                                              DECISION1

Vowell, Chief Special Master:

       On January 7, 2003, Thomas and Pamela Blake [“petitioners”] filed a petition for
vaccine injury compensation under the National Childhood Vaccine Injury Act2 [“Vaccine
Act”] on behalf of their son, W.J.B. Petitioners alleged that the vaccines W.J.B.
received on December 13, 1999 and January 4, 2000 caused an “encephalopathic
pattern of change characteristic of the autism spectrum.” Petition at 1. Petitioners also

  This decision will be posted on the United States Court of Federal Claims' website, in accordance with
the E-Government Act of 2002, Pub. L. No. 107-347, § 205, 116 Stat. 2899, 2913 (codified as amended
at 44 U.S.C. § 3501 note (2006)). In accordance with Vaccine Rule 18(b), a party has 14 days to identify
and move to redact medical or other information, that satisfies the criteria in 42 U.S.C. § 300aa-
12(d)(4)(B). If, upon review, I agree that the identified material fits within the requirements of that
provision, I will redact such material from public access.

 The National Vaccine Injury Compensation Program [“Program”] comprises Part 2 of the National
Childhood Vaccine Injury Act of 1986, Pub. L. No. 99-660, 100 Stat. 3755, codified as amended, 42
U.S.C.A. §§ 300aa-10 et seq. (2006). All citations to the Vaccine Act in the decision will be to 42 U.S.C. §
300aa.

contended “that [W.J.B.] suffered mercury poisoning which was caused-in-fact by the
thimerosal present in the vaccines he received since birth.” Id., ¶ 17.

        On September 14, 2011, petitioners filed an amended petition, alleging that
W.J.B. suffered “the table injury known as encephalopathy” after receiving the measles,
mumps, and rubella [“MMR”] vaccine on January 4, 2000. Amended Petition [“Am.
Petition”] at 1. The amended petition now constitutes the operative petition for
petitioners’ vaccine injury claim. However, in their motion for a ruling on the record
petitioners also asserted that the MMR vaccine actually caused W.J.B.’s injuries.3 I will
treat these assertions as raising a causation in fact claim and, thus, this decision also
resolves any off-Table (actual causation) injury claim petitioners have made.

        The case is now ripe for a decision. In order to prevail under the Program,
petitioners must prove either that W.J.B. sustained a “Table” injury4 or that a vaccine
listed on the Table was the cause in fact of an injury. The record as a whole fails to
demonstrate that W.J.B. suffered a Table injury or that a vaccine caused his autism
spectrum disorder.5 Petitioners’ vaccine injury claims are therefore dismissed.

                                       I. Procedural History.

       A month after petitioners filed their original petition, their claim was, without
objection, included in the Omnibus Autism Proceeding [“OAP”].6 Their case was



3
  Petitioners argued both a Table Injury claim and actual causation claim in their motion for a decision on
the record and reply. See Petitioners’ Motion for a Decision on the Record [“Pet. Motion”] at 1 (asserting
that they had established a “prima facie case” that W.J.B.’s encephalopathy was caused by the MMR
vaccination); Petitioners’ Reply in Support of Pet. Motion [“Pet. Reply”] at 3-4 (arguing that they proved
W.J.B.’s encephalopathy was caused by the MMR vaccine); Petitioners’ Statement of Proposed Findings
of Fact [“Pet. Facts”] at 2-3 (proposed statement of facts including that physicians had opined that
W.J.B.’s encephalopathy was causally and temporally connected to the MMR vaccination); see also
Petitioners’ Memorandum in Support of Motion for Decision on the Record [“Pet. Memo”] at 6
(commenting that a physician had opined that it was more probable than not that the MMR vaccine
caused W.J.B.’s encephalopathy). As proof of causation is unnecessary if the factual requirements for a
Table injury have been established, I have elected to treat these assertions as raising a causation in fact
claim.
4
 A “Table” injury is an injury listed on the Vaccine Injury Table, 42 C.F.R. § 100.3, corresponding to the
vaccine received within the time frame specified.
5
  Pervasive developmental disorder [“PDD”] was the umbrella term for autism spectrum disorders used in
the Diagnostic and Statistical Manual of Mental Disorders (American Psychiatric Association, 4th ed. text
revision 2000) [“DSM-IV-TR”]. The DSM-IV-TR has since been replaced by the Diagnostic and Statistical
Manual of Mental Disorders (American Psychiatric Association, 5th ed. 2013) [“DSM-V”] which uses the
term “autism spectrum disorder” [“ASD”].

 See Notice, issued Feb. 10, 2003. A more detailed discussion of the OAP can be found at Dwyer v.
Sec’y, HHS, No. 03-1202V, 2010 WL 892250, at *3 (Fed. Cl. Spec. Mstr. Mar. 12, 2010).

effectively stayed while general causation issues were litigated in the OAP test cases.7

        During the period between the test case hearings and final appellate action in the
test cases, petitioners were ordered to file the medical records necessary to establish
that the petition was timely filed. Order, issued Apr. 15, 2008, at 2-5. After petitioners
filed medical records on July 11, 2008, as Petitioners’ Exhibits [“Pet. Exs.”] 1-13,
respondent filed a statement acknowledging that the claim was timely filed and the
injury involved an autism spectrum disorder. Respondent’s Statement, filed Aug. 25,
2008, at 3. Following resolution of the OAP test cases,8 petitioners opted to continue
their claim.

         On October 5, 2011, the special master formerly assigned to the case 9 held a
conference call with the parties to discuss the amended petition. See Order, issued
Oct. 5, 2011, at 1. During the call, the special master referenced the definition of acute
encephalopathy contained in the Qualifications and Aids to Interpretation [“QAI”] section
of the Vaccine Injury Table (see 42 C.F.R. § 100.3(b)(2)(i))10 and noted the “potential
difficulty associated with characterizing symptoms that commonly manifest as
symptoms of autism as symptoms that are indicative of an acute encephalopathy.”
Order, issued Oct. 5, 2011, at 1.

         In a status report filed on November 3, 2011, petitioners indicated they planned
to file an expert report from W.J.B.’s treating physician Dr. Gerald Erenberg, a pediatric
and adolescent neurologist, and a second expert report from an “independent” medical


7
 The Petitioners’ Steering Committee [“PSC”], an organization formed by attorneys representing
petitioners in the OAP, litigated six test cases presenting two different theories on the causation of autism
spectrum disorder [“ASDs”]. Petitioners’ original claim fell within the second theory of causation [“Theory
2”] litigated in the OAP. Their causation in fact claim implicates the first causation theory [“Theory 1”]
advanced in the OAP test cases.
8
 Decisions in each of the three test cases pertaining to the PSC’s first theory rejected petitioners’
causation theories. Cedillo v. Sec’y, HHS, No. 98-916V, 2009 WL 331968 (Fed. Cl. Spec. Mstr. Feb. 12,
2009), aff’d, 89 Fed. Cl. 158 (2009), aff’d, 617 F.3d 1328 (Fed. Cir. 2010); Hazlehurst v. Sec’y, HHS, No.
03-654V, 2009 WL 332306 (Fed. Cl. Spec. Mstr. Feb. 12, 2009), aff’d, 88 Fed. Cl. 473 (2009), aff’d, 604
F.3d 1343 (Fed. Cir. 2010); Snyder v. Sec’y, HHS, No. 01-162V, 2009 WL 332044 (Fed. Cl. Spec. Mstr.
Feb. 12, 2009), aff’d, 88 Fed. Cl. 706 (2009). Decisions in each of the three “test cases” pertaining to the
PSC’s second theory also rejected the causation theories, and petitioners in each of the three cases
chose not to appeal. Dwyer, 2010 WL 892250; King v. Sec’y, HHS, No. 03-584V, 2010 WL 892296 (Fed.
Cl. Spec. Mstr. Mar. 12, 2010); Mead v. Sec’y, HHS, No. 03-215V, 2010 WL 892248 (Fed. Cl. Spec. Mstr.
Mar. 12, 2010).

