                                   OPINION AND ORDER1

LETTOW, Judge.

       Petitioners, Rebecca and Randall Whitney, on behalf of their son, S.W., seek review of a
decision by a special master filed May 8, 2015, denying them an award under the National
Childhood Vaccine Injury Act of 1986, Pub. L. No. 99-660, § 311, 100 Stat. 3743, 3755 (1986)

       1
        In accord with the Rules of the Court of Federal Claims (“RCFC”), App. B (“Vaccine
Rules”), Rule 18(b), this opinion and order was initially filed under seal. By rule, the parties
were afforded fourteen days in which to propose redactions. No redactions were requested.
(codified, as amended, at 42 U.S.C. §§ 300aa-1 to -34) (“Vaccine Act”). The Whitneys allege
that the injection of their son with diphtheria-tetanus-acellular-pertussis (“DTaP”), Haemophilus
influenzae type b (“Hib”), inactivated polio (“IPV”), pneumococcal conjugate (“PCV”), and
rotavirus vaccines, administered on November 26, 2007, caused him to develop transverse
myelitis, a severe neurologic disorder. Pet’rs’ Mem. in Support of Mot. for Review of the
Special Master’s May 8, 2015 Decision (“Pet’rs’ Mem.”), ECF No. 116.2 The Secretary of
Health and Human Services (“the government”) acknowledges that S.W. suffered from an
episode of transverse myelitis and continues to have adverse effects from that condition but
argues that its cause is unrelated to administration of the vaccines. Response to Mot. for Review
(“Resp’t’s Mem.”), ECF No. 119.

        Transverse myelitis is an “off-Table” vaccine injury for which petitioners must establish
causation in fact by preponderant evidence. See 42 U.S.C. §§ 300aa-11(c)(1)(B), (C)(ii)(I),
300aa-13(a)(1); see also Althen v. Secretary of Health & Human Servs., 418 F.3d 1274, 1278
(Fed. Cir. 2005). The special master, applying the causation framework set out in Althen, denied
relief on the ground that the Whitneys failed to provide a logical sequence of cause and effect
between the vaccinations and transverse myelitis. See Whitney v. Secretary of Health & Human
Servs., No. 10-809V, slip op. at 14 (Fed. Cl. Spec. Mstr. May 8, 2015) (“Entitlement Decision”).
On review, the Whitneys aver that the special master’s decision was arbitrary and capricious and
his reasoning was contrary to relevant legal standards. The government responds that the special
master’s decision was in accordance with law and should not be set aside.




       2
         Transverse myelitis is a neurological disorder “characterized by the sudden onset of
rapidly progressive weakness of the lower extremities, accompanied by loss of sensation and
sphincter control, and often preceded by a respiratory infection.” John H. Menkes, Textbook of
Child Neurology (“Child Neurology”) 535 (Williams & Wilkins, 5th ed. 1995). For individuals
with transverse myelitis, “[t]he spinal cord is generally softened, with the most striking changes
occurring in the thoracolumbar region. . . . In the affected area, the spinal cord is often
completely necrotic; all nervous elements are lost, replaced by a cellular infiltrate or by
cavitation.” Id. at 535-36; see also Tr. 159:11-17 (Test. of Dr. Max Wiznitzer, an expert witness
called by the government). The transcript of the entitlement hearing before the special master
held on February 27, 2014 and March 7, 2014 will be cited as “Tr. __.”
         Very little information exists about the etiology of transverse myelitis because the
condition is rare. See Tr. 14:10-28 (Test. of Dr. Yuval Shafrir, an expert witness called by
petitioners). Researchers believe that transverse myelitis is caused by either a “direct infection
or by a parainfectious or postinfectious process.” Tr. 159:18-20 (Wiznitzer) (a parainfectious
process connotes a manifestation of an infectious disease caused by an immune response to an
infectious agent); see also Child Neurology at 536 (“The condition can be caused by . . .
autoimmune diseases, bacterial, viral, or spirochetal infections, and vascular malformations.”).

