflammatory encephalopathy. Id.

        Dr. Harum subsequently ordered some genetic testing (including a chromosomal
microarray, Fragile X testing, and karyotyping), but the results returned in August 2012 were
normal. Ex. 5 at 90, 113-16. B.P. returned to Dr. Harum for a follow-up visit on September 6,
2012. Id. at 36. Dr. Harum noted at this time that “[a] review of the laboratory data suggests that
there are deficits in mitochondrial function and accumulation of lactic acid.” Id. (referencing Ex.
5 at 96, 98). During another follow-up visit on September 24, 2012, Dr. Harum noted that
additional laboratory results indicated an immunoglobulin G (“IgG”) deficiency,8 elevated white
blood cell count with lymphocytosis, and persistent markers of mitochondrial dysfunction, such



7
  For example, the Popes informed Dr. Harum that B.P. had received the MMR, Hep A, Varicella, and flu vaccines
at his fifteen-month-old visit, when in fact B.P. had received those three months before, on February 23, 2011, when
he was one year old. Ex. 9 at 1-2. B.P. actually received only the DTaP and PCV vaccines at fifteen months of age.
Id. at 3; Ex. 3 at 39.

 IgG is a glycoprotein that functions as an antibody. Dorland’s at 919. An IgG deficiency makes an individual more

as increased creatine kinase levels.9 Ex. 5 at 34. She prescribed prednisone “to halt cerebral
inflammation,” and noted that B.P. was likely an excellent candidate for IVIG treatment,
although the notes do not explain her basis for her recommendation. Id. at 34-35.

        Dr. Harum saw B.P. several times between October 2012 and January 2013. See
generally Ex. 5 at 24-35. She maintained throughout this time that her treatments were effective
and appropriately targeted at the alleged sources of B.P.’s developmental problems, based upon
her apparent assumption that B.P. suffered from some kind of underlying immune dysfunction.
But other contemporaneous treaters disagreed. For example, Joseph Roberts, M.D., evaluated
B.P. at Dr. Harum’s request on November 12, 2012, at the Duke University Hospital Pediatric
Allergy and Immunology Department to assess B.P.’s recurrent infections and their possible
etiology. Ex. 23 at 7-12. At that time, Dr. Roberts reviewed all of B.P.’s prior lab work and
ordered some additional testing as well. After the new testing was completed and considered, Dr.
Roberts determined – contrary to Dr. Harum – that B.P.’s lab “results demonstrate that he has
normal antibody function and IVIG is not indicated.” Id. at 11. He also opined that B.P.’s
“mildly decreased IgG level [was] likely due to transient hypogammaglobulinemia10 of infancy,
which [he] would expect to resolve over time.” Id. Dr. Roberts recommended that B.P.’s total
IgG level be reassessed in six months, but B.P. was never brought back to Dr. Roberts for a
follow-up visit. Id.; Ex. 16 at 1.

        Dr. Harum nevertheless continued to propose treatments for B.P. based upon the
supposition that he possessed some form of immune dysfunction that his immunizations had
affected. Dr. Harum also began to express the opinion that B.P.’s IgG deficits were linked to
mitochondrial insufficiency11 (in contrast to Dr. Roberts’s view that any IgG deficiencies were
merely transient). See, e.g., Ex. 5 at 29. She recommended treatment with subcutaneous
immunoglobulin therapy (Hizentra), which B.P. started on February 1, 2013. Id. at 22, 69; see
also Ex. 16 at 1. On March 8, 2013, Dr. Harum wrote a letter recommending that B.P. continue
to receive home-based services until his IgG counts were in the normal range and proposed

  Creatine kinase is an enzyme that catalyzes the phosphorylation of creatine by adenosine triphosphate (“ATP”) to
form phosphocreatine. The reaction stores the energy of ATP as phosphocreatine in muscle and brain tissue and
holds the muscle concentration of ATP nearly constant during the initiation of exercise. Dorland’s at 429. Increased
creatine kinase level can sometimes suggest the presence of a mitochondrial dysfunction or other metabolic disease.
See, e.g., Madariaga v. Sec’y of Health & Human Servs., No. 02-1237V, 2015 WL 6160215, at *21, 46 (Fed. Cl.
Spec. Mstr. Sept. 26, 2015).
10
  Hypogammaglobulinemia refers to the condition of abnormally low levels of all classes of immunoglobulins in
the blood. Dorland’s at 901.
11
   As discussed in greater detail below, a mitochondrial disorder is caused by mutations or dysfunction of
mitochondrial DNA. Dorland’s at 539. The disorder affects tissues with a high rate of oxidative metabolism,
including the brain and peripheral nervous system, and (through hampering the body’s cellular energy production
systems) can result in encephalopathy, peripheral neuropathy, vision and hearing deficits, muscle pain and
weakness, and developmental delays. Id.


                                                         7
additional Hizentra injections as well. Ex. 5 at 69. She did note, however, that B.P. was still
experiencing symptoms of autism (such as stimming) or immune deficiency (ongoing and
repeated upper respiratory infections) despite her recommended treatments. Id. Dr. Harum
treated B.P. for the remainder of 2013, during which time her initial diagnosis remained
consistent.12 Ex. 8 at 1-14.

           Evidence of Purported Mitochondrial Dysfunction

        At some time late in the fall of 2013, Mrs. Pope sought an evaluation of B.P. from
Richard Frye, M.D., at Arkansas Children’s Hospital.13 In December 2013, Dr. Frye ordered a
buccal swab14 enzyme analysis intended to measure B.P.’s mitochondrial function. Ex. 14 at 1.
The result of this test was deemed generally normal, indicating at worst a moderate deficiency in
respiratory complex I activity that was not considered definitive. Ex. 11 at 1; Ex. 16 at 2. Other
laboratory testing performed while B.P. was under Dr. Frye’s care demonstrated that B.P.’s
amino acids, creatine kinase, and urine organic acids levels were all normal. Ex. 11 at 2-5. There
was evidence of a single abnormal acylcarnitine elevation in C3 dicarboxylic acid (Ex. 17 at 1),
but Dr. Dwight Koeberl, a Duke Hospital geneticist who later evaluated B.P. in April 2014,
characterized this test result as “likely secondary to normal variation in metabolism,” and
therefore of no clinical significance. Ex. 16 at 2. Genetic testing for MECP2 and congenital
disorders of glycosylation were also negative. Id.

       Despite the above, Petitioner and certain of B.P.’s treaters pressed on with their theory
that some underlying (but previously-undiscovered) mitochondrial dysfunction was partly to
blame for B.P.’s developmental problems. Thus, on December 13, 2013, Dr. Frye wrote a


12
     For example, on December 15, 2013, Dr. Harum described B.P.’s condition as follows:

           [B.P.] presented with the typical features of encephalopathic regression into autism following a seemingly
           normal course of infantile development. Prior to this rather acute onset of regression, he suffered many
           infections, food allergies, reflux, and chronic yeast dermatitis. He received many antibiotics and
           respiratory treatments and routine immunizations. Surgery for placement of [tympanostomy tubes] at 15
           months, coincident with an illness and vaccines corresponded in time to the onset of encephalopathy.

Ex. 10 at 1. Additionally, she maintained that B.P.’s immune system was “greatly compromised by an abnormal
complement of intestinal bacteria, and by the plethora of markers suggesting a mitochondrial disorder.” Id.

  Dr. Frye has previously testified on behalf of petitioners in the Vaccine Program in other cases involving alleged
mitochondrial disorders, but he has not submitted opinions in Vaccine Program cases since moving to his current
position at Arkansas Children’s Hospital, nor did he offer an opinion in this case. See, e.g., Bast v. Sec’y of Health &
Human Servs., No. 01-565V, 2012 WL 6858040 (Fed. Cl. Spec. Mstr. Dec. 20, 2012), mot. for review den’d, 117
Fed. Cl. 104 (2014). Many Program petitioners claiming that their child possessed some underlying mitochondrial
disorder that was exacerbated by a vaccine have consulted with Dr. Frye. See, e.g., R.V. v. Sec’y of Health & Human
Servs., No. 08-504V, 2016 WL 3882519 (Fed. Cl. Spec. Mstr. Feb. 19, 2016), mot. for review den’d, 127 Fed. Cl.
136 (Fed. Cl. July 1, 2016), appeal dismissed, No. 16-2400 (Fed. Cir. Oct. 26, 2016); Bast, 2012 WL 6858040.

     A buccal swab is a swab of the cheek intended to collect bacteriological material. See Dorland’s at 257, 1813.

“Telemedicine Note” based on his evaluation of B.P.’s purported “developmental
encephalopathy.” Ex. 17 at 1-2. That letter confirmed the generally inconclusive testing results
regarding possible mitochondrial dysfunction (beyond the single buccal swab analysis results),
but made no assertion as to a proper diagnosis. Id. at 1. After reviewing the unsuccessful
treatments B.P. had undergone over the past months (such as vitamin courses or the trial of IVIG
that resulted in a bad febrile reaction that seemed to worsen his symptoms), Dr. Frye
recommended that B.P. have mitochondrial DNA sequencing and nuclear DNA sequencing. Id.
Such mitochondrial DNA testing was performed in 2014, but it did not identify any pathogenic
or suspicious variants. Ex. 28 at 3. A comprehensive sequence analysis of nuclear mitochondrial
genes was normal, except for one heterozygous variant (NRXN1) of uncertain significance. Ex.
20 at 1.

        On April 21, 2014, B.P. returned to Duke for a “genetic evaluation for mitochondrial
disease associated with autism” with Dr. Koeberl. Ex. 16 at 1-9. The records from that visit set
forth B.P.’s history as provided by his parents, who repeated their view that B.P. had experienced
developmental regression shortly after his twelve-month vaccinations when he purportedly lost
words, with other behavioral changes evident at fifteen months. Id. at 1. B.P.’s parents further
reported that it was Dr. Harum who first mentioned in October 2012 that B.P. might have
possible mitochondrial dysfunction. Id.

       Dr. Koeberl reviewed all of the genetic and metabolic laboratory evaluations to date,
which largely concluded that B.P.’s results were normal, and recommended additional testing.
Ex. 16 at 2-3, 9-10. Subsequent testing for blood lactate, uric acid, and urine organic acids levels
was also normal, however, and there was no evidence of a congenital disorder of glycosylation
or a defect of creatine synthesis or transport. Id. at 10-19. In light of such results, although Dr.
Koeberl allowed for the possibility that B.P.’s clinical presentation “could be caused by a
mitochondrial disorder,” the records from this examination do not reflect that Dr. Koeberl ever
made such a diagnosis. Id. at 8-9.

       Subsequent Evaluations of B.P.’s Condition and its Possible Etiology

        B.P. continued to be followed by Dr. Harum in 2015 and 2016 for his autism, but
attempts to identify the source of his developmental symptoms produced inconclusive results.
See generally Exs. 27, 31-32, 37, 41-42, 44, 51. For example, an ambulatory
electroencephalogram (“EEG”) performed in January 2015 was normal. Ex. 24 at 1. Whole
exome sequencing was also ordered, but it did not detect any clinically significant variants or a
genetic explanation for B.P.’s autism or speech delay. Id.; Ex. 30 at 1-2. Thus, an Autism
Multispecialty Clinic patient summary phone note from January 28, 2015, reflects the
predominating view of B.P.’s treaters at the time that the etiology of B.P.’s autism spectrum
disorder (“ASD”) remained unclear. Ex. 28 at 1.


                                                 9
        On March 26, 2015, B.P. was evaluated by Francis Kendall, M.D.15 Ex. 25 at 1-7. At this
visit, Mrs. Pope again misreported B.P.’s history of regression following immunizations with
fevers at twelve- and fifteen-months of age. Id. at 1. Dr. Kendall, relying upon the recited
medical history, noted that “[b]ased on his history of regressive autism associated with fever[,]
several evaluating physicians, including a neurodevelopmental pediatrician, felt he had features
of mitochondrial disease . . .” Id. at 1-2. Yet these records suggest that Dr. Kendall was reluctant
to embrace the diagnosis, characterizing B.P. merely “as a possible mito[chondrial] patient.” Id.
at 5 (emphasis added). Overall, this record establishes that Dr. Kendall’s assessment was heavily
dependent on assumptions about B.P.’s history and prior treatment assessments (which in turn
were also based on Petitioner’s assertions), rather than her own objective findings or the test
results set forth in B.P.’s medical history.