 This case was formerly assigned to Chief Special Master Campbell-Smith. Prior to her appointment as
Judge of the United States Court of Federal Claims, the case was reassigned to me. President Obama

  The QAI to the Vaccine Injury Table are located at 42 C.F.R. § 100.3(b) and contain definitions for the
terms used in the Table. See Althen v. Sec’y, HHS, 58 Fed. Cl. 270, 280 (2005), aff’d, 418 F.3d 1274
(Fed. Cir. 2005) (noting that the QAI should be used to interpret key terms found in the Table).

expert, Dr. Stephanie F. Cave,11 a family practice physician. Status Report at 1.
Petitioners never filed an expert report from Dr. Erenberg, but did file Dr. Cave’s expert
report on November 30, 2011.

       Due to “a lack of documentary support for the factual allegations” in Dr. Cave’s
report, the special master ordered petitioners to file a supplemental report, referencing
the exhibit and page number of records supporting her factual assertions and including
details regarding her “relevant training and professional experiences.” Order, issued
Dec. 12, 2011, at 1, n.1. Petitioners filed Dr. Cave’s supplemental expert report on
January 16, 2012, as Pet. Ex. 15.12

        In a lengthy order issued on February 15, 2012, the special master discussed Dr.
Cave’s lack of expertise in the relevant specialties of developmental pediatrics, pediatric
neurology, or pediatric immunology, and the lack of evidence of a Table
encephalopathy. Order at 1-4. She observed that “the symptoms of concern seem to
be completely consistent with the early symptoms of autism.” Id. at 6. She indicated
that “[a]t present, the factual record and Dr. Cave’s expert report fall short of
establishing that [W.J.B.] suffered a MMR vaccine-related encephalopathy as defined
by the Vaccine Injury Table” and questioned the reasonableness of moving forward on
that theory. Id. at 7.

         Notwithstanding the special master’s concerns, petitioners reiterated that they
wished to continue their claim. Status Report, filed Mar. 16, 2012. Following some
difficulty in communication between petitioners and their attorney (see Order to Show
Cause, issued July 10, 2012), a fact hearing was set for November 14, 2012 (Order,
issued Sept. 13, 2012).

        Only petitioners testified at the hearing, but affidavits from Mrs. Blake’s sister,
Debbie Knopf, and W.J.B.’s great aunt, Patricia Blake, were filed as Pet. Exs. 25-26.
Prior to the hearing, petitioners also filed their joint affidavit (Pet. Ex. 14), pages from a
journal kept by petitioners (Pet. Ex. 16), two videos of W.J.B. (Pet. Exs. 18A and 18B),13
notes describing the video clips (Pet. Ex. 17),14 photographs of W.J.B. (Pet. Ex. 19),

  Doctor Cave is the mother of petitioners’ counsel, Michael Cave. See Mooney v. Sec’y, HHS, No. 05-
266V, 2013 WL 3874444, at *3, 4 n.14 (Fed. Cl. Spec. Mstr. July 3, 2013).
12
   Petitioners did not assign an exhibit number to Dr. Cave’s initial expert report. However, the
supplemental report is virtually identical to the initial report, other than the addition of paragraph 2 and
citations to medical records. All citations to Dr. Cave’s report are to the supplemental version filed as Pet.
Ex. 15.
13
  Petitioners filed the first video, labeled as Pet. Ex. 18, on October 4, 2012. The docket does not
indicate exactly when the second video was received by the court but a notice indicating the video was
mailed was electronically filed on November 5, 2012. Although the second video was labeled as Pet. Ex.
18, Part 2, I will refer to the first video as Pet. Ex. 18A and second video as Pet. Ex. 18B.

     Petitioners provided handwritten notes (Pet. Ex. 17), ostensibly describing what the video clips

27). Respondent’s counsel indicated he would not be calling any witnesses.
Respondent’s Pre-Hearing Submission, filed Oct. 3, 2012, at 1.

       In a post hearing status conference, the special master discussed her
impressions with the parties and issued a lengthy order summarizing the matters
discussed. See Order, issued Jan. 23, 2013. She indicated that she was “prepared to
accept as true, the claim that [W.J.B.] exhibited startles that may have been seizure-
related during the occasion of the family meal” on January 9, 2000. Id. at 2.
Nevertheless, she concluded that there was insufficient evidence to demonstrate that
W.J.B. had experienced a Table encephalopathy.16 Id. Informing the parties that she
“consider[ed] the record to be factually complete, and amenable to a summary judgment
motion,” the special master urged petitioners to file a motion for a decision, explaining
they could file a motion for a decision on the record, in which they could include a
proposed set of facts, or a motion to dismiss their claim. Id. at 3.

        The case was reassigned to me on March 8, 2013. On April 4, 2013, petitioners
filed a motion for a decision on the record, along with several supporting memoranda.17
Approximately six weeks later, respondent filed her response, along with two medical
journal articles on the symptoms and diagnosis of ASDs and three excerpts of testimony
from the OAP. See Respondent’s Exhibits [“Res. Exs.”] A-E.

       Although petitioners did not precisely object to respondent’s evidence, they
described it as filed after “the deadline to submit evidence.” Pet. Reply at 1.



depicted. I will refer to these notes as the video narrative. However, the video narrative sometimes
describes events not depicted on the video and, on occasion, inaccurately describes what appears on the
video clips. Where there are conflicts, I rely primarily on the video clips, rather than the narrative.
15
   G.R. Delong, et al, Acquired Reversible Autistic Syndrome in Acute Encephalopathic Illness in
Children, 38(3) ARCH NEUROL 191-94 (1981). This article, which is more than three decades old, reports
on three cases of late onset of autistic symptoms (at 5, 7 ½, and 11 years of age) in conjunction with “an
acute encephalopathic illness.” Id. at 193. None of the illnesses were attributed to a vaccination. One of
the children was diagnosed with encephalitis caused by a herpes virus infection. Id. at 192. Whether an
acute encephalopathy caused by illness can present with symptoms similar to autism does not appear to
be in issue; rather, the issue in this case is whether W.J.B. had symptoms consistent with an acute
encephalopathy following the allegedly causal vaccinations. Thus, I did not find this article relevant to the
issues in dispute.
16
  During the status conference, the special master once again reviewed the definition of a Table
encephalopathy as set forth in the QAI section of the Vaccine Injury Table. When petitioners’ counsel
argued that the definition found in the QAI would not be acceptable to the medical community at large, the
special master observed that the narrower definition in the Table was intentionally more restrictive. Id.;
see also infra discussion at Section II.D.2. She noted that petitioners’ counsel seemed to be arguing for a
change to the QAI definition, a request that she could not grant. Order, issued Jan. 23, 2013, at 2.