                                        BACKGROUND

                                    A. S.W.’s Medical History

         S.W. was born in July 2007. Pet’rs’ Ex. 1, at 1 (Medical Records from Michigan
Medical Pediatrics (June 8, 2011)).3 During the first four months of his life, S.W. was healthy,
and his pediatric records did not show any problems with development or illnesses. See id. Ex.
13, at 1-7 (Additional medical records from Michigan Medical Pediatrics). In mid-November of
2007, S.W. developed a mild upper respiratory infection, and other members of his family
displayed similar symptoms. Id. Ex. 2, at 255 (History and Physical Report by Dr. Beatrice
Guadalu Zepeda (Dec. 13, 2007)) & 264 (Consultation Report by Dr. George Fogg (Dec. 14,
2007)). His family did not take S.W. to a doctor, but tests conducted later indicated that he
probably then was suffering from a human herpesvirus 6 (“HHV-6”) infection. Entitlement
Decision at 2 n.3; see also Tr. 493:15-24 (Test. of Dr. Raoul Weintzen, an expert who also
testified on behalf of the government) (“I think he had an active HHV-6 infection at about
Thanksgiving when, by history, he had the upper respiratory infection we read about in the
medical record, the cold, runny nose, cough, and so on.”).4 On November 26, 2007, S.W. saw
his doctor for his four-month pediatric well-child visit. Pet’rs’ Ex. 13, at 5. At this appointment,
S.W. received the DTaP, Hib, PCV, IPV, and rotavirus vaccines. Id. Ex. 10, at 1 (Medical
Records from Dr. Donnie Reinhart (June 2, 2011)).

         Around December 6, 2007, S.W. showed signs of “some congestion and upper
respiratory symptoms,” but “[n]o nausea, vomiting, [or] diarrhea.” Pet’rs’ Ex. 2, at 261
(Physician Report (Dec. 13, 2007)). He also “appeared to be straining whenever he stooled.” Id.
Ex. 2, at 253 (History and Physical Reports (Dec. 13, 2007)). Experts testifying for both parties
testified that this condition indicated that S.W. may have developed neurologic problems at this
time. See Tr. 160:10-19 (Wiznitzer), 280:6-14 (Test. of Dr. James Oleske, an expert who also
testified on behalf of petitioners). A few days later, on December 12, 2007, S.W.’s mother
noticed that his legs were shaking, and she stayed “up with him . . . that night, rocking and
consoling him so he could get back to sleep.” Pet’rs’ Ex. 14, at ¶¶ 5-6 (Aff. of Rebecca Whitney
(Mar. 19, 2012)). The next day, on December 13, 2007, S.W.’s mother took him to see the
pediatrician, and she noted that S.W. had not been moving for two days and would scream when
waking up or when moving his legs. See id. Exs. 1, at 46 (General Visit Report (Dec. 13, 2007))
& 14, at ¶ 8. S.W. was observed to have decreased muscle tone in his lower extremities, “some

         HHV-6 is a “ubiquitous virus that is an etiologic agent of exanthema subitum[,] . . . a
short lived disease of infants and young children.” Dorland’s Illustrated Medical Dictionary
(“Dorland’s”) 664, 864 (Saunders Elsevier, 31st ed. 2007); see also Child Neurology at 428.
“Most healthy adults carry the virus and are asymptomatic.” Dorland’s at 864.

                                                 3
clonus,”5 and absent reflexes. Id. Ex. 1, at 46. Experts from the parties concurred that the
presence of clonus indicated that S.W. had been suffering from neurological problems for seven
to ten days. See Tr. 66:1-5 (Shafrir), 194:22 to 195:2 (Wiznitzer). Based on his symptoms, S.W.
was admitted to the emergency room and sent to the pediatric intensive care unit. Pet’rs’ Ex. 2,
at 261. His admission record stated a history similar to that provided by the pediatrician who
saw him. See id. Ex. 2, at 253-55. While S.W. was in the hospital, doctors took blood samples,
consulted with a neurologist, and performed a lumbar puncture to remove a sample of
cerebrospinal fluid. Id. Ex. 2, at 261. The latter sample showed inflammation in the spinal cord.
Id. Ex. 2, at 254; see also Entitlement Decision at 3.