       By June 2015, B.P. was again receiving Hizentra infusions. Ex. 31 at 6-11; Ex. 32 at 1-4;
Ex. 39 at 5-9. B.P. saw Dr. Kendall in December 2015 for a follow-up visit. Ex. 43 at 1-5. In the
interim, B.P. was reported to be experiencing intermittent ataxia and had several eye infections
despite the weekly Hizentra infusions intended to stop these infections (based on Dr. Harum’s
supposition that they were a product of immune system dysfunction). Id. After examination, Dr.
Kendall reiterated her prior, inconclusive assessment of B.P. as “possible” for mitochondrial
dysfunction. Id.

        On February 1, 2016, B.P. was again evaluated for mitochondrial disorder or dysfunction,
this time by a pediatric neurologist, Sasidharan Taravath, M.D. Ex. 46 at 6-11. Dr. Taravath
acknowledged that the clinical diagnosis of a mitochondrial myopathy for B.P. had never been
proven “either by DNA test or muscle biopsy.” Id. at 6-7. After examination, he concluded that a
diagnosis of mitochondrial myopathy was only “possible.” Id. at 10. That same month and into
March 2016, an urologist and nephrologist at Duke also evaluated B.P. for reported hematuria
and proteinuria. Ex. 48 at 1-11; Ex. 50 at 3-13. A urinalysis at that time was normal, as was a
renal bladder ultrasound. Id. The nephrologist found that B.P. “has no renal/urinary
abnormality.” Ex. 50 at 11.16

15
   Like Dr. Frye, Dr. Kendall has frequently testified on behalf of petitioners in other Vaccine Program cases
involving autism and/or an alleged mitochondrial disorder, although she did not offer an opinion in this case. See,
e.g., R.K. v. Sec’y of Health & Human Servs., No. 03-632V, 2015 WL 10936124 (Fed. Cl. Spec. Mstr. Sept. 28,
2015), mot. for review den’d, 125 Fed. Cl. 57 (2016), aff’d, No. 16-1609 (Fed. Cir. Dec. 9, 2016); R.V., 2016 WL
3882519; H.L. v. Sec’y of Health & Human Servs., No. 10-197V, 2016 WL 3751848 (Fed. Cl. Spec. Mstr. Mar. 17,

  Petitioner has continued to file additional records since filing her brief in opposition on November 14, 2016. See
ECF Nos. 55, 57-59 (Exs. 62-72). These records pertain to recent medical visits from the end of 2016 to 2017,
including updated lab results, updated records from Duke Children’s Health Center ENT, and records from Duke
Eye Center. See Exs. 70-72. I have reviewed these recently filed records in detail. However, the updated records do

II.     EXPERT REPORTS

        A.      Dr. Karen Harum

       Dr. Harum, one of B.P.’s aforementioned treaters, has offered an opinion in this case in
support of Petitioner’s causation theory. See generally Report, dated August 3, 2015 (ECF No.
30-1) (Ex. 33) (“Harum Rep.”).

        As her CV indicates, Dr. Harum has a private clinical practice as a pediatrician at the
Clinic for Special Children in Wilmington, North Carolina. See ECF No. 30-2 (Ex. 34) (“Harum
CV”), at 1. She is board certified in pediatrics with a certification in neurodevelopmental
disabilities. Id at 3. Dr. Harum received her M.D. from the University of Miami School of
Medicine in 1987 and completed a residency in the Department of Pediatrics at the University of
Miami School of Medicine from 1988-1991. Id. at 2. Prior to her current position, Dr. Harum
was a clinical assistant professor at the Eastern Carolina School of Medicine and an instructor at
the Kennedy Krieger Institute Department of Pediatrics at the Johns Hopkins University School
of Medicine, where she also completed her fellowship and post-doctoral fellowship. Id. at 1-2.
Dr. Harum’s CV lists approximately eight peer-reviewed articles that were published between
1997 and 2002, along with three book chapters and seven abstracts (id. at 4), although she has
“not written any articles relevant to the specific issues in this case.” Harum Rep. at 1.

       Dr. Harum’s report does not set forth, in the usual sense (as far as Vaccine Program cases
go), an opinion as to how the vaccines that B.P. received in May 2011 produced his alleged
developmental regression or ASD, or whether they could do so generally. Rather, it summarizes
information contained in Petitioner’s exhibits 1 through 22. See generally Harum Rep. at 1-5.
Although it recites facts that Dr. Harum and Petitioner likely believe support Petitioner’s claim,
the report contains very little in the way of expert opinion or analysis explaining how the
vaccines at issue purportedly caused B.P.’s developmental problems – nor does it offer any
medical or scientific literature in support of its presumed opinions.

       For example, Dr. Harum notes that Petitioner’s consultation with Dr. Kendall in 2015
“suggests that mitochondrial deficits are present,” and she contends that finding is corroborated
by the buccal swab analysis obtained in 2013 by Dr. Frye that suggested a moderate deficiency
of complex I activity. Harum Rep. at 4. But this merely restates what the records (arguably)
show – it does not stand as independent or interpretive analysis. Dr. Harum’s report therefore
does not set forth an explanation for how B.P.’s autism is possibly linked to his vaccinations,
based upon Dr. Harum’s expertise in the relevant field, nor does it provide any explanation or


not contain any information contrary to what was previously filed, and do not otherwise cause me to change my
analysis, and therefore they are not discussed at length herein.

                                                     11
theory as to how the alleged vaccines were a substantial factor in bringing about B.P.’s autism –
although it can reasonably be assumed from the report (and as reflected in the treatment history)
that she holds that opinion.

        B.       Dr. Marcel Kinsbourne

        Dr. Kinsbourne prepared Petitioner’s other expert report, which attempts to provide the
explanation of a link between B.P.’s regression/autism and his PCV and DTaP vaccinations that
is missing from Dr. Harum’s report. See Report, dated September 30, 2015 (ECF No. 32-1) (Ex.
35) (“Kinsbourne Rep.”).

        As his CV indicates, Dr. Kinsbourne is board certified in pediatrics. ECF No. 32-2 (Ex.
36) (“Kinsbourne CV”), at 1. He received his medical degree in England, and he has been
licensed to practice medicine in North Carolina since 1967. Id. From 1967 to 1974, Dr.
Kinsbourne served as an associate professor in pediatrics and neurology and a senior research
associate at Duke University Medical Center before holding a series of academic positions,
including professorships in pediatrics, neurology, and psychology. Id. at 2. His clinical
experience includes serving as a senior staff physician in Ontario from 1974-1980, and a clinical
associate in neurology at Massachusetts General Hospital from 1981-1991, although (as noted in
other cases) many years have passed since he regularly saw patients. He has published several
articles examining autism (Kinsbourne CV at 15, 21-22, 27), and he is on the editorial board of
several journals that deal with the brain, such as Brain and Cognition and Brain Research.
Kinsbourne CV at 3.

        Dr. Kinsbourne opines that B.P. suffers from an “autistic type” mitochondrial
encephalopathy that was produced by his fifteen-month DTaP and PCV vaccinations, which
significantly aggravated a pre-existing “asymptomatic mitochondrial deficiency.” Kinsbourne
Rep. at 3-6. In particular, he proposes that the May 2011 vaccinations interfered with B.P.’s
subclinical mitochondrial dysfunction (not discovered in B.P. until years later) by increasing
oxidative stress, which then clinically manifested as autistic regression. Id. at 4-5. Dr.
Kinsbourne does not propose that these vaccines directly caused B.P.’s developmental problems,
but that they significantly aggravated his alleged underlying mitochondrial disorder. See id. at 6.

        In his report, Dr. Kinsbourne explains that mitochondria, the organelles in the body’s
cells responsible for energy production, are vulnerable to oxidative stress. Vaccines can generate
oxidative stress by activating the immune system, producing proinflammatory cytokines17 which
can tip the balance of reactive oxygen species, resulting in cell damage and (later) autistic

17
  Cytokine is a generic term for non-antibody proteins released by one cell population on contact with specific
antigen, which act as intercellular mediators, as in the generation of an immune response. Dorland’s at 466.
Proinflammatory signifies that these cytokines are capable of stimulating inflammation. Id. at 1523.


                                                      12
symptoms once the damage arrives in the brain. Kinsbourne Rep. at 5-6. The report does not
explain, however, how much oxidative stress is generated by vaccination generally (or the
vaccines in question specifically), nor does it propose what level of oxidative stress is necessary
to cross the “tipping point” to cause clinical disease manifesting as autism or how long this
cytokine production would be maintained post-vaccination. Nor, based on his CV, does it appear
that Dr. Kinsbourne has the specific experience in the fields of immunology, mitochondrial
function, or metabolic disorders to opine credibly on these topics, despite his pediatric and
neurologic expertise.

        Dr. Kinsbourne’s opinion is premised upon several factual assumptions, including that
B.P. (1) suffered from a “mitochondrial encephalopathy, autistic type”; (2) regressed after his
fifteen-month vaccinations on May 11, 2011; and (3) had a preexisting underlying “genetically
based susceptibility” in cellular energy metabolism “caused by his deficiency in the function of
mitochondrial chain complex 1.” Kinsbourne Rep. at 3-5. The foundation for these assumptions,
however, appears to be Petitioner’s own statements about B.P.’s condition rather than the
medical records, particularly with respect to onset of his developmental problems – a fact Dr.
Kinsbourne admits. Id. at 3 (“the pediatric records do not offer any assistance as to when [B.P.]
began to suffer autistic regression”).

        The timing of B.P.’s purported regression is dispositive to Dr. Kinsbourne’s opinion, as is
B.P.’s alleged mitochondrial susceptibility/dysfunction. See, e.g., Kinsbourne Rep. at 3
(“[w]hether the DTaP and Prevnar vaccinations constitute the risk factor that transformed the
disorder from a subclinical to a clinical level depends in the first instance on when the autistic
regression began”). To support his opinion, Dr. Kinsbourne references approximately eight
studies or articles, although not all were filed in this action.18

       Overall, Dr. Kinsbourne opined that vaccinations activate immune system cells, which in
turn generate oxidative stress. Therefore, he believed it to be medically reasonable that
mitochondria could be stressed by one or more vaccinations and cause, among other things, a
mitochondrial encephalopathy with autistic features. Kinsbourne Rep. at 6.

        C.       Dr. Bruce Cohen

        Dr. Cohen provided an expert report for Respondent. Dr. Cohen is board certified in
pediatrics and neurology, with special competence in child neurology. Report, dated March 14,
2016 (ECF No. 40-1) (Ex. A) (“Cohen Rep.”), at 1; ECF No. 40-2 (Ex. B) (“Cohen CV”), at 2.

18
   In fact, Petitioner only filed two of the articles referenced in Dr. Kinsbourne’s report – Poling et al.,
Developmental Regression and Mitochondrial Dysfunction in a Child with Autism, 21 J. Child Neurol. 170: 170-172
(2006) (filed as Ex. 63) (“Poling”), and Shoffner et al., Fever Plus Mitochondrial Disease Could be Risk Factors for
Autistic Regression, 25 J. Child Neurol. 429: 429-434 (2010) (filed as Ex. 64) (“Shoffner”).


                                                        13
Previously, Dr. Cohen completed his pediatric residency and a two-year fellowship at Children’s
Hospital of Philadelphia, and a pediatric neurology residency at Columbia Presbyterian Medical
Center. Cohen Rep. at 1. He also worked for more than twenty-one years at The Cleveland Clinic
practicing as a child neurologist specializing in children and adults with brain tumors and
mitochondrial disease. Id. Dr. Cohen has received numerous honors and awards, and he has also
served on various advisory groups, editorial boards, and review panels over the course of his
career. Cohen CV at 2-3. He is a member of several professional societies, including the
American Academy of Neurology, Child Neurology Society, Mitochondrial Research Society,
and the Mitochondrial Medicine Society. Id. at 2. He currently serves as the Director of the
NeuroDevelopmental Science Center and the Director of Neurology at the Children’s Hospital
Medical Center of Akron, as well as a Professor of Pediatrics at the Northeast Ohio College of
Medicine. Id. at 1.