     See supra, note 3.

                                                      5
Petitioners’ description is incorrect. The special master formerly assigned to the case
imposed a deadline in October 2012 for documents upon which the parties intended to
rely during the November 2012 fact hearing. See Order, issued Sept. 13, 2012, at 2.
This deadline did not preclude the parties from filing evidence after the fact hearing that
related to issues raised during the hearing or in subsequent filings. Moreover,
petitioners indirectly raised an actual causation claim in their April 4, 2013 motion and
supporting documents and did so more explicitly in their reply to respondent’s filings.
See Pet. Reply at 3-4. Under these circumstances, it was appropriate for respondent to
file additional evidence as a part of the ruling on the record process.

        However, sua sponte, I have elected to disregard Res. Ex. D, the excerpt of the
OAP testimony of Dr. Max Wiznitzer. Doctor Wiznitzer was one of W.J.B.’s treating
physicians at a time prior to presenting his OAP testimony. See Pet. Ex. 6, pp. 1-4.
(records reflecting Dr. Wiznitzer’s treatment). Although it does not appear that W.J.B. is
still one of Dr. Wiznitzer’s patients and Dr. Wiznitzer’s OAP testimony did not involve
W.J.B.’s care and treatment, to avoid any potential or actual conflict of interest for Dr.
Wiznitzer, I will not consider his OAP testimony.

       This case is now ready for a decision. In Section II, I set forth the evidence
regarding W.J.B.’s health and development prior to his MMR vaccination and the
symptoms he manifested in the relevant period after the vaccination, the requirements
to establish a Table injury, and my conclusions regarding the Table injury claim. In
Section III, I discuss the evidence for actual causation.

       Having considered the record as a whole, I find that petitioners have failed to
establish the factual predicate for a Table injury. I hold that they have failed to
demonstrate by preponderant evidence that the MMR vaccination actually caused
W.J.B.’s autism spectrum disorder.

                                      II. The Table Injury Claim.

A. Summary.

        The evidence regarding W.J.B.’s condition prior to and following the MMR
vaccination on January 4, 2000 is conflicting, but the fact that W.J.B. exhibited some
symptoms consistent with an ASD after his MMR vaccination is not disputed.
Petitioners described the symptoms as “encephalopathic changes,” arguing that W.J.B.
suffered a Table encephalopathy.18 Pet. Motion at 1; see also Pet. Reply at 1-3
(petitioners contrasting autism and encephalopathy). Asserting that petitioners’ claim of


18
  As addressed in more detail below, petitioners persistently conflate the terms “encephalopathy” and
“encephalopathic” with the term “encephalopathy” as defined in the Vaccine Injury Table. Within the
context of a Table injury claim, “encephalopathy” is a term of art, with a very specific definition. In logic’s
terminology, all Table encephalopathies are encephalopathies, but only some encephalopathies meet the
exacting Table definition.

                                                       6
a Table encephalopathy is unsupported by the evidence, respondent described W.J.B.’s
symptoms as “subtle and consistent with the emergence of an autism spectrum
disorder.” Respondent’s Response to Pet. Motion [“Res. Response”] at 7.

       Respondent’s assertions are supported by the evidentiary record; for the most
part, petitioners’ assertions are not. In contrast to the often subtle onset of behaviors
associated with ASDs, there is little that is subtle about an acute encephalopathy that
meets the Table definition of this condition. It is a condition that is so serious as to
require hospitalization, whether or not hospitalization actually occurred. 42 C.F.R. §
100.3(b)(2)(i).

       Even accepting petitioners’ hearing testimony and affidavits as true and correct
regarding W.J.B.’s condition at the relevant time periods (between January 9-19, 2000
for onset of an acute Table encephalopathy and for the six months thereafter for a
chronic Table encephalopathy), their evidence falls far short of that necessary to
establish that W.J.B. sustained either an acute or chronic Table encephalopathy. Other
evidence of record, including petitioners’ own journal, video records, and medical
records, make plain that W.J.B. never met the requirements for an acute Table
encephalopathy.

B. Requirements for a Table Encephalopathy.

      To establish an MMR-Table encephalopathy, petitioners must demonstrate
W.J.B. suffered an “encephalopathy” as defined by the QAI section to the Vaccine Injury
Table within five to fifteen days of his MMR vaccination. 42 C.F.R. § 100.3(a). Since
W.J.B. received the MMR vaccine on January 4, 2000, petitioners must establish the
onset of a Table encephalopathy during the period from January 9 to 19, 2000.

       1. The Table Definitions.

      According to the QAI, a vaccinee is considered to have suffered a Table
encephalopathy if the vaccinee manifests an injury encompassed in the definition of an
acute encephalopathy within the appropriate time period, and if a chronic
encephalopathy is present for more than six months after the immunization. 42 C.F.R.
§ 100.3(b)(2).

       An acute encephalopathy is “one that is sufficiently severe so as to require
hospitalization (whether or not hospitalization occurred).” 42 C.F.R. § 100.3(b)(2)(i).
For a child younger than 18 months of age,19 presenting without an associated seizure
event, an acute encephalopathy is indicated “by a significantly decreased level of
consciousness . . . lasting for at least 24 hours.” 42 C.F.R. § 100.3(b)(2)(i)(A). A


19
  W.J.B. was not 18 months old until January 24, 2000, placing his case in the “younger than 18 months”
period for purposes of evaluating whether he experienced an acute encephalopathy.

                                                   7
significantly decreased level of consciousness is indicated by the presence of one of
three clinical signs for a period of at least 24 hours: “(1) Decreased or absent response
to environment (responds, if at all, only to loud voice or painful stimuli); (2) Decreased or
absent eye contact (does not fix gaze upon family members or other individuals); or (3)
Inconsistent or absent responses to external stimuli (does not recognize familiar people
or things).” 42 C.F.R. § 100.3(b)(2)(i)(D). Sleepiness, irritability (fussiness), high-
pitched and unusual screaming, persistent inconsolable crying, and bulging fontanelle
are not, alone, or in combination, a demonstration of an acute encephalopathy. 42
C.F.R. § 100.3(b)(2)(E).

       A chronic encephalopathy is defined in the QAI as “a change in mental or
neurologic status, first manifested during the applicable time period, [that] persists for a
period of at least 6 months from the date of vaccination.” 42 C.F.R. § 100.3(b)(2)(ii). If
a person returns to a typical neurologic state after suffering an acute encephalopathy,
he or she is not presumed to have suffered residual neurologic damage and “any
subsequent chronic encephalopathy shall not be presumed to be a sequela of the acute
encephalopathy.” Id.

       2. Analysis of the Table Requirements.

       “The symptoms associated with an acute encephalopathy are neither subtle nor
insidious.” Waddell v. Sec’y, HHS, 2012 WL 4829291, at *6 (Fed. Cl. Spec. Mstr. Sept.
19, 2012). As noted in Waddell, “[t]he hospitalization requirement underscores how
serious the symptom presentation must be after vaccination to merit classification as a
Table encephalopathy.” 2012 WL 4829291, at *7 (citing to Revision of the Vaccine
Injury Table, 60 Fed. Reg. 7,685, 7,687 (Feb. 20, 1997) (preamble to final rule) (“[W]e
did not intend that hospitalization be viewed as an absolute requirement to establish an
acute encephalopathy, but rather as an indicator of the severity of the acute event.”).