         Doctors also ordered a series of MRIs and prescribed the antibiotic Rocephin to treat a
possible bacterial infection. Pet’rs’ Ex. 2, at 255; see also Tr. 97:8-25 (Shafrir). Prior to the
MRIs, a neurologist, Dr. Steven DeRoos, examined S.W. and reported that S.W. had “[n]o acute
febrile illness recently” and “agree[d] with the IV antibiotics until more information [wa]s
known.” Id. Ex. 2, at 267-68 (Consultation Report by Dr. DeRoos (Dec. 13, 2007)). On
December 13, 2007, S.W. had four MRIs. See id. Ex. 2, at 249-52 (Magnetic Resonance
Imaging Report (Dec. 13, 2007)). The images of the brain and lumbosacral spine were normal,
but the images of the cervical spine and thoracic spine showed that “[a] form of myelopathy in
the mid and lower cervical spinal cord exist[ed].” Id. at 250. According to the radiologist,
Dr. Edward Bok, the results “suggest[ed] the likelihood that this represent[ed] an immune
mediated disseminated myelitis, perhaps parainfectious in etiology.” Id. Ex. 2, at 250.

        The next day, on December 14, 2007, Dr. Fogg, a pediatric infectious disease specialist,
evaluated S.W. and noted that the child “[wa]s a four-month old . . . responding to high-dose
steroids” who received “DTaP, ITB, Hib, pneumococcal conjugate vaccine[s], and rotavirus
vaccine” on November 26, 2007. Pet’rs’ Ex. 2, at 264 (Consultation Report by Dr. Fogg (Dec.
14, 2007)). Dr. Fogg concluded that S.W.’s presentation of symptoms was “consistent with
acute disseminated encephalomyelitis ([‘]ADEM[’]).” Id. Ex. 2, at 265.6 For “infectious
triggers,” Dr. Fogg listed “viral (CMV, EBV, HSV, enterovirus and West Nile), bacterial
(Campylobacter, and mycoplasma), post vaccination reaction, or autoimmune disease” as
possibilities. Id. He made several recommendations that included a request for a polymerase
chain reaction (“PCR”) test to detect several types of pathogens, including HHV-6, which may
have been present in S.W.’s blood plasma. Id. Ex. 2, at 265-66. Finally, Dr. Fogg “agree[d]
with the plans for high-dose steroid therapy as directed by pediatric neurology” and stated that

         The term “clonus” is defined as “alternate muscular contraction and relaxation in rapid
succession” and “a continuous rhythmic reflex tremor initiated by the spinal cord below an area
of spinal cord injury.” Dorland’s at 379.
       6
         The term “encephalomyelitis” is defined as “inflammation involving both the brain and
the spinal cord.” Dorland’s at 621. ADEM is “a manifestation of an autoimmune attack on the
myelin of the central nervous system. . . . It occurs most commonly following an acute viral
infection.” Id.; see also Child Neurology at 521. Symptoms of ADEM include “fever, headache,
vomiting, and drowsiness progressing to lethargy[,] and coma, seizures, and paralysis may also
occur.” Dorland’s at 621.