        Dr. Cohen has demonstrated experience and expertise in the field of mitochondrial
disorders and diseases. His peers have elected him to serve in both the areas of mitochondrial
medicine and child neurology. Cohen Rep. at 3. He has conducted original peer-reviewed
research and written extensively in the field of mitochondrial disease, recently co-authoring a
textbook of mitochondrial medicine. Id. Today, Dr. Cohen has an active clinical practice as a
child neurologist specializing in mitochondrial disease. Id. at 1-2. As part of his clinical practice,
Dr. Cohen routinely orders testing to evaluate and diagnose mitochondrial disease. Id. He has
also evaluated hundreds of children with developmental delays or regression and autism
spectrum disorders. Id. at 1.

        Based on a careful evaluation of the evidence, including the various test results from
B.P.’s treatment by Drs. Frye and Harum, Dr. Cohen opined that B.P. does not have a
mitochondrial illness, dysfunction, or disease, nor did he suffer an encephalopathy or regression
temporally following either his twelve-month or fifteen-month vaccinations. Cohen Rep. at 13-
22. Rather, B.P. more likely suffers from idiopathic autism typical of many children, as reflected
in his clinical course established by the contemporaneous medical records. Id. at 13, 14. Dr.
Cohen thus disagrees with Dr. Kinsbourne that B.P. suffered from a vaccine-related
encephalopathy or that any of his vaccinations was a substantial factor in the development of his
autism. Id. at 21-22.

        In support of his opinion, Dr. Cohen provided a very careful and detailed explanation of
how an experienced mitochondrial specialist investigates for a possible mitochondrial problem,
citing to generally-accepted diagnostic criteria and supporting medical literature. See Cohen Rep.
at 13-19. At the outset, Dr. Cohen observed that B.P. lacked any of the presenting clinical criteria
that would “be part of the primary mitochondrial phenotype,” setting forth a lengthy list of
several clinical criteria (for example, MRI evidence of brain lesions) that were absent from
B.P.’s records. Id. at 14. He also noted that B.P.’s presentation as detailed in the medical records


                                                 14
was not consistent with any recognized form of mitochondrial disease, like Leigh disease19 or
MELAS.20 Id. Dr. Cohen agreed (as Dr. Kinsbourne proposed) that “autism can be seen in
children who also have mitochondrial disorders,” but he added that not only have mitochondrial
diseases and dysfunctions not been causally linked to autism, but also that autistic children found
to possess a mitochondrial disorder “have additional clinical features or diagnostic biochemical-
genetic-histological features” absent herein. Id.

        Given the lack of obvious and compelling direct evidence of mitochondrial disease or
disorder in this case, Dr. Cohen noted that determining if a patient such as B.P. truly possessed
any kind of mitochondrial dysfunction would require one of two kinds of evidence: genetic
testing proof (absent here, as the aforementioned factual history revealed), or lab tests
confirming the existence of mitochondrial problems. Cohen Rep. at 14. Dr. Cohen’s report
explained in great detail the nature of these tests and their advantages and disadvantages – as
well as why, in this case, the testing and evaluations of B.P. did not support the diagnosis. Id. at
14-18. In Dr. Cohen’s opinion, the buccal swab analysis, genetic testing, and other laboratory
results from the medical treatment records in this case did not provide reliable support for the
conclusion that B.P. suffered from any likely mitochondrial disease or dysfunction. Id. at 16-18.
Nor did he accept the view that the frequency, type, or severity of B.P.’s childhood illnesses
during the period of time he was receiving vaccinations were abnormal for healthy children, as
none of the illnesses were life-threatening or resulted in hospitalizations. Id. Further, there were
no emergency department records associated with these visits, suggesting to Dr. Cohen that all of
the pediatric providers were able to deal with the infections, thus confirming their minor
character. Id.

           D.       Dr. Frances Kendall

        In opposing the pending motion to dismiss, Mrs. Pope represented that she had recently
contacted Dr. Kendall (one of B.P.’s treaters as discussed in the medical history section above)
about offering an expert opinion in this case (specifically as to whether B.P. suffered from some
underlying mitochondrial disease or disorder), and that she intended to file it “as soon as we
receive it.” Opp. at 22. To date, however (and now months after the filing of Petitioner’s
opposition brief) no such report has been filed, nor has Petitioner filed a status report or motion
of any kind requesting that I defer action on Respondent’s motion until the filing of such a
report.

III.     PROCEDURAL HISTORY

       As noted above, this action was initiated in January 2014. Petition at 1. From January 29
through June 25, 2014, Mrs. Pope filed B.P.’s medical records, designated as Exhibits 1 through
17. On August 25, 2014, Respondent filed his Rule 4(c) Report recommending that
compensation be denied and the Petition be dismissed. ECF No. 16.

        Thereafter, Petitioner undertook to file certain outstanding records identified in the Rule
4(c) Report, and I ordered that she file an expert report in support of her claim. See Order, dated
Sept. 15, 2014 (ECF No. 17). Six months passed without the filing of such a report, however
(although Petitioner did receive one extension to act). Then, in March 2015 (at her second
deadline for filing an expert report), Mrs. Pope requested that this matter be stayed in light of the
pending Federal Circuit decision in a different case (which has since been decided), Paluck v.
Sec’y of Health & Human Servs., 786 F.3d 1373 (Fed. Cir. 2015), which she argued could be
dispositive of this matter. Motion, dated March 31, 2015 (ECF No. 24).

        In response, I noted that there were significant facial disparities between the facts of this
case and Paluck, and therefore I did not accept at face value Petitioner’s contention that the
disposition of that case bore on the resolution of this matter (which appeared, based on the
medical records, far more akin to the vast majority of autism injury cases heard in the Vaccine
Program over the past ten years).21 Order, dated Apr. 21, 2014 (ECF No. 25). I did, however,
agree to provide Petitioner even more time to file an expert report, setting the end of August as
the deadline to do so. Id. at 2.

        On August 31, 2015, Petitioner filed Dr. Harum’s report. She also indicated at that time
that she planned to file an additional expert report but needed more time to do so, and I granted
that request. On October 1, 2015, Petitioner filed Dr. Kinsbourne’s report. I thereafter ordered

21
   In Paluck, the Federal Circuit affirmed the Court of Federal Claims’s determination that a special master had erred
in denying compensation to petitioners claiming (in a non-Table case) that the MMR, varicella, and pneumococcal
vaccines significantly aggravated their child’s mitochondrial disease, resulting in severe neurodegeneration.
However, that case is facially, and procedurally, distinguishable. The vaccinated child (a one-year old) in Paluck
had experienced a persistently high fever in the two to seven days immediately after receiving the vaccines and was
soon thereafter diagnosed with possible neurologic problems confirmed by MRI results, among other things. Paluck,
786 F.3d at 1376. This is obviously different from the present circumstances, in which the record does not reveal
any immediate reaction (outside of Petitioner’s individual allegations). Moreover, in Paluck the child’s
mitochondrial disease was not a contested fact, as here. Rather, Respondent’s expert admitted, during the initial
hearing and while under cross-examination, that the theory had plausibility. And later in the case’s history (as
observed by the special master presiding over the case after it was remanded to him the first time), Respondent
effectively dropped the issue entirely. Paluck v. Sec’y of Health & Human Servs., No. 07-889V, 2013 WL 2453747,
at *42 (Fed. Cl. Spec. Mstr. May 10, 2013) (special master noting that even though Respondent had not made an
“outright concession” of petitioners’ theory, he “did not present any substantive argument regarding prong one of

Respondent to file an expert report of his own, and Respondent subsequently filed Dr. Cohen’s
report on March 15, 2016.

        In April 2016, I held a status conference with the parties after reviewing the case record
and each side’s expert reports in greater detail. See generally Order, dated April 4, 2006 (ECF
No. 41). By this point, it was evident that Petitioner’s causation theory relied on the
determination that B.P. had an underlying mitochondrial disease or disorder exacerbated by his
vaccinations, which thereby precipitated an encephalopathic reaction that resulted in
developmental regression and B.P.’s autism diagnosis. But it was equally evident that the
medical record (which contained the most probative and reliable evidence as to B.P.’s history)
did not support such a conclusion. It also was clear that the theory being advanced in this case
was little different from those repeatedly rejected in other Vaccine Act cases, many of which had
been tried at an entitlement hearing. I thus informed Petitioner that I had serious concerns about
her claim’s viability, in light of both the history of Program claims asserting a similar theory, as
well as my own experience deciding similar cases in which mitochondrial diseases were alleged
to have been linked to an autism injury mediated by vaccination.

        Given the above, I proposed that, in lieu of a hearing, the parties brief Petitioner’s claim,
and I set a schedule for so doing. Order, dated April 4, 2016, at 2. Over several months, the
parties filed their respective briefs, as referenced at the outset of this decision. The matter is now
fully briefed and ripe for resolution.


IV.     APPLICABLE LEGAL STANDARDS

        A.       Claimant’s Burden in Vaccine Program Cases

       To receive compensation in the Vaccine Program, a petitioner must prove either: (1) that
he suffered a “Table Injury” – i.e., an injury falling within the Vaccine Injury Table –
corresponding to one of the vaccinations in question within a statutorily prescribed period of
time or, in the alternative, (2) that his illnesses were actually caused by a vaccine (a “Non-Table
Injury”). See Sections 13(a)(1)(A), 11(c)(1), and 14(a), as amended by 42 C.F.R. § 100.3; §
11(c)(1)(C)(ii)(I); see also Moberly v. Sec’y of Health & Human Servs., 592 F.3d 1315, 1321
(Fed. Cir. 2010); Capizzano v. Sec’y of Health & Human Servs., 440 F.3d 1317, 1320 (Fed. Cir.
2006).22 In this case, Petitioner does not assert a Table claim.


22
   Decisions of special masters (some of which I reference in this ruling) constitute persuasive but not binding
authority. Hanlon v. Sec’y of Health & Human Servs., 40 Fed. Cl. 625, 630 (1998). By contrast, Federal Circuit
rulings concerning legal issues are binding on special masters. Guillory v. Sec’y of Health & Human Servs., 59 Fed.
Cl. 121, 124 (2003), aff’d, 104 F. App’x 712 (Fed. Cir. 2004); see also Spooner v. Sec’y of Health & Human Servs.,
No. 13-159V, 2014 WL 504728, at *7 n.12 (Fed. Cl. Spec. Mstr. Jan. 16, 2014).

                                                        17
        For both Table and Non-Table claims, Vaccine Program petitioners bear a
“preponderance of the evidence” burden of proof. Section 13(1)(a). That is, a petitioner must
offer evidence that leads the “trier of fact to believe that the existence of a fact is more probable
than its nonexistence before [he] may find in favor of the party who has the burden to persuade
the judge of the fact’s existence.” Moberly, 592 F.3d at 1322 n.2; see also Snowbank Enter. v.
United States, 6 Cl. Ct. 476, 486 (1984) (mere conjecture or speculation is insufficient under a
preponderance standard). Proof of medical certainty is not required. Bunting v. Sec’y of Health &
Human Servs., 931 F.2d 867, 873 (Fed. Cir. 1991). In particular, a petitioner must demonstrate
that the vaccine was “not only [the] but-for cause of the injury but also a substantial factor in
bringing about the injury.” Moberly, 592 F.3d at 1321 (quoting Shyface v. Sec’y of Health &
Human Servs., 165 F.3d 1344, 1352-53 (Fed. Cir. 1999)); Pafford v. Sec’y of Health & Human
Servs., 451 F.3d 1352, 1355 (Fed. Cir. 2006). A petitioner may not receive a Vaccine Program
award based solely on his assertions; rather, the petition must be supported by either medical
records or by the opinion of a competent physician. Section 13(a)(1).

        In attempting to establish entitlement to a Vaccine Program award of compensation for a
Non-Table claim (which is the kind of claim asserted in this matter), a petitioner must satisfy all
three of the elements established by the Federal Circuit in Althen v. Sec’y of Health & Human
Servs., 418 F.3d 1274, 1278 (Fed. Cir. 2005): “(1) a medical theory causally connecting the
vaccination and the injury; (2) a logical sequence of cause and effect showing that the
vaccination was the reason for the injury; and (3) a showing of a proximate temporal relationship
between vaccination and injury.”