       The descriptions of the clinical signs added to the QAI also illustrate the severity
of the symptoms required to demonstrate acute encephalopathy. See 42 C.F.R. §
100.3(b)(2)(i)(D). In amending the QAI, the Secretary of Health and Human Services20
included the specific clinical signs at 42 C.F.R. § 100.3(b)(2)(i)(D) in an effort to “clearly
distinguish infants and children with brain dysfunction from those with transient
‘lethargy,’” noting that the severity and duration of “more serious impairment of
consciousness that is the hallmark of encephalopathy” differentiated it from the
“diminished alertness and motor activity” of lethargy following a fever or illness. 60 Fed.
Reg. 7678, 7687 (Feb. 8, 1995). The “‘significantly decreased level of consciousness’
[required in the QAI definition] refers to a state of diminished alertness that is much
more than mere sleepiness or inattentiveness.” Waddell, 2012 WL 4829291, at *7.

  See Revision of the Vaccine injury Table, 60 Fed. Reg. 7678, 7679-80 (Feb. 8, 1995) (discussing the
Secretary’s authority to modify both the Vaccine Table and QAI section).

                                                   8
        In contrast, encephalopathy21 as commonly used in the medical community
encompasses a much broader class of injuries than the more stringent definition of
acute encephalopathy found in the QAI. As explained in Waddell, “[t]he scope of the
medical term ‘encephalopathy’ is more expansive than the narrower, statutory definition
set forth in the Table.” 2012 WL 4829291, at *12 (referencing Hazelhurst, 2009 WL
332306, at *26-29). The QAI definition of acute encephalopathy simply does not
encompass every type of brain dysfunction to which the broader meaning of
“encephalopathy” applies.

C. Evidence Regarding W.J.B.’s Condition During the Relevant Time Frames.

        1. Facts Not Reasonably Subject to Dispute.

       W.J.B.’s birth on July 24, 1998 and early childhood were essentially normal. He
received the usual childhood vaccinations at two, four, six, nine, 12, and 17 months of
age without apparent ill effects. Pet. Ex. 1, pp. 4-9. He suffered from several childhood
illnesses, including an upper respiratory infection (URI) at about three weeks of age,
and similar illnesses on several other occasions after six months of age. He also had a
number of ear infections. See Pet. Exs. 1, pp. 2, 11-15; 12, p. 1. At 16 months of age,
he was diagnosed with allergic rhinitis. Pet. Ex. 1, p. 14.

       On two occasions in early childhood, W.J.B. failed to meet a developmental
milestone. Pet. Ex. 1, p. 7 (did not pull to stand at nine months of age); p. 8 (did not use
a cup at twelve months of age). Otherwise, he appeared to be developing normally
through about 17 months of age. See generally, id., pp. 1-15. He met all
developmental milestones at a well child visit on December 19, 1999, at about 17
months of age, including speaking three to six words. His behavior was assessed as
normal, but he reportedly suffered from night terrors. Id., p. 9. He received several
vaccinations at this visit, but his initial MMR vaccination was postponed until after the
holidays. Id., pp. 1, 9.

       Just prior to the administration of W.J.B.’s MMR vaccination, both of his parents
had a flu-like illness with vomiting and diarrhea. It is not entirely clear from the records
and testimony whether W.J.B. was ill, too, or merely tired and irritable.22 However, after
examining W.J.B. on January 4, 2000, his pediatrician noted he was alert and playful,
and concluded that he could receive the MMR vaccine. Pet. Ex. 1, p. 15.

       2. The Evidence Regarding W.J.B.’s Condition after the MMR Vaccination.

       The evidentiary record regarding W.J.B.’s condition after the allegedly causal
vaccination is conflicting. Assuming, arguendo, that petitioners’ testimony and affidavit
correctly reflect the symptoms W.J.B. displayed and timing of these symptoms, their
evidence, as the previous special master noted after the hearing, fails to establish that
W.J.B. sustained an acute Table encephalopathy during the relevant period.

               a. Petitioners’ Testimony and Affidavits.

        Petitioners testified that the first symptom of W.J.B.’s encephalopathy, two
shuddering episodes, occurred at a family dinner on January 9, 2000. This date is the
first date of the five to fifteen day time period during which a Table injury must manifest

        Petitioners claim that by the end of time period (January 19, 2000), W.J.B.
exhibited numerous symptoms of a Table encephalopathy. In their amended petition,
petitioners asserted “[o]ver the next several weeks, and by January 19, 2000, [W.J.B.]
had difficulties responding to his name, decreased eye contact, perseverative behavior,
decreased speech, increased crying, decreased smiling and laughing, sleep problems,
selective eating, asocial behavior, and did not look happy” (Am. Petition, ¶ i). With
some variations and a few omissions, petitioners repeated these claims in their affidavit,
adding that W.J.B. also “had a marked decrease in coordination, increased sensitivity to
sounds,” and was less responsive to his parents and objects or people in his
environment. Affidavit, ¶ h.

       Although petitioners described similar symptoms during their testimony, they
often indicated they did not notice a particular symptom until days or even weeks after
January 19, 2000. For example, Mrs. Blake testified that she did not notice many of
W.J.B.’s symptoms until she experienced a “very clear manifestation” on January 31,
2000, that W.J.B.’s communication, motor control, and social relationships were
different.23 Tr. at 63.

       Petitioners testified that over the remainder of January 2000 and beyond, W.J.B.
became less social (Tr. at 61-63, 81-82, 163), less responsive to them and others (Tr. at
56, 60), had decreased eye contact (Tr. at 56), lost language skills (Tr. at 56, 63, 68,
141-42), began head-banging (Tr. at 64-68, 138-40), experienced a deterioration in
motor skills (Tr. at 63, 137-38), exhibited perseverative behaviors (Tr. at 56-57, 60, 68,
81-82, 138), had difficulty sleeping (Tr. at 87, 159), was more irritable, screamed and
cried (Tr. at 56, 87, 155), and became a picky eater (Tr. at 58, 140-41).


23
  Mrs. Blake testified that on January 31, 2000 she was struck by the similarities between W.J.B.’s
behavior and the actions of three of the residents at the adult group home where she was working as an
occupational therapist. Tr. at 62-63.

                                                  10
                   b. Other Evidence.

       If petitioners’ own testimony does not make their Table injury claim untenable,
other evidence certainly does. The medical records, videos of W.J.B. during the period
when the Table encephalopathy allegedly occurred, and petitioners’ own journal
conclusively demonstrate that there was no Table encephalopathy. Rather, W.J.B.
continued to manifest symptoms of an ASD, including the intensifying of some
symptoms displayed prior to the MMR vaccination.

                           (1) Medical Records.

        W.J.B. did not visit his pediatrician for nearly four weeks after his MMR
vaccination on January 4, 2000. Thus, there were no medical records created during
the five-to fifteen-day period after vaccination. There were, however, medical records
documenting other illnesses within two to three months of the MMR vaccination which
are remarkable in their lack of any mention of symptoms consistent with an acute Table
encephalopathy in mid-January 2000.