                                                4
he would “report the possible post immunization adverse event to the [V]accine [A]dverse
[E]vent [R]eporting [S]ystem [(‘VAERS’)].” Id. Ex. 2, at 266 (emphasis added).7

        Following Dr. Fogg’s assessment and the resulting testing, lab results indicated that S.W.
had 4,100 copies of the HHV-6 per milliliter of plasma. Pet’rs’ Ex. 2, at 234 (General Lab
Reports (Dec. 14, 2007)). When “testing . . . show[ed] evidence of HHV-6 infection,” Dr. Fogg
wrote that “[the HHV-6 virus] or his immunizations could have been the trigger for his ADEM.”
Id. Ex. 2, at 166 (Progress Notes by Dr. Fogg (Dec. 17, 2007)) (emphasis added).8 A pediatric
neurologist who saw S.W. while he was in the hospital indicated that S.W. had “HHV[-]6
myelitis.” Id. Ex. 2, at 186 (Rounding Report (Dec. 21, 2007));9 see also Entitlement Decision at
5. S.W. remained in the hospital until December 21, 2007, when he was transferred to an
inpatient rehabilitation hospital, Mary Free Bed Hospital. Pet’rs’ Ex. 2, at 270-72 (Discharge
Documentation (Dec. 21, 2007)). S.W. remained at Mary Free Bed Hospital until January 2,
2008. Id. Ex. 5, at 47-50 (Physician Discharge Summary (Jan. 2, 2008)).

        On February 17, 2008, S.W. went to a neurology clinic for a follow-up appointment. See
Pet’rs’ Ex. 6, at 44 (Letter from Kim Shelanskey, family nurse practitioner, and signed by
Dr. DeRoos, to Dr. Stephen McMahon (Feb. 17, 2008)). Ms. Shelanskey recited the following
history of S.W.’s illness:

               [S.W.] is nearly 7-month-old male who was initially evaluated by
               Dr. Steven DeRoos during a hospitalization in December 2007 for
               transverse myelitis. At that time, [S.W.] presented with a 1-day
               history of decreased movement in his lower extremities. A full
               workup was completed in the hospital and included an MRI of the
               cervical spine which showed an abnormal signal running from the
               C2-C3 area in a rostrocaudal fashion to the upper thoracic spinal
               canal. This was thought to be a form of myelopathy. Infectious
               Disease was able to identify the HHV-6 virus as the causative
               agent.


       7
        “VAERS is a database maintained by the Center for Disease Control (‘CDC’) to compile
information from reports about reactions to immunizations listed on the Vaccine Injury Table, 42
U.S.C. § 300aa-14(a).” Analla v. Secretary of Health & Human Servs., 70 Fed. Cl. 552, 556
(2006).
       8
         At this time, “doctors listed [S.W.]’s diagnosis as ADEM. However, another doctor
(Dr. Adam Rush) disagreed with the diagnosis of ADEM because [S.W.]’s problem was limited
to his spine and did not affect his brain.” Entitlement Decision at 5 n.7 (citing Pet’rs’ Ex. 5, at
328). During the Entitlement Hearing, testifying neurologists agreed with the diagnosis of
transverse myelitis and not ADEM. See, e.g., Tr. 198:4-12 (Wiznitzer) (“[S.W.] had . . .
transverse myelitis.”). The diagnosis of transverse myelitis is not in dispute.
       9
         A neurologist also wrote “HHV-6 associated myelitis” in another medical note. Pet’rs’
Ex. 2, at 182 (Runding Report (Dec. 20, 2007)).

                                                 5
Id. (emphasis added).10 Ms. Shelanskey also noted that S.W. was “making nice gains and
continues to work with both occupational therapy and physical therapy through Mary Free Bed
[Hospital].” Id. Ex. 6, at 45. Dr. DeRoos, the neurologist “directly involved with formulating
the plan [for S.W.’s care,] . . . agree[d] with [Ms. Shelanskey’s] assessment.” Id. Two days
later, on February 19, 2008, S.W. saw a urologist, Dr. Brian Roelof, who noted that “[S.W.]
seems to be improving.” Id. Ex. 4, at 17 (Initial Visit Report by Dr. Roelof (Feb. 19, 2008)).
S.W.’s mother informed Dr. Roelof that she “thought he had acute viral myelitis secondary to a
virus or perhaps from his vaccinations.” See id.