        Each of the Althen prongs requires a different showing. Under Althen prong one,
petitioners must provide a “reputable medical theory,” demonstrating that the vaccine received
can cause the type of injury alleged. Pafford, 451 F.3d at 1355-56 (citations omitted). To satisfy
this prong, the petitioner’s theory must be based on a “sound and reliable medical or scientific
explanation.” Knudsen v. Sec’y of Health & Human Servs., 35 F.3d 543, 548 (Fed. Cir. 1994).
Such a theory must only be “legally probable, not medically or scientifically certain.” Id. at 549.

        Petitioners may satisfy the first Althen prong without resort to medical literature,
epidemiological studies, demonstration of a specific mechanism, or a generally accepted medical
theory. Andreu v. Sec’y of Health & Human Servs., 569 F.3d 1367, 1378-79 (Fed. Cir. 2009)
(citing Capizzano, 440 F.3d at 1325-26). Special masters, despite their expertise, are not
empowered by statute to conclusively resolve what are essentially thorny scientific and medical
questions, and thus scientific evidence offered to establish Althen prong one is viewed “not
through the lens of the laboratorian, but instead from the vantage point of the Vaccine Act’s
preponderant evidence standard.” Id. at 1380. Accordingly, special masters must take care not to
increase the burden placed on petitioners in offering a scientific theory linking vaccine to injury.
Contreras v. Sec’y of Health & Human Servs., 121 Fed. Cl. 230, 245 (2015) (“[p]lausibility . . .


                                                 18
in many cases may be enough to satisfy Althen prong one” (emphasis in original)). But this does
not negate or reduce a petitioner’s ultimate burden to establish his overall entitlement to damages
by preponderant evidence. W.C. v. Sec’y of Health & Human Servs., 704 F.3d 1352, 1356 (Fed.
Cir. 2013) (citations omitted).

       The second Althen prong requires proof of a logical sequence of cause and effect, usually
supported by facts derived from a petitioner’s medical records. Althen, 418 F.3d at 1278; Andreu,
569 F.3d at 1375-77; Capizzano, 440 F.3d at 1326; Grant v. Sec’y of Health & Human Servs.,
956 F.2d 1144, 1148 (Fed. Cir. 1992). In establishing that a vaccine “did cause” injury, the
opinions and views of the injured party’s treating physicians are entitled to some weight. Andreu,
569 F.3d at 1367; Capizzano, 440 F.3d at 1326 (“medical records and medical opinion testimony
are favored in vaccine cases, as treating physicians are likely to be in the best position to
determine whether a ‘logical sequence of cause and effect show[s] that the vaccination was the
reason for the injury’”) (quoting Althen, 418 F.3d at 1280). Medical records are generally viewed
as particularly trustworthy evidence, since they are created contemporaneously with the
treatment of the patient. Cucuras v. Sec’y of Health & Human Servs., 993 F.2d 1525, 1528 (Fed.
Cir. 1993).

        However, medical records and/or statements of a treating physician’s views do not per se
bind the special master to adopt the conclusions of such an individual, even if they must be
considered and carefully evaluated. Section 13(b)(1) (providing that “[a]ny such diagnosis,
conclusion, judgment, test result, report, or summary shall not be binding on the special master
or court”); Snyder v. Sec’y of Health & Human Servs., 88 Fed. Cl. 706, 746 n.67 (2009) (“there
is nothing . . . that mandates that the testimony of a treating physician is sacrosanct—that it must
be accepted in its entirety and cannot be rebutted”). As with expert testimony offered to establish
a theory of causation, the opinions or diagnoses of treating physicians are only as trustworthy as
the reasonableness of their suppositions or bases. The views of treating physicians should also be
weighed against other, contrary evidence also present in the record – including conflicting
opinions among such individuals. Hibbard v. Sec’y of Health & Human Servs., 100 Fed. Cl. 742,
749 (2011) (not arbitrary or capricious for special master to weigh competing treating
physicians’ conclusions against each other), aff'd, 698 F.3d 1355 (Fed. Cir. 2012); Caves v. Sec’y
of Health & Human Servs., 100 Fed. Cl. 119, 136 (2011), aff'd, 463 F. App’x 932 (Fed. Cir.
2012); Veryzer v. Sec’y of Health & Human Servs., No. 06-522V, 2011 WL 1935813, at *17
(Fed. Cl. Spec. Mstr. Apr. 29, 2011), mot. for review den’d, 100 Fed. Cl. 344, 356 (2011), aff’d
without opinion, 475 Fed. App’x 765 (Fed. Cir. 2012).

       The third Althen prong requires establishing a “proximate temporal relationship” between
the vaccination and the injury alleged. Althen, 418 F.3d at 1281. That term has been equated to
the phrase “medically-acceptable temporal relationship.” Id. A petitioner must offer
“preponderant proof that the onset of symptoms occurred within a timeframe which, given the


                                                19
medical understanding of the disorder’s etiology, it is medically acceptable to infer causation.”
Bazan v. Sec’y of Health & Human Servs., 539 F.3d 1347, 1352 (Fed. Cir. 2008). The
explanation for what is a medically acceptable timeframe must also coincide with the theory of
how the relevant vaccine can cause an injury (Althen prong one’s requirement). Id. at 1352;
Shapiro v. Sec’y of Health & Human Servs., 101 Fed. Cl. 532, 542 (2011), recons. den’d after
remand, 105 Fed. Cl. 353 (2012), aff’d mem., 2013 WL 1896173 (Fed. Cir. 2013); Koehn v.
Sec’y of Health & Human Servs., No. 11-355V, 2013 WL 3214877 (Fed. Cl. Spec. Mstr. May
30, 2013), mot. for review den’d (Fed. Cl. Dec. 3, 2013), aff’d, 773 F.3d 1239 (Fed. Cir. 2014).

       B.      Standard for Significant Aggravation Claim

        In this matter, besides arguing that the DTaP and/or PCV vaccines caused B.P.’s autism
and/or autistic regression, Petitioner also offers a parallel theory that the vaccines significantly
aggravated a preexisting condition in B.P. – his purported mitochondrial disease or dysfunction.
Where a petitioner so alleges, the Althen test is expanded, and the petitioner has additional
evidentiary burdens to satisfy. See generally Loving v. Sec’y of Health & Human Servs., 86 Fed.
Cl. 135, 144 (2009). In Loving, the Court of Federal Claims combined the Althen test with the
test from Whitecotton v. Sec’y of Health & Human Servs., 81 F.3d 1099, 1107 (Fed. Cir. 1996),
which related to on-Table significant aggravation cases. The resultant “significant aggravation”
test has six components, which are:

       (1) the person's condition prior to administration of the vaccine, (2) the person’s current
       condition (or the condition following the vaccination if that is also pertinent), (3) whether
       the person’s current condition constitutes a ‘significant aggravation’ of the person's
       condition prior to vaccination, (4) a medical theory causally connecting such a
       significantly worsened condition to the vaccination, (5) a logical sequence of cause and
       effect showing that the vaccination was the reason for the significant aggravation, and (6)
       a showing of a proximate temporal relationship between the vaccination and the
       significant aggravation.

Loving, 86 Fed. Cl. at 144; see also W.C. v. Sec’y of Health & Human Servs., 704 F.3d 1352,
1357 (Fed. Cir. 2013) (holding that “the Loving case provides the correct framework for
evaluating off-table significant aggravation claims”). In effect, the last three prongs of the
Loving test correspond to the three Althen prongs.

       C.      Law Governing Factual Determinations

       The process for making determinations in Vaccine Program cases regarding factual issues
begins with consideration of the medical records. Section 11(c)(2). The special master is required
to consider “all [] relevant medical and scientific evidence contained in the record,” including
“any diagnosis, conclusion, medical judgment, or autopsy or coroner’s report which is contained
in the record regarding the nature, causation, and aggravation of the petitioner’s illness,

                                                20
disability, injury, condition, or death,” as well as “the results of any diagnostic or evaluative test
which are contained in the record and the summaries and conclusions.” Section 13(b)(1)(A). The
special master is then required to weigh the evidence presented, including contemporaneous
medical records and testimony. See Burns v. Sec’y of Health & Human Servs., 3 F.3d 415, 417
(Fed. Cir. 1993) (it is within the special master’s discretion to determine whether to afford
greater weight to contemporaneous medical records than to other evidence, such as oral
testimony surrounding the events in question that was given at a later date, provided that such a
determination is evidenced by a rational determination).

        Medical records that are created contemporaneously with the events they describe are
presumed to be accurate and “complete” (i.e., presenting all relevant information on a patient’s
health problems). Cucuras, 993 F.2d at 1528; Doe/70 v. Sec’y of Health & Human Servs., 95
Fed. Cl. 598, 608 (2010) (“[g]iven the inconsistencies between petitioner’s testimony and his
contemporaneous medical records, the special master’s decision to rely on petitioner’s medical
records was rational and consistent with applicable law”), aff’d, Rickett v. Sec’y of Health &
Human Servs., 468 F. App’x 952 (Fed. Cir. 2011) (non-precedential opinion). This presumption
is based on the linked propositions that (i) sick people visit medical professionals; (ii) sick
people honestly report their health problems to those professionals; and (iii) medical
professionals record what they are told or observe when examining their patients in as accurate a
manner as possible, so that they are aware of enough relevant facts to make appropriate treatment
decisions. Sanchez v. Sec’y of Health & Human Servs., No. 11-685V, 2013 WL 1880825, at *2
(Fed. Cl. Spec. Mstr. Apr. 10, 2013); Cucuras v. Sec'y of Health & Human Servs., 26 Cl. Ct. 537,
543 (1992), aff’d, 993 F.2d 1525 (Fed. Cir. 1993) (“[i]t strains reason to conclude that petitioners
would fail to accurately report the onset of their daughter’s symptoms. It is equally unlikely that
pediatric neurologists, who are trained in taking medical histories concerning the onset of
neurologically significant symptoms, would consistently but erroneously report the onset of
seizures a week after they in fact occurred”).

        Accordingly, if the medical records are clear, consistent, and complete, then they should
be afforded substantial weight. Lowrie v. Sec’y of Health & Human Servs., No. 03-1585V, 2005
WL 6117475, at *20 (Fed. Cl. Spec. Mstr. Dec. 12, 2005). Indeed, contemporaneous medical
records are generally found to be deserving of greater evidentiary weight than oral testimony –
especially where such testimony conflicts with the record evidence. Cucuras, 993 F.2d at 1528;
see also Murphy v. Sec’y of Health & Human Servs., 23 Cl. Ct. 726, 733 (1991), aff'd, 968 F.2d
1226 (Fed. Cir.), cert. den’d, Murphy v. Sullivan, 506 U.S. 974 (1992) (citing United States v.
United States Gypsum Co., 333 U.S. 364, 396 (1947) (“[i]t has generally been held that oral
testimony which is in conflict with contemporaneous documents is entitled to little evidentiary
weight.”)).




                                                 21
       However, there are situations in which compelling oral testimony may be more
persuasive than written records, such as where records are deemed to be incomplete or
inaccurate. Campbell v. Sec’y of Health & Human Servs., 69 Fed. Cl. 775, 779 (2006) (“like any
norm based upon common sense and experience, this rule should not be treated as an absolute
and must yield where the factual predicates for its application are weak or lacking”); Lowrie,
2005 WL 6117475, at *19 (“[w]ritten records which are, themselves, inconsistent, should be
accorded less deference than those which are internally consistent”) (quoting Murphy v. Sec’y of
Health & Human Servs., 23 Cl. Ct. 726, 733 (1991), aff'd per curiam, 968 F.2d 1226 (Fed. Cir.
1992)). Ultimately, a determination regarding a witness’s credibility is needed when determining
the weight that such testimony should be afforded. Andreu, 569 F.3d at 1379; Bradley v. Sec’y of
Health & Human Servs., 991 F.2d 1570, 1575 (Fed. Cir. 1993).