        On January 31, 2000, Mrs. Blake called the pediatrician’s triage center because
W.J.B. had experienced two days of a low-grade fever and had a loose cough, a runny
nose, and reduced oral intake. Pet. Ex. 1, p. 20. She was advised to call back if his
fever lasted for more than three days, if there was thick, yellow nasal discharge for
longer than 48 hours, if there was clear nasal discharge lasting more than 10 days, or if
W.J.B. became worse. Id.

       The next day, on February 1, 2000, W.J.B.’s symptoms continued and he was
seen by his pediatrician. Pet. Ex. 1, p. 15. At the visit he was observed to be alert and
playful, but was diagnosed with another ear infection. Id.

       Two days later, on February 3, 2000, W.J.B.’s mother called the triage center
because W.J.B. had been “ill all week.” Pet. Ex. 1, p. 21. He was afebrile, but was
moaning and crying. Petitioners requested to speak to a doctor as Mr. Blake felt W.J.B.
was getting worse and were advised to take W.J.B. to the emergency room. They
returned home from the emergency room without being seen because there was a two
hour wait. At home, Mr. Blake placed another call to the triage center, spoke to a
physician, and indicated that he and Mrs. Blake felt W.J.B. could be seen again in the
morning.24 Pet. Ex. 1, p. 21.

        On February 4, W.J.B.’s pediatrician examined him and diagnosed him with
sinusitis. Pet. Ex. 1, p. 15. He also documented a concern about W.J.B.’s speech. The
entry indicated that the pediatrician intended to discuss speech concerns at a follow up


24
     During hearing, Mrs. Blake testified that she did not remember this incident clearly. Tr. at 74.

                                                        11
visit. Id., p. 15. In early March 2000, the pediatrician referred W.J.B. to the Cleveland
Clinic for Hearing and Speech. Id., p. 16.

       On February 24, 2000, Mrs. Blake called the triage center because W.J.B. had
vomited. Pet. Ex. 1, p. 22. She indicated that W.J.B. did not have a seizure, had eaten
well that day, and was afebrile and voiding but that he “does hit his head” on the wall or
floor during temper tantrums. Id. This was the first mention of “head-banging” in
W.J.B.’s medical records, although a journal entry from January 24 mentions a head-
banging incident.25 Mrs. Blake relayed that W.J.B. “ha[d] a bruise on his forehead” but
was “playful.” Pet. Ex. 1, p. 22. The vomiting was assessed as viral gastritis and Mrs.
Blake was instructed to apply ice to W.J.B.’s head, call back if pain persisted for more
than 20 minutes, and to follow-up with his primary care physician.

        Approximately an hour later, Mr. Blake called back, indicating he had called 911
after W.J.B. vomited again. Although the emergency medical service (EMS) provider
was present and believed W.J.B. to be fine, Mr. Blake requested to speak to a doctor.
W.J.B. was seen by his pediatrician the next day and diagnosed with another ear
infection.26 Pet. Ex. 1, p. 16. During that visit, his parents reported that he had been
head banging for two weeks. Id. This would place onset of W.J.B.’s head banging at
around February 10, 2000, although the journal entry for January 24, 2000 reflected an
earlier incident. Pet. Ex. 16 at 3.

       In mid-March, Mrs. Blake reported more troubling behavior by W.J.B. She
described him as being inactive, staring at lights, pulling at his sleeves, and hiding in the
closet. Pet. Ex. 1, p. 26. On April 8, 2000, W.J.B.’s parents brought him to the
pediatrician because he was exhibiting behaviors consistent with PDD and obsessive
compulsive disorder [“OCD”]27 and had been less responsive to them during the past
week. They also described a decrease in language. Pet. Ex. 1, p. 16. They indicated
the “PDD like behavior started since January after [the] MMR [vaccination].” Id. W.J.B.
was referred for a behavioral health evaluation. Id. He underwent an occupational
therapy evaluation on April 22, 2000 and began receiving occupational therapy. Pet.
Ex. 3, p. 1.




25
   Pet. Ex. 16 at 13. According to the journal entry, W.J.B. banged his head when Mrs. Blake would not
allow him to play with electrical cords.
26
  The antibiotics prescribed for W.J.B.’s ear infection caused him to develop diarrhea. See Pet. Ex. 1, p.
25. After a few days, W.J.B.’s parents took him back to the pediatrician, who diagnosed enteritis. Pet.
Ex. 1, p. 16. Enteritis is an intestinal inflammation characterized by vomiting and lethargy. DORLAND’S at
624.
27
   OCD is an anxiety disorder characterized by recurrent obsessions or compulsions that are severe
enough to interfere significantly with personal or social functioning. Performing compulsive rituals may
release tension temporarily, and resisting them causes increased tension. DORLAND’S at 551.

                                                    12
                b. Video Records 28 and Petitioners’ Journal.

        The video evidence stands in sharp contrast to petitioners’ claims. There are no
significant differences in W.J.B.’s behavior before and after his MMR vaccination
depicted on the videos from November 1999 to January 2000. Likewise, petitioners’
journal entries reflect a child who was engaged with his parents and his environment
throughout January 2000.

        Journal entries from January 2000, and, in particular, those from January 9-19,
unequivocally contradict petitioners’ claims. Rather than describing a child with a
significantly decreased level of consciousness, these entries contain multiple references
to W.J.B. dancing, singing, laughing, asking for things, learning new colors or words,
and noticing when his blue block was missing. Pet. Ex. 16 at 10-12. There are also
entries reflecting W.J.B.’s responses to his environment. He cried when another child
took his blue block (on January 6), when his mother “flew” another child (on January 7),
when left with a babysitter (on January 8, 15, and 23), when his mother tried to give him
a noodle from her soup (on January 10), when his father went to work (on January 12
and 26), and when the doorbell rang (on January 15). Id. at 10-13.

        W.J.B. did not talk much on any of the video clips. However, petitioners’ journal
contradicts Mrs. Blake’s testimony regarding W.J.B.’s use of words during the period
after his MMR vaccination. From January 9-19, there are entries indicating that W.J.B.
was speaking and no indication that he was experiencing a loss of language skills. The
journal records W.J.B. asking for more “milk” on January 12 (Pet. Ex. 16 at 11) and
learning the words “more” and “up” on January 18 (id. at 12).

        In video clips recorded before and after vaccination, W.J.B. ignored his parents’
attempts to get his attention. Pet. Ex. 18A at 14:28-16:10, 22:10-23:47, 24:02-25:41.
Contrary to assertions that he was unresponsive to his parents, the January 15 video
clip reflects that W.J.B. was excited and responded to his father when Mr. Blake
mentioned the “Irish Trot.” Pet. Ex. 18A at 27:17-29.