        On February 22, 2008, S.W. had an appointment with a physiatrist,11 Dr. Rush, who had
previously cared for S.W. at Mary Free Bed Hospital. Mr. and Mrs. Whitney reported to
Dr. Rush that S.W. was experiencing a “dramatic return of strength and apparent sensation in his
bilateral[] lower limbs since [his last visit].” Pet’rs’ Ex. 5, at 327 (Final Report by Dr. Rush
(Mar. 4, 2008)). Mr. and Mrs. Whitney also informed Dr. Rush that they were “not planning at
this time for him to receive any more immunizations.” Id. Dr. Rush did not address the issue of
“immunization noncompliance” with S.W.’s parents at this appointment, but noted in his report
that:

               [i]t is incredibly important that like any other child, [S.W.] get his
               immunizations. I can only surmise at this point that his parents are
               reluctant to give him immunizations in the misguided belief that
               immunizations were the cause of his myelitis. I do not have any
               reason to believe this is the case, nor do I believe literature would
               [bear] that out. He should get all his immunizations.

Id. Ex. 5, at 328 (emphasis added). S.W. returned to see Dr. Rush a few months later, on June 4,
2008. S.W.’s mother reported to Dr. Rush that S.W. was suffering from the “occasional
(approximately daily) spasms of the lower limbs . . . [and] shaking episodes,” but they “[did] not
seem to cause him any discomfort.” Id. Ex. 5, at 325 (Final Report by Dr. Rush (June 13,
2008)). During this appointment, Dr. Rush “touch[ed] upon the issue of immunizations again
with S.W.’s mother.” Id. Ex. 5, at 326. According to Dr. Rush, Ms. Whitney felt “very strongly



       10
          Notably, the pediatric infectious disease specialist, Dr. Fogg, had not identified HHV-6
as the infectious agent, but rather listed HHV-6 along with S.W.’s immunizations as alternative
causes, see supra, at 5; see also Tr. 122:8-13 (Shafrir).
       11
          A physiatrist, or rehabilitation physician, is a medical doctor who has “completed
training in the medical specialty of physical medicine and rehabilitation.” American Academy of
Physical Medicine and Rehabilitation, What is a Physiatrist?, available at https://www.aapmr.
org/patients/aboutpmr/Pages/physiatrist.aspx. A physiatrist is responsible for “[d]iagnosing and
treat[ing] pain.” Id.; see also Dorland’s at 1464 (“Physiatry [is] the branch of medicine that
deals with the prevention, diagnosis, and treatment of disease or injury, and the rehabilitation
from resultant impairments and disabilities.”) (emphasis added).

                                                 6
at [that] point [in time] against resuming [vaccinations] now, though she did seem to leave the
door open for [S.W.] receiving his immunizations at some point in the future.” Id.

        On September 15, 2008, S.W. had an appointment with his neurologist, Dr. DeRoos.
Mr. and Mrs. Whitney were concerned that S.W. was experiencing seizures. Pet’rs’ Ex. 5, at 319
(Letter from Amy Tolliver, signed by Dr. DeRoos, to Dr. McMahon (Sept. 15, 2008)).
Dr. DeRoos concluded that the spells experienced by S.W. “could represent seizure[s]” and
recommended “obtain[ing] a repeat MRI.” Id. Ex. 5, at 320. The results from the repeat MRIs
were “unremarkable . . . with resolution of abnormal cord signal previously seen on the study of
12/13/2007.” Id. Ex. 6, at 53 (Magnetic Resonance Imaging Report (Jan. 12, 2009)).