        When witness testimony is offered to overcome the presumption of accuracy afforded to
contemporaneous medical records, such testimony must be “consistent, clear, cogent, and
compelling.” Sanchez, 2013 WL 1880825, at *3 (citing Blutstein v. Sec’y of Health & Human
Servs., No. 90-2808V, 1998 WL 408611, at *5 (Fed. Cl. Spec. Mstr. June 30, 1998)). In
determining the accuracy and completeness of medical records, the Court of Federal Claims has
listed four possible explanations for inconsistencies between contemporaneously created medical
records and later testimony: (1) a person’s failure to recount to the medical professional
everything that happened during the relevant time period; (2) the medical professional’s failure
to document everything reported to her or him; (3) a person’s faulty recollection of the events
when presenting testimony; or (4) a person’s purposeful recounting of symptoms that did not
exist. La Londe v. Sec’y Health & Human Servs., 110 Fed. Cl. 184, 203-04 (2013), aff’d, 746
F.3d 1334 (Fed. Cir. 2014). In making a determination regarding whether to afford greater
weight to contemporaneous medical records over contrary testimony, there must be evidence that
this decision was the result of a rational determination. Burns, 3 F.3d at 417.

       D.      Analysis of Expert Testimony

        Establishing a sound and reliable medical theory often requires a petitioner to present
expert testimony in support of his claim. Lampe v. Sec’y of Health & Human Servs., 219 F.3d
1357, 1361 (Fed. Cir. 2000). Vaccine Program expert testimony is usually evaluated according to
the factors for analyzing scientific reliability set forth in Daubert v. Merrell Dow Pharm., Inc.,
509 U.S. 579, 594-96 (1993). See Cedillo v. Sec’y of Health & Human Servs., 617 F.3d 1328,
1339 (Fed. Cir. 2010) (citing Terran v. Sec’y of Health & Human Servs., 195 F.3d 1302, 1316
(Fed. Cir. 1999)). “The Daubert factors for analyzing the reliability of testimony are: (1) whether
a theory or technique can be (and has been) tested; (2) whether the theory or technique has been
subjected to peer review and publication; (3) whether there is a known or potential rate of error
and whether there are standards for controlling the error; and (4) whether the theory or technique
enjoys general acceptance within a relevant scientific community.” Terran, 195 F.3d at 1316 n.2
(citing Daubert, 509 U.S. at 592-95).

                                                22
        The Daubert factors play a slightly different role in Vaccine Program cases than they do
when applied in other federal judicial fora (such as the district courts). Daubert factors are
usually employed by judges (in the performance of their evidentiary gatekeeper roles) to exclude
evidence that is unreliable and/or could confuse a jury. In Vaccine Program cases, by contrast,
these factors are used in the weighing of the reliability of scientific evidence proffered. Davis v.
Sec’y of Health & Human Servs., 94 Fed. Cl. 53, 66-67 (2010) (“uniquely in this Circuit, the
Daubert factors have been employed also as an acceptable evidentiary-gauging tool with respect
to persuasiveness of expert testimony already admitted”). The flexible use of the Daubert factors
to evaluate the persuasiveness and reliability of expert testimony has routinely been upheld. See,
e.g., Snyder, 88 Fed. Cl. at 742-45. In this matter (as in numerous other Vaccine Program cases),
Daubert has not been employed at the threshold, to determine what evidence should be admitted,
but instead to determine whether expert testimony offered is reliable and/or persuasive.

        Respondent frequently offers one or more experts of his own in order to rebut a
petitioner’s case. Where both sides offer expert testimony, a special master’s decision may be
“based on the credibility of the experts and the relative persuasiveness of their competing
theories.” Broekelschen v. Sec’y of Health & Human Servs., 618 F.3d 1339, 1347 (Fed. Cir.
2010) (citing Lampe, 219 F.3d at 1362). However, nothing requires the acceptance of an expert’s
conclusion “connected to existing data only by the ipse dixit of the expert,” especially if “there is
simply too great an analytical gap between the data and the opinion proffered.” Snyder, 88 Fed.
Cl. at 743 (quoting Gen. Elec. Co. v. Joiner, 522 U.S. 146 (1997)); see also Isaac v. Sec’y of
Health & Human Servs., No. 08-601V, 2012 WL 3609993, at *17 (Fed. Cl. Spec. Mstr. July 30,
2012), mot. for review den’d, 108 Fed. Cl. 743 (2013), aff’d, 540 Fed. App’x 999 (Fed. Cir.
2013) (citing Cedillo, 617 F.3d at 1339).

       E.      Consideration of Medical Literature

        Both parties relied on a few pieces of medical and scientific literature in this case in
support of their respective positions. I have reviewed all of the medical literature submitted in
this case, although my decision does not discuss each filed article in detail. Moriarty v. Sec’y of
Health & Human Servs., No. 2015-5072, 2016 WL 1358616, at *5 (Fed. Cir. Apr. 6, 2016)
(“[w]e generally presume that a special master considered the relevant record evidence even
though he does not explicitly reference such evidence in his decision”) (citation omitted).

       F.      Determination to Resolve Case without Hearing

       I have opted to decide entitlement in this case based on written submissions and
evidentiary filings, including the expert reports filed by each side. The Vaccine Act and Rules
not only contemplate but encourage special masters to decide petitions on the papers rather than
via evidentiary hearing, where (in the exercise of their discretion) they conclude that the former

                                                 23
means of adjudication will properly and fairly resolve the case. Section 12(d)(2)(D); Vaccine
Rule 8(d). The choice to do so has been affirmed on appeal. See Hooker v. Sec’y of Health &
Human Servs., No. 02-472V, 2016 WL 3456435, at *21 n.19 (Fed. Cl. Spec. Mstr. May 19,
2016) (citing numerous cases where special masters decided on the papers in lieu of hearing and
that decision was upheld). I am simply not required to hold a hearing in every matter, no matter
the preferences of the parties. Hovey v. Sec’y of Health & Human Servs., 38 Fed. Cl. 397, 402-03
(1997) (special master acted within his discretion in denying evidentiary hearing); Burns, 3 F.3d
at 417; Murphy v. Sec’y of Health & Human Servs., No. 90-882V, 1991 WL 71500, at *2 (Ct. Cl.
Spec. Mstr. Apr. 19, 1991).

                                          ANALYSIS

        After careful review of the expert reports, medical records, and the arguments of both
sides, and taking into account my own experience resolving similar claims (as well as parallel
decisions from other Vaccine Act cases), I conclude that Petitioner has not established
preponderant evidence in favor of her claim.

       A.     Petitioner Has Not Shown that B.P. Had Any Mitochondrial Disease or
              Dysfunction.

        As I previously noted in R.V. v. Sec’y of Health & Human Servs., No. 08-504V, 2016 WL
3882519, at *26 (Fed. Cl. Spec. Mstr. Feb. 19, 2016), mot. for review den’d, 127 Fed. Cl. 136
(Fed. Cl. July 1, 2016), appeal dismissed, No. 16-2400 (Fed. Cir. Oct. 26, 2016), mitochondrial
disease or dysfunction includes a number of disorders affecting the body’s ability to metabolize
energy. It can manifest with a multitude of symptoms, including autism – although autism has
yet to be persuasively linked causally to the condition. Id. A true mitochondrial disease is
distinguishable from a lesser form of dysfunction; the former usually presents with severe,
clinically-recognized symptoms and is often conclusively diagnosed by genetic testing, while
mitochondrial dysfunction (also called “secondary” mitochondrial disease) can be the byproduct
of a different disease or merely reflect a transient problem. R.V., 2016 WL 3882519, at *26;
Anderson v. Sec’y of Health & Human Servs., No. 02-1314V, 2016 WL 8256278, at *24 (Fed.
Cl. Spec. Mstr. Nov. 1, 2016), mot. for review den’d, slip op., (Fed. Cl. Apr. 20, 2016). The
presence of mitochondrial dysfunction can be evaluated by consideration of the results of several
lab tests, applied to different diagnostic criteria. Cohen Rep. at 14; R.V., 2016 WL 3882519, at
*26.

       The facts of this case do not support a likely diagnosis of mitochondrial dysfunction or
disease, genetically-based or otherwise. As Dr. Cohen’s report summarized, the various lab tests
performed on B.P. not only confirmed that he did not have a prior mitochondrial disease (as best
evidenced by the negative genetic testing), but also did not confirm the existence of other


                                               24
biological markers that would be expected even if B.P. suffered from some lesser/secondary
form of mitochondrial dysfunction. Cohen Rep. at 13-19.

        Thus, analyte testing for serum lactate, blood amino acids, and urine organic acids levels
all produced results in the normal range. See, e.g., Ex. 11 at 2-5. Such testing can detect the
presence of an abnormal concentration of molecules, which may indicate mitochondrial
dysfunction – but it did not in this case. Cohen Rep. at 14. The few results that could reasonably
be characterized as abnormal, such as ketosis or an isolated blood lactate level, did not outweigh
the other normal results. See Ex. 17 at 1; Cohen Rep. at 15-17, 20.23 And other testing that could
have revealed neurologic injury reflective of an encephalopathy (such as an EEG and MRI
performed on B.P.) also produced normal results. Cohen Rep. at 15.

         Similarly, there is no evidence in the record of a genetically-based mitochondrial disease.
Ex. 35 at 5. B.P. underwent genetic karyotyping, chromosomal microarray, Fragile X, whole
exome sequence, and mitochondrial DNA testing – and all of these tests produced normal results.
Ex. 5 at 90, 113-16; Ex. 28 at 3; Ex. 30 at 1-2; Cohen Rep. at 17. Genetic tests for MECP2 and
congenital disorders of glycosylation were also negative. Ex. 17 at 1.24 And in any event, as Dr.
Cohen persuasively established in his report, had B.P. in fact possessed a genetically-derived
mitochondrial disease or dysfunction, the disease would most likely manifest by causing “death
in the first few years of life” – something that (thankfully) did not occur in this case. Id. at 18.

        The primary factual support Petitioner offered for the mitochondrial dysfunction
diagnosis is derived from the records of Drs. Frye and Kendall, and the opinions expressed
therein. But these materials provide weak support for Petitioner’s claim. Both of their
evaluations of B.P. were premised upon factually unsupported histories of regression following
vaccination provided by his parents, rather than a treater’s reasoned interpretation or evaluation
of the actual medical record. Cohen Rep. at 18-19; Ex. 17 at 1-2; Ex. 25 at 1-7. Dr. Kendall in
fact never even concluded that B.P. had some form of mitochondrial disease, but rather at best

23
   Such limited positive results were also not persuasive evidence of mitochondrial dysfunction for other reasons.
Thus, as Dr. Cohen stated (and unrebutted by Petitioner), ketosis is common after fasting and can be explained by
things like poor nutritional intake, making it too non-specific to give a positive result significant weight. Cohen Rep.
at 20; Ex. 46 at 2-5; Ex. 47 at 1-7. Likewise, a single abnormal blood lactate level, within a context of other normal
biochemical tests, cannot stand alone in establishing mitochondrial disease or dysfunction, since performing lactic
acid determinations, particularly in children with autism, can be difficult and often results in false positives. Cohen
Rep. at 15-17. Because of this, specialists experienced in diagnosing mitochondrial disease typically order
concomitant amino acid testing, which is more reliable evidence than an isolated elevation in blood lactate. Id. at 17.
Here, however, neither the blood amino acid testing nor urine organic acids testing in B.P. was suggestive of
mitochondrial dysfunction or disease. Id.
24
   As noted above, the only genetic testing result for B.P. that could support Petitioner’s theory was evidence of a
single heterozygous variant on the NRXN1 gene – but this finding is not clinically significant, since evidence of two
mutations would be required for the variants to produce mitochondrial dysfunction. See Ex. 20 at 1; Cohen Rep. at
17-18.


                                                          25
allowed that it was possible. Ex. 25 at 5. Two other treating physicians, Drs. Taravath and
Koeberl, were similarly reluctant to make that diagnosis. See Ex. 46 at 10; Ex. 16 at 8-9. Of
course, even where a treater expresses certainty that a particular diagnosis is correct, I need not
accept it, but may instead weigh it in the context of the overall treatment history. Snyder, 88 Fed.
Cl. at 746 n.67. Here, when such treater views are both equivocal and based on uncorroborated
medical histories, they merit even less evidentiary weight.