        The journal contains several notations of behaviors that might be indicative of an
emerging ASD diagnosis. However, none of the journal entries in January 2000 reflect
a child who had ceased interacting with his parents or environment. He was described
as tired on January 11, and “not too excited” and “pretty quiet” on the evening of
January 19 at Gymboree. Pet. Ex. 16 at 11-12. However, on both days, W.J.B. also
was described as singing, slow dancing, playing independently with toys, and pointing
to the refrigerator for his “bedtime bottle” (on January 11) and waving “Bye-Bye to
Daddy” in the morning, having the giggles with mommy when she blew on his feet, liking


28
  Although the record contains photographs as well as video evidence, the photographs do not provide
evidence about W.J.B.’s language abilities, motor skills, or social skills. Although I have examined them,
they are not otherwise discussed in this decision.

the stuffed blue bear, exploring doors and cupboards, enjoying the bubble lights,
crawling in the ball pit, and becoming jealous of his mother’s friend’s baby (on January
19). Id.

E. Evaluating Petitioners’ Table Encephalopathy Claim.

        Conflicts between contemporaneous medical records and subsequent
statements are common in Vaccine Act cases, with special masters frequently
according more weight to the symptoms contemporaneously recorded, rather than
those recounted in later medical histories, affidavits, or trial testimony. “It has generally
been held that oral testimony which is in conflict with contemporaneous documents is
entitled to little evidentiary weight.” Murphy v. Sec’y, HHS, 23 Cl. Ct. 726, 733 (1991);
see also Cucuras v. Sec’y, HHS, 993 F.2d 1525, 1528 (Fed. Cir. 1993). Memories are
generally better the closer in time to the occurrence reported and when the motivation
for accurate explication of symptoms is more immediate. Reusser v. Sec’y, HHS, 28
Fed. Cl. 516, 523 (1993). Inconsistencies between testimony and contemporaneous
records may be overcome by “clear, cogent, and consistent testimony” explaining the
discrepancies. Stevens v. Sec’y, HHS, No. 90-221V, 1990 WL 608693, at *3 (Fed. Cl.
Spec. Mstr. Dec. 21 1990).

        Petitioners argue that W.J.B.’s shuddering episodes and behavioral symptoms
began between January 9-19, 2000, and by January 19 constituted at least one of the
clinical signs of the significantly decreased level of consciousness required by the QAI
definition of an acute encephalopathy. Pet. Motion at 1. Even if I accepted their
testimony as accurately depicting W.J.B.’s condition and behavior during the January
2000, these symptoms are insufficient to meet the acute Table encephalopathy
requirements, although they may well be indicative of the emergence of his ASD. I
make the following factual findings and conclusions of law regarding the Table injury
claim.

        1. Factual Findings.

               a. W.J.B. experienced two “shuddering” episodes at a family dinner on
January 9, 2000, but his parents did not consider them serious, as they did not seek any
medical attention at all for W.J.B. until 22 days later, and did not mention the episodes
to his physician at this medical visit, the one closest in time to their occurrence.

              b. There is no evidence that these shuddering episodes were seizure-
related. His physician called them “baby stress” when they were first described to a
medical professional months later.29 Ms. Patricia Blake, a nurse-practitioner and

29
   The shuddering episodes were not mentioned in the medical records for seven months after their
occurrence. The first report appears in occupational therapy notes from Sensory Connections on August
10, 2000. Pet. Ex. 13, p. 1. Information from Dr. Derrick Lonsdale regarding this shuddering episode was
added to the records of W.J.B.’s initial pediatrician (Dr. Wamsley) on February 16, 2001. See Pet. Ex. 1,
p. 18. Records from 2001 visits to Dr. Bauer, a developmental pediatrician, and Dr. Wiznitzer, a pediatric
                                                       14
W.J.B.’s aunt, who had phone conversations with Mrs. Blake in February 2000 about
W.J.B.’s behavior, did not mention the shuddering episodes in her affidavit, suggesting
that they were not matters of concern.

            c. According to the medical records filed in this case, W.J.B. has never
been diagnosed as having seizures or a seizure disorder.

              d. Concerns about W.J.B.’s speech were first raised at a medical visit on
February 4, 2000. Based on the physician’s indication that he would discuss them with
Mrs. Blake at the next scheduled pediatric visit, as opposed to the sick child visit at
which they were presented (see Pet. Ex. 1, p. 15), I conclude that the speech concerns
were not acute, such as a complete loss of language or cessation of communication
during the relevant period. This conclusion is buttressed by petitioners’ journal, which
records asking for more “milk” on January 12 (Pet. Ex. 16 at 11) and learning the words
“more” and “up” on January 18 (id. at 12).

              e. Despite the fact that petitioners had previously sought medical
treatment for ear infections, stuffiness, teething, coughing at night, and URIs, they did
not contact a medical professional about W.J.B.’s condition until 27 days after
vaccination. At this visit, they did not describe any symptoms consistent with an acute
encephalopathy during the period between this visit and the MMR vaccination.

               f. The concerns expressed by petitioners in telephone consultations and
doctor visits on January 31 and in early February 2000 involved W.J.B.’s recent
symptoms of low grade fever, loose cough, runny nose, and lack of appetite (see Pet.
Ex. 1, pp. 20-21) and diagnoses of an ear infection and sinusitis (see id., p. 15), not an
encephalopathic condition involving loss of responsiveness to his family or environment.

               g. W.J.B.’s physician examined him at his February 2000 office visits.
W.J.B. was described as alert and playful at the February 1, 2000 office visit. The
results of those examinations and descriptions of W.J.B.’s demeanor are inconsistent
with the presence of either an acute or chronic encephalopathy, as defined in the QAI.

            h. While some symptoms of an ASD either occurred or intensified during
January 2000, these symptoms were not of the nature or severity so as to constitute a
Table encephalopathy.

               i. Video clips taken during the five to fifteen days after the MMR
vaccination and, more specifically, the video from January 19, 2000, does not show a
child suffering from a Table encephalopathy. Rather, W.J.B. is moving with greater
independence during the Gymboree session on January 19, 2000 than during a



neurologist, also mention this incident. See Pet. Exs. 12, p. 1 (February 27, 2001 visit to Dr. Bauer); 6, p.
1 (July 18, 2001 visit to Dr. Wiznitzer).

                                                     15
previous session on November 17, 1999. Compare Pet. Ex. 18A at 30:01-32:35 with id.
at 3:07-6:38. W.J.B.’s activity level, appearance, and interactions conclusively
demonstrate that he was not suffering from an acute encephalopathy during the
January 19, 2000 session.

              j. Journal entries from the five to fifteen days after the MMR vaccination
provide no evidence that W.J.B. was suffering from a Table encephalopathy. Instead,
the entries depict a child who is alert, interactive, responsive, and learning.

       2. Conclusions of Law.

        The special master formally assigned to the case repeatedly warned counsel that
W.J.B.’s symptoms were not sufficient to establish a Table encephalopathy but more
closely resembled symptoms of autism. See Order, issued Oct. 5, 2011, at 1; Order,
issued Feb. 15, 2012, at 6; Order, issued Jan. 23, 2013, at 2. After a thorough review of
the record, I concur with her conclusions. Given the description of the clinical signs
listed in the QAI and the requirement that the symptoms be severe enough to require
hospitalization, even if I accepted petitioners’ allegations as true, they are insufficient to
establish the factual predicate for an acute encephalopathy. Other than descriptions of
the shuddering episodes on January 9 and behavior during the Gymboree session on
January 19, petitioners have not provided specific instances of symptoms or behavior
which occurred during the time period in question.