         On June 23, 2010, about two and a half years after S.W.’s onset of transverse myelitis, he
was seen by a pediatrician, Dr. Lawrence Vogel, in a routine follow-up. Dr. Vogel summarized
events from when S.W. was approximately five months old, stating that “[S.W.] developed
irritability and constipation . . . about 2 to 2-1/2 weeks after receiving immunizations at the 4-
month mark.” Pet’rs’ Ex. 8, at 2 (Outpatient History and Physical Report (June 27, 2010)).
Dr. Vogel also recounted that “[S.W.]’s MRI was consistent with transverse myelitis” and that
doctors had found “herpes virus 6 isolated in [S.W.’s plasma] but whether or not this was related
to that or immunizations has never been clarified.” Id. Finally, Dr. Vogel recorded that S.W.’s
“[i]mmunizations were up-to-date as of [four] months, but because of the . . . potential
relationship [to] transverse myelitis[,] immunizations are being deferred at the current time.” Id.
Ex. 8, at 3.

        Shortly thereafter, on July 2, 2010, S.W. was seen by an occupational therapist, Karen
Gora, “for an evaluation for independent manual mobility and advice for facilitating independent
transfers.” Pet’rs’ Ex. 5, at 380 (Evaluation by Ms. Gora and signed by Dr. Rush (July 14,
2010)). In a “Letter of Medical Necessity” regarding S.W.’s orthopedic equipment needs,
Ms. Gora listed S.W.’s diagnosis as “Paraplegia, Myelitis (Reaction to an Immunization at age 4
months).” Id. (emphasis added). Based on her evaluation, Ms. Gora recommended the use of
orthopedic equipment, including a manual wheelchair and a custom seating system. Id. Ex. 5, at
382-83. Dr. Rush agreed with these recommendations. Id. Ex. 5, at 383.12

       S.W. has remained in therapy, but he continues to experience sequelae of transverse
myelitis. See generally Pet’rs’ Exs. 5, 24 (Updated Medical Records from Shriners Hospital for
Children), & 25 (Medical Records from Mary Free Bed Rehabilitation Hospital). The
complications include “secondary spastic paraparesis,13 neurogenic bladder and bowel,” and
sensory deficits in his legs. Id. Ex. 22, at 3 (Progress Notes (Dec. 5, 2013)). Since starting


       12
         More recently, on June 5, 2012, S.W. was seen by Dr. Allen Bragdon for a fever and
abdominal pain. Pet’rs’ Ex. 26, at 178 (Physician Report by Dr. Bragdon). Dr. Bragdon
reported that “[t]his is a 5-year-old child who unfortunately contacted transverse myelitis after
immunization at [four] months old. . . . Immunizations are not up to date [because S.W.’s]
[m]other opted not to do any further immunizations after the incident at 4 months old.” Id.

speech, uses a wheelchair or forearm crutches, and wears a diaper to school. Id. The transverse
myelitis has left S.W. with severe disabilities. See Tr. 116:17-24 (Shafrir) (“[T]ransverse

it’s a monophasic condition[] that goes away, [the patients] are left with very significant

                                  B. Special Master’s Decision

        The Whitneys filed their petition for compensation on November 22, 2010, alleging that
S.W. “suffered a demyelinating neurological disorder” after receipt of his childhood vaccines.
Pet’rs’ Pet. for Vaccine Compensation (“Pet.”) at 1, ECF No 1.14 Hearings in this case were
conducted by the special master in two sessions during February and March of 2014. At the
hearings, the parties were in agreement both about the chronology of events and that S.W.
suffered from transverse myelitis. See Entitlement Decision at 10. The parties disagreed
sharply, however, as to the cause or causes of S.W.’s transverse myelitis. The Whitneys relied
upon medical records, medical literature, and expert testimony of Dr. Yuval Shafrir and
Dr. James Oleske to show that S.W.’s vaccine inoculations caused his transverse myelitis. See
Pet’rs’ Post-Hearing Br., ECF No. 103.15 The government disagreed with the Whitneys’ theory
of causation, alleging that the treating physician’s statements and expert testimony cited by
petitioners were unpersuasive and failed to eliminate HHV-6 as the cause of S.W.’s condition.
See Resp’t’s Post-Hearing Br., ECF No. 104. To support its arguments, the government offered

discussing S.W.’s HHV-6 infection. Id.16

       The special master issued a decision denying compensation on May 8, 2015. Entitlement
Decision at 22. The special master concluded that the Whitneys had failed to prove that the
vaccines administered to S.W. on November 26, 2007 caused his transverse myelitis. Id. In so
holding, the special master applied the three-prong test set forth in Althen, 418 F.3d 1274, which
requires that a petitioner

       show by preponderant evidence that the vaccination brought about [the] injury by
       providing: (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.