        The specific objective evidence that some of B.P.’s treaters used to conclude that he
likely had mitochondrial dysfunction is also insufficiently reliable. For example, Dr. Frye
appears to have relied on the buccal swab analysis to formulate his working diagnosis, but there
are several problems with relying on such a test, as Dr. Cohen persuasively established. See
Cohen Rep. at 16. In particular, the buccal swab analysis is only a research test, and therefore
even if its results in this case provide some support for the existence of a complex I deficiency, it
did not supply a recognized clinical criterion for the existence of mitochondrial dysfunction. Id.
at 16, 20-21. Certainly, without additional corroborative testing results, it cannot be relied upon
alone to establish preponderant evidence of mitochondrial dysfunction – and Petitioner offered
nothing from either of her experts that would rebut Dr. Cohen’s view of the overall validity of
this test. Nor has Petitioner offered medical literature that would bulwark the reliability of the
buccal swab analysis.

        The record also does not support the conclusion that B.P. suffered from an IgG deficiency
evidencing underlying mitochondrial dysfunction, as Dr. Harum proposed. Ex. 5 at 29. First, Dr.
Harum’s report never explained why an IgG deficiency would necessarily help establish the
existence of a metabolic disorder like mitochondrial disease. But even if she had, Dr. Roberts –
the Duke immunologist who evaluated B.P. – characterized B.P.’s IgG levels as only mildly low
and most likely due to transient causes, such as hypogammaglobulinemia of infancy. Ex. 23 at
11. After consideration of test results, Dr. Roberts concluded that B.P. had normal immunologic
function with no need for IVIG treatments intended to strengthen a deficient immune system. See
Ex. 23 at 7-12; Cohen Rep. at 13, 19. Petitioner has suggested no reason why I should find Dr.
Harum’s views more persuasive than Dr. Roberts’s – and after my own independent review of
the record, I conclude otherwise.

       There is also a lack of pre-vaccination evidence supporting Petitioner’s contention that
B.P. suffered from mitochondrial dysfunction. No treaters around the time of the relevant
vaccinations, or before, ever so proposed, and Petitioner and her experts do not reference any
other evidence suggesting that B.P. had a preexisting “subclinical” or “asymptomatic”
mitochondrial dysfunction. Kinsbourne Rep. at 3, 6. Accordingly, Petitioner has failed under
Loving prong one to establish that B.P.’s pre-vaccination condition included a genetic




                                                 26
susceptibility or subclinical mitochondrial dysfunction that was exacerbated by the relevant
vaccinations.25

        B.       B.P. Did Not Experience an Acute Post-Vaccination Reaction,
                 Regression, or Encephalopathy.

        The record in this case does not support another important factual component of
Petitioner’s case: that B.P. experienced an immediate reaction, encephalopathic in nature or
otherwise, after his fifteen-month-old vaccinations, characterized by a high fever and followed
by an observable loss of eye contact and speech as well as certain motor abilities. See Ex. 35 at 4.
It similarly does not suggest an immediate developmental regression as Petitioner alleges. To the
contrary – the medical records show no physical or developmental complaints at all in the
remaining seven months of 2011 following B.P.’s fifteen-month vaccinations in May.

        The earliest evidence of any kind from the medical records that any caregiver had
concerns about B.P.’s development are found in January 2012. See Ex. 3 at 19-21; Cohen Rep. at
19-20. And even at that time, there was no mention of regression. Rather, from May 2011 to the
end of that year, the pediatric records document normal development without any indication of
concerns of neurologic regression or abnormality. Ex. A at 21. There is a similar dearth of
evidence concerning the alleged encephalopathic event purportedly incited by the vaccinations as
described by Mrs. Pope. Petitioner cannot establish that such an event occurred simply based
upon her uncorroborated allegations – and especially where those after-the-fact allegations are
rebutted or unsupported by contemporaneous proof. Section 13(a)(1); Cucuras, 993 F.2d at
1528.26

25
   Petitioner has also failed to establish a concurrent (albeit less-emphasized) explanation for B.P.’s regression
and/or autism, as reflected in Dr. Harum’s report: that B.P. had an underlying immunological dysfunction that
impaired his ability to absorb the impact of his May 2011 vaccinations. Dr. Kinsbourne also proposes that B.P.’s
“vulnerability to infections” was attributable to a lowered level of immunoglobulin. See Kinsbourne Rep. at 3. A
core component of this aspect of the causation theory would be Dr. Harum’s supposition that B.P.’s low IgG levels
reflected immune dysregulation – but not only was her opinion rebutted more persuasively by Dr. Roberts’s view
(set forth in the medical records) that the low levels were transient and/or not uncommon, but by the fact that Dr.
Harum’s own treatment of those levels was ineffective – casting further doubt on the existence of an underlying
immunological dysfunction.
26
   It is instructive to compare the facts of this case with those exceedingly rare cases in which a claimant has
established an encephalopathy resulting in ASD-like symptoms (although both are also distinguishable because they
involved Table claims in which causation was assumed). In one such instance, the vaccinated child developed a very
high fever within 48 hours of vaccination, thereafter displaying crying, sleeplessness, and significant motor
problems, all of which were documented in the medical record. Poling v. Sec’y of Health & Human Servs., No. 02-
1466V, 2011 WL 678559, at *1 (Fed. Cl. Spec. Mstr. Jan. 28, 2011). In another, the vaccinated child received a
multi-virus vaccine and experienced a seizure on the trip home from the vaccination, followed by a week of
noticeably decreased levels of consciousness and lethargy. Wright v. Sec’y of Health & Human Servs., No. 12-423V,
2015 WL 6665600 (Fed. Cl. Spec. Mstr. Sept. 21, 2015). As discussed in R.V., an encephalopathy of this severity
would be required to prompt a drastic regression of the type Petitioner alleges. See R.V., 2016 WL 3882519, at *36.
In Petitioner’s case, by contrast, there are no records establishing any sort of proximate temporal reaction to the
vaccines that would support a finding that B.P. experienced such an encephalopathy.

                                                        27
        The subsequent records from 2012 provide little additional aid to Petitioner in this regard.
The initial evaluation and diagnosis by CDSA in July 2012 note no such history or regression,
and instead describe only a history of developmental delay. See Ex. 18; Cohen Rep. at 12. But
this is after several months passed without record evidence that the Popes or B.P.’s treaters
remained concerned about B.P.’s development. The records otherwise do not establish any
regression of skills in this period, as opposed to a cessation of development, and therefore (as Dr.
Cohen suggests) better support the conclusion that B.P.’s development problems were consistent
with the experience of children with idiopathic autism.

        In order to find that Petitioner had established her burden of proof with preponderant
evidence on this point, I would have to accept Petitioner’s personal recitation of the facts, along
with her explanation that treaters simply ignored her concerns and therefore did not record what
she told them. But to do so would fly in the face of the records, as well as existing legal tenets
for resolving disputes between contemporaneous medical records and after-the-fact witness
statements. Controlling law gives greater weight to the former, based on the reasonable
proposition that an individual would more likely than not tell a treater of an observed medical
problem or concern – and that in turn the treater (in the effort to provide the best care possible)
would note such concerns in the relevant record. Cucuras, 993 F.2d at 1528. It is too great a
factual leap, when the records fail to memorialize Mrs. Pope’s allegations that she informed
B.P.’s pediatricians about the onset of his developmental problems, to accept her assertion that at
every turn such treaters ignored her concerns, making those records untrustworthy.

       C.      Petitioner Has Not Established a Reliable or Persuasive Causation Theory.

         Petitioner’s theory – that the DTaP and PCV vaccines, separately or in concert, could
precipitate an encephalopathic event in a person with some degree of underlying mitochondrial
dysfunction, resulting in developmental regression and, eventually, an ASD diagnosis – lacks
reliability both in a specific and more general sense.

        With respect to the specific evidence offered in this case, neither of Petitioner’s expert
reports offers a trustworthy or persuasive opinion. Thus, as noted above, Dr. Harum’s report
simply repeats what is contained in the medical records, with little commentary or analysis. It
does not express an opinion as to the likelihood of the diagnoses at issue in this case, or set forth
a medical theory or logical sequence of cause and effect connecting any of B.P.’s vaccinations
with his subsequent condition. Because Dr. Harum was a treater, the fact that she was asked to
provide an expert opinion in this case gave her the opportunity to expand on why (as reflected in
the contemporaneous records) she assessed B.P. with encephalopathic regression into autism,
IgG deficiency, and/or mitochondrial insufficiency (see, e.g., Ex. 5 at 24-40; Ex. 7 at 1-3; Ex. 8
at 1-14) – yet she completely declines the opportunity to do so. I have given consideration to


                                                 28
what I take to be her views based on her treater status, and as reflected in the actual records – but
I do not find those views in this case merit significant weight.

        I also find that Dr. Harum’s treatment opinions about the nature of B.P.’s development
were based on unsubstantiated assumptions. For example, in both her initial evaluation and
subsequent report, Dr. Harum notes that Petitioner reported a dramatic change in B.P. after
fifteen months of age (the date she mistakenly27 assigned as the time B.P. had tubes placed in his
ears) – an assertion the record flatly rejects. Compare Harum Rep. at 3-4 with Ex. 3 at 33-37
(detailing normal 16- and 17-month check-ups). It appears she largely accepted the medical
history that Petitioner provided to her, without looking to see if the actual record corroborated it.
She also claims that Mrs. Pope’s allegations as to timing “are supported by evidence in the
Wilmington Health pediatric record, [her] examination and examination by the CDSA
developmental evaluation agency,” and that the observations during the CDSA evaluation on
July 19, 2012, “make a case for ongoing developmental regression.” Harum Rep. at 4-5. But
there are no such reports of regression contained in the contemporaneous WHC records or the
CDSA evaluation (which discuss developmental delay). See generally Exs. 3 and 18.28 An expert
opinion based on demonstrably false factual assumptions does not gain heft simply because it
comes from an expert; to the contrary, it loses persuasiveness and reliability if its factual
assumptions are false. See, e.g., Davis v. Sec’y of Health & Human Servs., 20 Cl. Ct. 168, 173
(1990); Raley v. Sec’y of Health & Human Servs., No. 91-732V, 1998 WL 681467, at *7 (Fed.
Cl. Spec. Mstr. Aug. 31, 1998) (“the conclusions of an expert are only as sound as their factual
predicate”).

       Dr. Kinsbourne’s opinion suffers from similar, facially-evident persuasiveness problems
stemming from unexamined factual assumptions that underlie his conclusions. Putting aside
legitimate questions surrounding his expertise to opine on the matters at issue,29 Dr.

27
  Thus, as noted above, Dr. Harum’s initial evaluation placed B.P.’s alleged regression as contemporaneous with his
tympanostomy tube placement at around fifteen months of age (Ex. 5 at 38), when in fact B.P. had his ear tubes
inserted in December 2010 (Ex. 3 at 49-51), when he was less than one year old.
28
   Dr. Harum’s opinion herein faces credibility problems similar to those that have arisen when she has offered an
opinion in other cases also alleging autism as a vaccine injury. Thus, in Fester v. Sec’y of Health & Human Servs.
No. 10-243V, 2016 WL 1745436 (Fed. Cl. Spec. Mstr. Apr. 7, 2016), Chief Special Master Dorsey specifically
decried a lack of a foundation as a reason for finding Dr. Harum’s opinions merited little weight. Fester, 2016 WL
1745436, at *15, 22. In Fester, Chief Special Master Dorsey ruled on the record that the petitioners were not entitled
to compensation for their claim that their child’s encephalopathy and/or autism was vaccine-caused. In so doing, the
chief special master noted that Dr. Harum’s opinion was based on “factual inaccuracies and medical presumptions
which are not supported by [the] medical records,” such as (a) that the child in question experienced regression post-
vaccination, and (b) that the child had some underlying condition that was exacerbated by a vaccine. Id. at *13-14,
24.
29
  As a pediatric neurologist, Dr. Kinsbourne has expertise in testifying about autism – but barely sufficient expertise
to opine on the interplay between vaccines and underlying metabolic deficiencies sufficient (after prompting by a
vaccine) to produce a neurologic injury like autism. He is also not an expert on the topic of mitochondrial disease –
the foundation of Petitioner’s theory.