        Their failure to seek any medical attention for W.J.B. during the five to fifteen day
period after his MMR vaccination, coupled with their previous visits for mild illnesses,
undercuts their claim that he had an injury consistent with a Table encephalopathy
during this period. According to their testimony, petitioners did not understand the
significance of much of the behavior upon which they rely until later and, thus, they
attempt to explain why they did not seek medical attention for W.J.B. during January
2000. However, an acute encephalopathy is a striking and concerning event, and
unlikely to be unnoticed at the time it begins.

        There is no reliable evidence that W.J.B. experienced an acute encephalopathy,
as defined by the Vaccine Injury Table and the QAI, within five to fifteen days of his
MMR vaccination. Furthermore, the video, medical, and journal records establish that
although W.J.B. may have displayed symptoms of an autistic disorder both before and
after his MMR vaccination, he did not manifest a chronic encephalopathy, as defined by
the Table, during the six month period following this vaccination.

       I hold that W.J.B.’s condition after receipt of the MMR vaccination does not meet
the requirements established by the Vaccine Injury Table for a Table encephalopathy.




                                             16
                   III. Onset of ASD Symptoms and Actual Causation.

       W.J.B. was diagnosed with highly functioning ASD (Asperger’s) on July 11, 2000.
Pet. Ex. 5, pp. 1, 3. Such a diagnosis necessarily involves behavioral symptoms which
may include changes from earlier behaviors.30 Most children later diagnosed with
autism spectrum disorders cannot be reliably distinguished from typically developing
children before 12 months of age because the behaviors that are associated with autism
do not emerge in most cases until the second or third years of life.

        Although some autistic behaviors can occur suddenly, they most often manifest
over time, and their significance may not be apparent when they first begin. These
behaviors may include the loss of skills once demonstrated (a regression), the failure to
acquire skills at all or at an age-appropriate time, or the manifestation of stereotypic or
abnormal behaviors (such as hand flapping, perseverative behaviors, or a fascination
with light switches, ceiling fans, or parts of an object), among many others.

        Given W.J.B.’s ASD diagnosis, the fact that W.J.B.’s behavior changed over time
is not remarkable or disputed. When specific behaviors began or intensified is
significant. For petitioners’ actual causation claim, manifestation prior to the allegedly
causal vaccination undercuts their claim that the MMR vaccine caused W.J.B.’s
condition. And, if petitioners’ recollections regarding what happened and when it
happened are in conflict with contemporaneously recorded evidence (such as medical
records, videos, and journals), I must decide what evidence to credit. To the extent an
expert or treating physician relies on evidence that I reject, the opinions of those
physicians may become less reliable.

A. Timing of W.J.B.’s Autistic Symptoms.

      A thorough review of the evidence shows that W.J.B. exhibited some autistic
behavior prior to vaccination. Over time, these behaviors became more intense and
apparent while additional behaviors became evident.

       Prior to vaccination, Mr. Blake described W.J.B. as being an affectionate and
completely normal child with appropriate social interactions and good eye contact. Tr.
at 125-26, 133. Mrs. Blake recalled W.J.B. being very interactive, having many play
dates and being very involved socially with his family, aware of his surroundings, and
aware of the family dog. Tr. at 55-56. Both pointed to a picture of W.J.B. sitting on a
car toy with another child as evidence of his normal play and interaction with other
children. Tr. at 34-35, 133.

   See White v. Sec’y, HHS, No. 04-337V, 2011 WL 6176064, at *4-9 (Fed. Cl. Spec. Mstr. Nov. 22, 2011)
(discussing of the symptoms of and diagnostic criteria for autism under the DSM-IV-TR). The DSM-IV-TR
has since been replaced by the DSM-V but the discussion of the symptoms of autism found in White is
still relevant.

       Despite petitioners’ assertions, it is clear that, prior to vaccination, W.J.B. was not
as interactive and socially involved as petitioners maintain. Because it is difficult to
measure social interaction, responsiveness, and eye contact in a still photograph, the
pictures highlighted by petitioners provide little support for their claims. The video,
however, contains multiple instances prior to vaccination when W.J.B. was playing
alone and failed to respond to his parents or others. See Pet. Ex. 18A at 13:52-25:43.

        For example, on December 24, 1999,31 W.J.B. ignored several of his father’s
attempts to engage with him. Pet. Ex. 18A at 14:28-16:10. When playing patty-cake
with his grandmother, W.J.B. stared at the fireplace through almost the entire segment.
Id. at 16:14-18:00. Petitioners’ video narrative describes this behavior, indicating W.J.B.
“seem[ed] to be watching the fire in the fireplace [and didn’t] really look at Grandma
directly.” Pet. Ex. 17 at 4 (emphasis in original). On January 5, 2000, he ignored his
father completely, preferring instead to play with the stereo system. Pet. Ex. 18A at
22:10-23:47. That same day, he ignored both parents when playing with magnets on
the refrigerator, responding only once when Mrs. Blake asked him what a cow says.
During the rest of the video segment, W.J.B. ignored multiple attempts by his parents to
get his attention. Id. at 24:02-25:41.

        With regard to speech delay, W.J.B. was not speaking much prior to vaccination.
As evidenced on the video submitted, W.J.B.’s speech ability is fairly consistent; at all
times, he spoke little, saying a word or making a sound rarely, if ever. Watching the
video from November 17, 1999 (prior to vaccination), I do not hear the verbalization
petitioners described in their notes, nor do I see the “rich non-verbal communication”
they reference. Compare Pet. Ex. 18A at 3:50-6:45 with Pet. Ex. 17 at 2.

       From the evidence submitted, W.J.B. showed a decreased level of eye contact,
responsiveness, speech and social interaction prior to receiving the MMR vaccine.
Clearly, these autistic symptoms were not caused by the MMR vaccine.32 Even so, I will
discuss the evidence needed to prove vaccine causation and determine if petitioners
have met their burden in this case.

B. Legal Requirements for Demonstrating Vaccine Causation.

       The Federal Circuit has set forth three factors petitioners must establish to prove
causation in off-Table cases. See Althen, 418 F.3d 1274, 1278 (Fed. Cir. 2005). Althen
requires petitioners to provide: “(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



31
     The date is derived from Mr. Blake’s remark on the video that it was Christmas Eve.
32
  Petitioners have not asserted a significant aggravation claim, nor is there any evidence in the record
before me that such a claim would be tenable.

                                                      18
between vaccination and injury.” Id. All three prongs of the Althen test must be
satisfied by preponderant evidence. de Bazan v. Sec’y, HHS, 539 F.3d 1347, 1351-52
(Fed. Cir. 2008); Caves v. Sec'y, HHS, 100 Fed. Cl. 119, 132 (2011), aff’d per curiam,
463 Fed. Appx. 932, 2012 WL 858402 (Fed. Cir. 2012) (finding that “[w]hen a petitioner
seeks to demonstrate causation in fact by meeting the three Althen requirements, each
of those requirements must be proven by a preponderance of the evidence”).

       Petitioners may satisfy this evidentiary burden by relying either on “medical
records or medical opinion.” Althen, 418 F.3d at 1279 (emphasis in original). Causation
is determined on a case by case basis, with “no hard and fast per se scientific or
medical rules.” Knudsen v. Sec’y, HHS, 35 F.3d 543, 548 (Fed. Cir. 1994). Close calls
regarding causation must be resolved in favor of the petitioner. Althen, 418 F.3d at
1280. But see Knudsen, 35 F.3d at 550 (when evidence is in equipoise, the party with
the burden of proof fails to meet that burden).