Id. at 1278.

        The special master concluded that the Whitneys had carried their burden with respect to
prongs 1 and 3 of the Althen framework. Entitlement Decision at 11-13. However, upon
analyzing the second prong of Althen, i.e., relating to a logical sequence of cause and effect, the
special master determined that although the Whitneys “ha[d] presented a plausible case that the
vaccinations caused S.W.’s transverse myelitis, [this] belief . . . conflict[ed] with the opinions of
the doctors who treated [S.W.].” Id. at 22. As he put it, “the Whitneys have not identified even
one medical record in which a treating doctor expressed the opinion that a vaccination caused the
transverse myelitis.” Id. at 18-19. Additionally, according to the special master, the opinions
from Dr. Shafrir and Dr. Oleske were “thin and not persuasive” and failed to amount to
“something ‘more’” needed to meet the burden of showing actual causation. Id. at 19-21 (citing
Hibbard v. Secretary of Health & Human Servs., 698 F.3d 1355, 1358 (Fed. Cir. 2012)). After
discounting the medical records and expert testimony offered by the Whitneys, the special master
gave credence to the report written by Ms. Shelanskey and signed by Dr. DeRoos, stating:

               Dr. DeRoos . . . agreed with a parental report that said a specialist
               in infectious diseases identified the HHV-6 virus as causative. . . .
               The Whitneys are correct that there is no medical record from
               Dr. Fogg or any other specialist in infectious disease identifying

                the HHV-6 virus as the cause for the myelitis. Thus, there is a
                degree of hearsay in the record from Dr. DeRoos. Nevertheless,
                the circumstantial evidence supports the accuracy of the report to
                Dr. DeRoos.

Id. at 17 (citing Pet’rs’ Ex. 6, at 44-45). Also, the special master inferred that Dr. Fogg had
spoken to the Whitneys to inform them that their son’s transverse myelitis was caused by the
HHV-6 virus. Id. at 17-19 (citing Pet’rs’ Ex. 2, at 166, 234, & 264-66). The special master
ultimately concluded that “when the record is considered as a whole, the Whitneys have not met
their burden of proof for prong two.” Id. at 21.

       The Whitneys’ motion for review, filed on June 8, 2015, has been fully briefed, and a
hearing on the motion was held on July 22, 2015. See Hr’g Tr. on Pet’rs’ Mot. to Review (July
22, 2015).17 The case is now ready for disposition.

                                  STANDARDS FOR REVIEW

       Pursuant to the Vaccine Act, in reviewing a special master’s decision, the court may take
any one of the following three actions:

            (A) uphold the findings of fact and conclusions of law of the special
                master and sustain the special master’s decision,

            (B) set aside any findings of fact or conclusion[s] of law of the special
                master found to be arbitrary, capricious, an abuse of discretion, or
                otherwise not in accordance with law and issue its own findings of
                fact and conclusions of law, or

            (C) remand the petition to the special master for further action in
                accordance with the court’s direction.