                                                         29
Kinsbourne’s report places too much reliance on Petitioner’s allegations about B.P.’s condition
instead of the actual medical records. Indeed – he disregards the contemporaneous pediatric
records, which contradict Petitioner’s account, in forming his opinion in this case. See
Kinsbourne Rep. at 3. His opinion is thus premised on the demonstrably-incorrect assumption
that B.P. suffered a regression in temporal proximity to his fifteen-month vaccinations, a matter
he admits is critical to his opinion’s viability. Id. (“[w]hether the DTaP and Prevnar vaccinations
constitute the risk factor that transformed the disorder from a subclinical to a clinical level
depends in the first instance on when the autistic regression began.”).

        Beyond the above, Dr. Kinsbourne’s opinion is unpersuasive in providing reliable
scientific grounds supporting the conclusion that B.P.’s vaccinations could – and did – cause his
developmental delay. Dr. Kinsbourne clearly limits his opinion to a significant aggravation claim
alleging that the DTaP and PCV vaccines exacerbated B.P.’s preexisting asymptomatic
mitochondrial deficiency, resulting in his current autistic condition. In support of his general
theory, Dr. Kinsbourne associates autism with mitochondrial dysfunction by claiming that
“[c]hildren with autism are more likely to have mitochondrial dysfunction than typically
developing children.” Kinsbourne Rep. at 4.

       But this assertion finds minimal scientific support, at least based on literature filed in this
case. To the extent that he is relying on a single study (J. Shoffner et al., Fever Plus
Mitochondrial Disease Could Be Risk Factors for Autistic Regression, 25(4) J. Child Neurol. 429
(Jun. 2009) (filed as Ex. 64) ( “Shoffner”)), or case report (J. Poling et al., Developmental



 Dr. Kinsbourne has often testified in Vaccine Program cases on behalf of petitioners in a variety of contexts. See,
e.g., Hammitt v. Sec’y of Health & Human Servs., No. 07-170V, 2010 WL 3735705, at *8 (Fed. Cl. Spec. Mstr.
Aug. 31, 2010) (alleging that the petitioner’s DTaP vaccination caused her Dravet Syndrome), on reconsideration,
2011 WL 1135878 (Fed. Cl. Mar. 4, 2011), mot. for review den’d, 98 Fed. Cl. 719 (2011), aff’d, 676 F.3d 1373
(Fed. Cir. 2012). But other special masters have observed deficiencies in his capacity to opine on certain topics, due
in part to his lack of recent clinical expertise:

         A significant concern regarding Dr. Kinsbourne's reliability as an expert witness is that he has not
         maintained a “hospital based clinical pediatric neurology practice” since 1981. . . . Dr. Kinsbourne's
         testimony reflected his lack of recent clinical practice. His testimony was highly generalized and lacked
         any grounding in practice. While Dr. Kinsbourne may keep current with medical literature, . . . his
         testimony amounts to little more than repeating snippets from that literature.

         He has no current experience or context outside of “behavioral aspects” of pediatric neurology with which
         to apply, question, or discuss an article's teachings. . . . Dr. Kinsbourne does not publish, research, teach,
         counsel, attend meetings or conferences, or have any special training in the field of genetics. . . . Nor does
         Dr. Kinsbourne have any “experience or training or knowledge in clinical genetics, molecular genetics, and
         neurogenetics.” . . . The fact that for the past twenty-five years Dr. Kinsbourne has not focused his practice,
         research or teachings in the field of seizure disorders, and that Dr. Kinsbourne has no expertise in the field
         of genetics significantly limited his ability to offer reliable, persuasive, and cogent testimony in this case.

                                                          30
Regression and Mitochondrial Dysfunction in a Child with Autism, 21(2) J. Child Neurol. 170-72
(2006)) (filed as Ex. 63) (“Poling”) to bridge this analytical gap between vaccination and autism
(see Kinsbourne Rep. at 4-7), they fail to do so.

        Poling is a case report involving a single child later diagnosed with mitochondrial
disease. The child had received several vaccinations, and then within 48 hours developed a high
fever that became low-grade over the next several days, along with inconsolable crying,
sleeplessness, and significant, noticeable motor problems that worsened over the next several
days. Poling at 1. There, not only was the mitochondrial disease diagnosis supported, but the
reaction to the vaccines was facially undeniable – unlike in this case.

       Shoffner, while a legitimate piece of scientific literature, is also unhelpful given the
present facts. That study looked at the relationship between autistic regression in patients with
mitochondrial dysfunction and fever – not vaccination and fever and/or autism. Shoffner at 1.
Indeed, as Shoffner succinctly acknowledges, “[a]utistic regression was not associated with
vaccination.” Shoffner at 3, 4 (“[i]n our patients with mitochondrial disease and autistic spectrum
disorders, the vaccines did not appear related to the neurologic regression.”). Shoffner cannot be
put to work on behalf of Petitioner’s theory in the way she attempts – especially when B.P. did
not even experience a fever after the May 2011 vaccinations (at least based on the medical
records), where there is no medical record support for the conclusion that he experienced
developmental regression, and where his developmental problems in fact took months thereafter
to manifest.30

        Dr. Kinsbourne’s opinion was otherwise persuasively rebutted. As Dr. Cohen aptly
explained in response, “[a]lthough autism can be seen in children who also have mitochondrial
disorders, the two have not been causatively linked and those children either have additional
clinical features or diagnostic biochemical-genetic-histological features that extend beyond the
autism diagnosis,” which were not present in B.P.’s case. Cohen Rep. at 14. Petitioner has
offered nothing in response. And (in contrast to both Drs. Kinsbourne and Harum) Dr. Cohen has
demonstrably superior expertise in the field of mitochondrial disease. This, along with the
comprehensive and detailed character of his expert report, led me to give his opinions greater
weight than Dr. Kinsbourne’s on these matters.31

30
  Additionally, the Federal Circuit’s decision in Paluck does not compel a finding that Dr. Kinsbourne’s causation
theory here is legally sufficient to meet Petitioner’s burden, whether under the first Althen prong or fourth Loving
prong. Besides involving far more extreme facts than herein, in Paluck the Federal Circuit made no findings
whatsoever with respect to the reliability of the petitioners’ medical theory – nor was it asked to on appeal. By
contrast, there are numerous apposite cases where the reliability of the medical theory connecting autism to
mitochondrial disease has been successfully challenged. See, e.g., Bast, 2012 WL 6858040, at *25-39. Accordingly,
the results in a single outlier case like Paluck provide no persuasive grounds for a similar determination herein.
31
  Because Mrs. Pope cannot establish that B.P. suffered from the underlying mitochondrial disorder so integral to
her causation theory, coupled with the facial weaknesses of her expert reports, I need not engage in a full Althen

                                                        31
       Besides such problems with the expert opinions specifically offered in this case, however,
Mrs. Pope’s theory had a more general credibility problem. Petitioner relies on a causation
theory that has been universally rejected when raised in prior Vaccine Program cases. To date,
every non-Table claim litigated since completion of the Omnibus Autism Proceeding32 seeking
compensation for autism injuries purportedly related to a vaccine has failed. See, e.g., Hardy v.
Sec’y of Health & Human Servs., No. 08-108V, 2015 WL 7732603, at *4-5 (Fed. Cl. Spec. Mstr.




analysis herein. See, e.g., Lasnetski v. Sec’y of Health & Human Servs., 128 Fed. Cl. 242, 264 (2016) (not error for
special master to forgo Althen analysis after determining that a petitioner had not in fact experienced the disease or
illness alleged to have been vaccine-caused), citing Hibbard, 698 F.3d at 1365. However, Petitioner has also failed
to establish the third Althen prong of a medically acceptable timeframe. The only evidence offered to support a
proximate temporal relationship in this case is set forth in a brief paragraph in Dr. Kinsbourne’s report, where he
proposes, conclusorily, that B.P.’s “autistic disorder originated within a medically reasonable temporal relationship
to the two vaccinations.” Kinsbourne Rep. at 6. Citing Shoffner, Dr. Kinsbourne alleges that “any mitochondrial
reaction to an infection or vaccination typically becomes evident by two weeks after the provocative event.” Id.
However, as explained above, Shoffner looked only at the relationship between autistic regression and fever, not
regression after vaccination, and thus does not stand for the proposition for which it has been cited. Moreover, the
medical records do not establish that B.P. suffered from a fever in connection with his fifteen-month vaccinations,
that his developmental problems began not long after the vaccinations, or that he experienced regression as opposed
to developmental delay.
32
  In the Omnibus Autism Proceeding (“OAP”), thousands of petitioners’ claims that certain vaccines caused autism
were joined for purposes of efficient resolution. A “Petitioners’ Steering Committee” was formed by many attorneys
who represent Vaccine Program petitioners, with about 180 attorneys participating. This group chose “test” cases to
represent the entire docket in the OAP, with the understanding that the outcomes in these cases would be applied to
cases with similar facts alleging similar theories.

  The Petitioners’ Steering Committee ultimately chose six test cases to present two different theories regarding
autism causation. The first theory alleged that the measles portion of the MMR vaccine precipitated autism, or, in
the alternative, that MMR plus thimerosal-containing vaccines caused autism, while the second theory alleged that
the mercury contained in thimerosal-containing vaccines could affect an infant’s brain, leading to autism.

 The first theory was rejected in three test case decisions, all of which were subsequently affirmed. See generally
Cedillo v. Sec’y of Health & Human Servs., No. 98-916V, 2009 WL 331968 (Fed. Cl. Spec. Mstr. Feb. 12, 2009),
mot. for review den’d, 89 Fed. Cl. 158 (2009), aff’d, 617 F.3d 1328 (Fed. Cir. 2010); Hazlehurst v. Sec’y of Health
& Human Servs., No. 03-654V, 2009 WL 332306 (Fed. Cl. Spec. Mstr. Feb. 12, 2009), mot. for review den’d, 88
Fed. Cl. 473 (2009), aff’d, 605 F.3d 1343 (Fed. Cir. 2010); Snyder v. Sec’y of Health & Human Servs., No. 01-
162V, 2009 WL 332044 (Fed. Cl. Spec. Mstr. Feb. 12, 2009), aff’d, 88 Fed. Cl. 706 (2009).

 The second theory was similarly rejected. Dwyer v. Sec’y of Health & Human Servs., No. 03-1202V, 2010 WL
892250 (Fed. Cl. Spec. Mstr. Mar. 12, 2010); King v. Sec’y of Health & Human Servs., No. 03-584V, 2010 WL
892296 (Fed. Cl. Spec. Mstr. Mar. 12, 2010); Mead v. Sec’y of Health & Human Servs., No. 03-215V, 2010 WL
892248 (Fed. Cl. Spec. Mstr. Mar. 12, 2010).

 After the OAP’s conclusion, a total of 11 lengthy decisions by special masters, the judges of the U.S. Court of
Federal Claims, and the panels of the U.S. Court of Appeals for the Federal Circuit had unanimously rejected the
petitioners’ claims. These decisions found no persuasive evidence that the MMR vaccine or thimerosal-containing
vaccines caused autism. The OAP proceedings concluded in 2010.

Nov. 3, 2015) (referencing eleven autism claims unsuccessfully tried, plus six that were rejected
(over the petitioners’ objections) without trial).33

        The same result has occurred in those cases where – like Petitioner herein – claimants
assert that a child’s underlying metabolic disorder (most commonly a mitochondrial disease of
some kind) was exacerbated by a vaccine, resulting in a developmental regression or autism. See,
e.g., Hardy, 2015 WL 7732603, at *4-5 (petitioners failed to demonstrate that DTaP vaccine
caused or significantly aggravated underlying mitochondrial disease resulting in ASD); R.V.,
2016 WL 3882519, at *42, mot. for review den’d, 127 Fed. Cl. 136 (2016) (factual record did not
support contention that child suffered from a mitochondrial disease, or that the vaccine at issue
had a causal connection to the development of ASD); Miller v. Sec’y of Health & Human Servs.,
No. 02-235V, 2015 WL 5456093 (Fed. Cl. Spec. Mstr. Aug. 18, 2015) (petitioners failed to
demonstrate that several childhood vaccines caused encephalopathy or aggravated underlying
mitochondrial disease/dysfunction); Lehner v. Sec’y of Health & Human Servs., No. 08-554V,
2015 WL 5443461 (Fed. Cl. Spec. Mstr. July 22, 2015) (petitioners failed to demonstrate that flu
vaccine resulted in autoimmune encephalitis). The theory as presented in this case was no more
compelling than the different iterations offered in the aforementioned cases.