        1. Lack of a Reliable Medical Theory.

       To satisfy the first prong of the Althen test, petitioners must provide “a medical
theory causally connecting the vaccination and the injury.” Althen, 418 F.3d at 1278
(quoting Grant v. Sec’y, HHS, 956 F.2d 1144, 1148 (Fed. Cir. 1992)). The medical
theory must be a reliable one. Knudsen, 35 F.3d at 548 (“This ‘logical sequence of
cause and effect’ must be supported by a sound and reliable medical or scientific
explanation.”). Petitioners must prove the existence of this medical theory by a
preponderance of the evidence. Broekelschen v. Sec’y, HHS, 618 F.3d 1339, 1350
(Fed. Cir. 2010). In other words, petitioners must show that it is more likely than not
that the received vaccine can cause the alleged injury. Pafford, 451 F.3d 1352, 1355-
56 (Fed. Cir. 2006) (emphasis added).

        In this case, petitioners have failed to proffer any theory explaining how the MMR
vaccination can cause an encephalopathy manifesting as autism. Instead, they simply
claim that “[t]he Table itself provides the medical theory that the MMR [vaccine] can
cause an encephalopathy.” Pet. Reply at 4. Petitioners are conflating Table and non-
Table injuries. Having failed to establish a Table injury claim, petitioners cannot rely on
the Table.33 Rather, petitioners must satisfy the first test in proving causation by setting
forth a reliable medical theory.34 They have failed to do so.

33
  “Simple similarity to conditions or time periods listed in the Table is not sufficient evidence of causation;
evidence in the form of scientific studies or expert medical testimony is necessary to demonstrate
causation for such a petitioner.” Grant v. Sec’y, HHS, 956 F.2d at 1148 (quoting H.R.REP. NO. 99–908,
99th Cong., 2d Sess., pt. 1, at 15 (1986), reprinted in 1988 U.S.C.C.A.N. 6344, 6356).
34
  An impressive body of medical and scientific evidence regarding the claim that the MMR vaccine could
cause ASDs was adduced in the OAP Theory 1 test cases, with the three special masters who heard this
evidence concluding that the issue of MMR causation was not a “close call.” Cedillo, 2009 WL 331968, at
*135; Hazlehurst, 2009 WL 332306, at *172; Snyder, 2009 WL 332044, at *198. Each special master
independently determined that the medical theories advanced were not reliable and that the test case
petitioners had failed to produce preponderant evidence that the MMR vaccine could cause ASDs.
                                                    19
        2. Lack of a Logical Sequence of Cause and Effect.

       Even if petitioners had provided a theory which satisfied the first prong, to satisfy
the second prong of the Althen test, petitioners must establish a “logical sequence of
cause and effect showing that the vaccination was the reason for the injury.” Althen,
418 F.3d at 1278. In other words, petitioners must show that the received vaccine
actually caused the alleged injury. Pafford, 451 F.3d at 1356. The sequence of cause
and effect need only be “logical and legally probable, not medically or scientifically
certain.” Knudsen, 35 F.3d at 548-49; accord. Capizzano v. Sec’y, HHS, 440 F.3d
1317, 1326 (Fed. Cir. 2006). Testimony from a treating physician may assist petitioner
in meeting her burden of proof under the second Althen prong. Capizzano, 440 F.3d at
1326.

        Petitioners contend Dr. Erenberg’s statement, indicating W.J.B. experienced
“some form of encephalopathic pattern of change” (Pet. Ex. 2, p. 2.), is sufficient proof
of a logical sequence of cause and effect, but this statement is far from being sufficient.
In that same report, Dr. Erenberg added “it would be impossible to figure out what [the
causal] event might have been.” Id.

        Although Dr. Erenberg expressed his opinion that W.J.B.’s encephalopathic
event “might have been due to a viral infection” in a “to whom it may concern letter”
written that same day, this general statement also is insufficient to implicate the MMR
vaccination. The MMR vaccine is a “combined live virus vaccine” (Pet. Reply at 4) as
petitioners contend, but Dr. Erenberg never mentions the MMR vaccination as a
possible cause or opines that it could have caused the “encephalopathic pattern of
change” to which he refers. Moreover, as also noted by the special master formerly
assigned to this case, Dr. Erenberg did not examine W.J.B. during this “encephalopathic
event” but 18 months later. See Order, issued Feb. 15, 2012, at 6.

      In addition to failing to satisfy the first Althen prong, petitioners have failed to
meet the requirements of the second prong.

        3. Lack of a Temporal Relationship.

       When proving that a vaccine was the cause of an injury, petitioner must also
show “a proximate temporal relationship between vaccination and injury.” Althen, 418
F.3d at 1278. Petitioner must prove “that the onset of symptoms occurred within a


Although the petitioners in this case were part of the OAP, they are not bound by the results in the Theory
1 test cases. Snyder, 2009 WL 332044, at *2-3. Nevertheless, they have advanced no new evidence—
indeed, no evidence at all—suggesting that the result reached in the Theory 1 test cases was incorrect. I
agree with the special master who earlier advised them that, without new evidence not considered in the
test cases supporting their causation theory, continuing to advance an MMR causation theory was
unreasonable. Order, issued Feb. 15, 2012, at 7.

                                                    20
timeframe for which, given the medical understanding of the disorder’s etiology, it is
medically acceptable to infer causation-in-fact.” de Bazan v. Sec’y, HHS, 539 F.3d at
1352. Failure to provide a proximate temporal relationship will result in a denial of
compensation. Id. at 1353.

       Petitioners’ expert, Dr. Cave, provided no evidence supporting vaccine causation
other than arguing that a comparison of the timing of W.J.B.’s viral illness (which she
claims occurred at least eight days before onset) makes it is “more likely than not that
the encephalopathic change in [W.J.B.] occurred because of the MMR (live viral)
vaccine given five days prior to the onset of the problem.” Pet. Ex. 15 at 2. However,
as the Federal Circuit has indicated, timing alone is not sufficient to prove causation.
Grant, 956 F.2d at 1148.

        Furthermore, as I previously stated, I do not accept petitioners’ assertions that
W.J.B.’s symptoms began within five to fifteen days of vaccination. I also do not
attribute great weight to Dr. Cave’s opinion as she lacks expertise in the specialties
relevant to the issues in this case. See Order, issued Feb. 15, 2012, at 1-2 (noting Dr.
Cave lacks expertise in developmental pediatrics, pediatric neurology, and pediatric
immunology).

       4. Conclusion on Actual Causation Claim.

      Petitioners have failed to establish any of the Althen factors by preponderant
evidence. Thus, petitioners have failed to prove that the MMR vaccine W.J.B. received
on January 4, 2000 actually caused his ASD.

                                    VI. Conclusion.

        Petitioners have asserted both that W.J.B. suffered a “Table” injury and that a
vaccine listed on the Table was the cause in fact of W.J.B.’s injuries but have failed to
prove either claim. After considering the record as a whole, I find that petitioners have
failed to establish entitlement to compensation. The petition is dismissed. The clerk
shall enter judgment accordingly.

IT IS SO ORDERED.