        Perhaps aware of the steep odds of prevailing, other petitioners have attempted to recast
their claim that a vaccine caused an autism injury as a claim that the vaccine precipitated some
form of encephalopathy (more often than not autoimmune in nature) that later produced
developmental problems due to the resulting neurologic injury. See, e.g., Cunningham v. Sec’y of
Health & Human Servs., No. 13-483V, 2016 WL 4529530 (Fed. Cl. Spec. Mstr. Aug. 1, 2016),
mot. for review den’d, slip op. (Fed. Cl. Jan. 25, 2017). But such efforts have been correctly
understood as seeking to evade the weight of negative precedent involving autism claims – as
here. Cunningham, slip op. at *7-8 (“[r]egardless of petitioner’s attempt to differentiate this case
from other autism cases by creating this second step, the Special Master rightfully classified this
case as an autism case”).

         D.       Althen Analysis.

        Give the above, it is evident that Petitioner has not met her burden under the analysis set
forth in Althen for proving a causation-in-fact claim.

33
   In a single instance, petitioners (the parents of a vaccinated child) successfully established a Table injury – an
encephalopathy – after vaccination that resulted in an autistic-like developmental regression. See, e.g., Wright, 2015
WL 6665600. In Wright, the petitioners met the Table criteria for an “acute encephalopathy” following vaccination
by establishing by preponderant evidence that the vaccinated child experienced a seizure followed by loss of
consciousness shortly after receipt of a pertussis-containing vaccine; the severe reaction lasted for more than 24
hours, with resulting demonstrable significant changes in behavior. But the special master responsible for that
decision (former Chief Special Master Vowell) explicitly noted in her decision that the petitioners would not have
been able to establish entitlement under their non-Table claim, because their expert presented a causation opinion
that she found “absurd and biologically impossible.” Wright, 2015 WL 6665600, at *2.

                                                         33
       Prong One

       As already noted, Mrs. Pope has failed to offer a reliable medical or scientific theory
explaining how the DTaP or PCV vaccines could aggravate an underlying mitochondrial disease
or lesser disorder, causing regression or other developmental injuries. Her experts were
unpersuasive and unable to advance a reliable medical theory to support her claim, while
Respondent’s expert credibly rebutted the concept that an underlying mitochondrial disorder
could be so affected by the relevant vaccines to initiate a process manifesting eventually as an
ASD. Petitioner’s general theory is also barely distinguishable from those that have been
repeatedly advanced but rejected in the Program.

       Prong Two

        Petitioner’s obligation under the second Althen prong was to demonstrate a logical
sequence of cause and effect connecting the particular facts of her case to her medical theory.
See, e.g., Sturdivant v. Sec’y of Health & Human Servs., No. 07-788V, 2016 WL 552529, at *18
(Fed. Cl. Spec. Mstr. Jan. 21, 2016) (discussing that prong two requires a fact-based inquiry into
whether the vaccine in question did cause the particular injury). But her theory depended on
acceptance of her allegation that B.P. suffered from a mitochondrial disease or dysfunction – a
conclusion the record does not support. Treater opinions that seemed to bulwark the theory
proved unreliable, as they were based on unsupported factual histories recounted by B.P.’s
parents, rather than independent review of the medical records. In addition, the medical record
was bereft of reliable evidence that B.P. experienced an immediate reaction, encephalopathy, or
regression following his fifteen-month-old vaccinations, despite the after-the-fact assertions of
Mrs. Pope to the contrary.

       Prong Three

        Even if I had accepted Mrs. Pope’s showing in support of her theory, B.P.’s injuries have
not been shown to have occurred within a medically appropriate timeframe. Dr. Kinsbourne
proposed that mitochondrial reactions to vaccinations become evident within two weeks after the
triggering event. Kinsbourne Rep. at 6. Yet there were no contemporaneous references in the
medical records supporting Petitioner’s allegation that B.P. began exhibiting any different
behavior or reaction to the vaccinations at issue within two weeks. In fact, there are no
developmental concerns noted until January 2012, eight months following vaccination. This is
simply too far removed from the vaccination to suggest a causal relationship, and Petitioner has
provided no convincing evidence otherwise.

       E.      This Case was Properly Resolved without a Hearing.


                                               34
       In ruling on the record, I am declining Petitioner’s request that I conduct a hearing. The
choice of how best to resolve this case is a matter that lies generally within my discretion, but
given Petitioner’s protestations I shall explain my reasoning.

        A hearing provides a petitioner with the opportunity to put on live testimony, which aids
the special master most in cases where witness credibility is at issue or where there is a need to
pose questions to a witness in order to obtain information not contained in, or not self-evident
from, the existing filings. See, e.g., Hooker, 2016 WL 3456435, at *21 (discussing a special
master’s discretion in holding a hearing and the factors that weighed against holding a hearing in
the matter); Murphy, 1991 WL 71500, at *2 (no justification for a hearing where the claim is
fully developed in the written records and the special master does not need to observe the fact
witnesses for the purpose of assessing credibility). It may also permit a claimant to expand upon
or illuminate points already set forth in paper filings, or respond to unanticipated questions raised
in the matter – but again, only where necessary to reach a decision.

        Prior decisions have recognized that a special master’s discretion in deciding whether to
conduct an evidentiary hearing “is tempered by Vaccine Rule 3(b),” or the duty to “afford[] each
party a full and fair opportunity to present its case.” Hovey, 38 Fed. Cl. at 400-01 (citing Rule
3(b)). But that rule also includes the obligation of creation of a record “sufficient to allow review
of the special master’s decision.” Id. Thus, the fact that a claim is legitimately disputed, such that
the special master must exercise his intellectual faculties in order to decide a matter, is not itself
grounds for a trial (for if it were, trials would be required in every disputed case). Special
masters are expressly empowered to resolve fact disputes without a hearing.34

       In this case, live witness testimony was not required in order for me to reach a reasoned
decision. The record itself was expansive and contained sufficient evidence upon which to base
this decision. The flaws in Petitioner’s theory and factual arguments were self-evident from
review of the medical records and the two expert reports submitted, both of which relied heavily

34
   I therefore do not find persuasive Petitioner’s argument that Respondent’s motion is akin to one for summary
judgment that cannot be granted because “disputed issues of material fact” have been raised. Opp. at 16. Petitioner
has unquestionably contested certain facts, such as whether B.P. experienced regression, or some kind of severe
physiologic reaction, after the May 2011 vaccinations. But in inviting the parties to brief the case on the papers, I
was signaling my preliminary assessment that (given the facts at issue, as well as the nature of the causation theory)
Petitioner was not likely to succeed in this case. That determination in turn was based upon two conclusions. First,
the factual disputes were not sufficiently material to warrant hearing (since materiality of disputed fact issues bears
heavily on when summary judgment should be granted (see, e.g., Anderson v. Liberty Lobby, Inc., 477 U.S. 242, 248
(1986) (“only disputes over facts that might affect the outcome of the suit under the governing law will properly
preclude the entry of summary judgment”)). Second, Petitioner did not reasonably contest certain facts (i.e., by
gainsaying the medical records, which provided no corroboration for Mrs. Pope’s assertions about what she
observed was occurring to B.P. at certain points in time). It is not enough to invoke summary judgment
jurisprudential considerations as a basis for holding a hearing by asserting “I object,” if that objection lacks
evidentiary foundation.


                                                         35
on witness statements that were uncorroborated by, or contrary to, the contemporaneous medical
record. And, as noted above, Petitioner’s experts offer opinions that are scientifically unreliable
and unpersuasive, while also consistent with opinions repeatedly rejected in the Program. Such
deficiencies did not require oral testimony to be understood for purposes of deciding the case. On
the contrary: the congruence of the theory espoused herein with numerous, previously-rejected
variations on the same theme counseled against expending the time and effort necessary for a
hearing.35

        I similarly did not need to hear directly from Petitioner or her family members about the
precise timing of the onset of B.P.’s reactions or alleged regression. There are many cases where
witness testimony about the nature of a symptom or its onset is critical to determining a fact
issue. See, e.g., Rich v. Sec’y of Health & Human Servs., No. 12-742V, 2015 WL 5882324 (Fed.
Cl. Spec. Mstr. Sept. 16, 2016) (fact hearing required witness testimony to determine onset of
petitioner’s ADEM symptoms); Reddy v. Sec’y of Health & Human Servs., No. 13-208V, 2015
WL 5578610 (Fed. Cl. Spec. Mstr. Aug. 26, 2015) (determining onset of symptoms through
witness testimony at fact hearing to resolve whether claim was timely filed); Bray v. Sec’y of
Health & Human Servs., No. 10-207V, 2014 WL 5025173 (Fed. Cl. Spec. Mstr. Sept. 16, 2014)
(requiring witness testimony to determine if petitioner received the flu vaccine). In such
instances, it may be necessary to evaluate the witness’s demeanor live in order to determine how
much weight to give a factual allegation.

        But here, I can dispense with live testimony, which was uncorroborated by the existing
medical record. The record overwhelmingly does not support the conclusion that B.P.’s
developmental problems began any time before late 2011. Mrs. Pope cannot prevail in a Vaccine
Act claim simply based upon her own allegations. Where, in a case like this, the petitioner’s
onset allegations that a child had begun experiencing developmental decline or delay –
conditions that a parent would more likely than not share with a treater – find no support in the
record, I need not hear from the parent directly to find that the testimony (however heartfelt or in
good faith) is less trustworthy than the contemporaneous written evidence.

        I also did not require hearing from the experts directly. Both of Petitioner’s experts were
facially less qualified to testify on the matters in dispute than Dr. Cohen, giving me greater
reason to weigh his opinions over theirs. Moreover, the deficiencies in Petitioner’s experts’
opinions were self-evident simply from reading them. Expert reports are intended to provide a
written statement of the expert’s actual opinion – not a tease of positions or views the expert may
provide at hearing, thereby leaving their true opinions a surprise that will only be revealed at

35
   The decision not to hold a hearing because the claim reflected a frequently-litigated theory is not something that
would only ever negatively impact a petitioner. The opposite circumstances – where a petitioner asserted a claim
that has repeatedly succeeded in the past (for example, the allegation that the flu vaccine can cause Guillain-Barré
syndrome) – would motivate me to act in the same manner, and propose to Respondent that either the case be settled
or that it be resolved on the papers.

                                                        36
trial. I knew enough about the problems with Petitioner’s experts based on the existing record to
rule on this matter without hearing from them live.

        At bottom, the most significant issue in deciding whether to hold a hearing is determining
if the refusal to do so will deprive the claimant of the fair opportunity to prosecute her case.
Petitioner here has received such an opportunity. Her chances of winning would not have
increased merely because her claim was litigated in court. Indeed, as the procedural history
indicates, she was given ample extensions of time to obtain Drs. Harum’s and Kinsbourne’s
reports, and to marshal the arguments she made in opposing Respondent’s motion on the record.
In addition, she and her counsel are on reasonable notice of the difficulties they would face in
attempting to prove an autism injury in the Vaccine Program, in light of the many negative
decisions cited above that are directly relevant to her claim given the similarities of their facts as
well as the causation theories attempted. Regardless of Petitioner’s hopes, a hearing would not
have changed the outcome, but would have unnecessarily postponed the date by which the matter
could be fully resolved. Such circumstances ultimately counseled in favor of resolving the matter
on the papers.


                                              CONCLUSION

        The record does not support Mrs. Pope’s contention that the vaccines B.P. received
could, or did, cause his developmental regression or autism, nor has she established it more
likely than not that he suffered from some form of underlying mitochondrial dysfunction.
Petitioner has not established entitlement to a damages award, and therefore I must DISMISS
her claim.

Court), the Clerk shall enter judgment in accordance with this decision.36