                                           ANALYSIS

        Congress adopted the Vaccine Act to “establish a [f]ederal ‘no-fault’ compensation
program under which awards can be made to vaccine-injured persons quickly, easily, and with
certainty and generosity.” H.R. Rep. No. 99-908, at 3 (2d Sess. 1986), reprinted in 1986
U.S.C.C.A.N. 6334, 6334. A Vaccine Injury Table was originally established to provide an
expeditious means of compensating children and others who suffer vaccine related injuries.
Loving ex rel. Loving v. Secretary of Dep’t of Health & Human Servs., 86 Fed. Cl. 135, 141
(2009).18 For “Table injuries,” causation is conclusively presumed if a petitioner’s vaccine and
subsequent injury, or significantly aggravated condition, are listed on the Vaccine Injury Table.
See 42 U.S.C. § 300aa-11(c)(1)(C)(i); see also Hirmiz, 119 Fed. Cl. at 216. For “off-Table
injuries,” i.e., injuries or significantly aggravated conditions not found on the Vaccine Injury
Table, the petitioner must prove causation in fact by preponderant evidence. 42 U.S.C.
§§ 300aa-11(c)(1)(C)(ii), -13(a)(1)(A); see also Hirmiz, 119 Fed. Cl. at 216.

        Causation in fact is demonstrated by a petitioner who satisfies each of the three Althen
factors by preponderant evidence. Althen, 418 F.3d at 1278 (quoted supra, at 9). The Federal
Circuit has emphasized that “[a] persuasive medical theory is demonstrated by proof of a logical
sequence of cause and effect showing that the vaccination was the reason for the injury, the
logical sequence being supported by reputable medical or scientific explanation, i.e., evidence in
the form of scientific studies or expert medical testimony.” Id. (citation and internal quotations
omitted); see also Paluck ex rel. Paluck v. Secretary of Health & Human Servs., 104 Fed. Cl.
457, 470 (2012) (“[A] reliable theory of causation must be shown to be applicable to the facts of
the particular case at hand.”). For each Althen prong, “[e]vidence . . . may overlap with and be
used to satisfy another prong.” Hopkins ex rel. Hopkins v. Secretary of Dep’t of Health &


       18
          First put in place via statutory enactment, 42 U.S.C. § 300aa-14(a), the Vaccine Injury
Table has been periodically revised pursuant to notice-and-comment rulemaking under the
statutory authority of 42 U.S.C. § 300aa-14(c). The current version of the Vaccine Injury Table,
as amended, is set forth at 42 C.F.R. § 100.3.

Human Servs., 84 Fed. Cl. 517, 523 (2008). After a prima facie case of causation has been made
by the petitioner, “the burden shifts to the government to prove by a preponderance of the
evidence that the petitioner’s injury is due to factors unrelated to the administration of the
vaccine . . . .” de Bazan v. Secretary of Health & Human Servs., 539 F.3d 1347, 1352 (Fed. Cir.
2008) (citation and internal quotation omitted).

        The Federal Circuit has repeatedly cautioned that preponderant proof of causation need
not be shown with scientific certainty but rather by a demonstration that the vaccine more likely
than not caused the injury. See Althen, 418 F.3d at 1280 (“[T]he purpose of the Vaccine Act’s
preponderance standard is to allow the finding of causation in a field bereft of complete and
direct proof of how vaccines affect the human body.”); see also Moberly ex rel. Moberly v.
Secretary of Health & Human Servs., 592 F.3d 1315, 1322 (Fed. Cir. 2010) (“A petitioner must
provide a reputable medical or scientific explanation that pertains specifically to the petitioner’s
case, although the explanation need only be ‘legally probable, not medically or scientifically
certain.’”) (quoting Knudsen ex rel. Knudsen v. Secretary of Dep’t of Health & Human Servs., 35
F.3d 543, 548-49 (Fed. Cir. 1994)); Andreu, 569 F.3d at 1378 (“Requiring ‘epidemiologic
studies . . . or general acceptance in the scientific or medical communities . . . impermissibly
raises a claimant’s burden under the Vaccine Act.’”) (alteration in original) (quoting Capizzano,
440 F.3d at 1325-26).19 Therefore, a finding of causation in fact in vaccine cases can be “based
on epidemiological evidence and the clinical picture . . . without detailed medical and scientific
exposition on the biological mechanisms.” Knudsen, 35 F.3d at 549 (citing Jay v. Secretary of
the Dep’t of Health & Human Servs., 998 F.2d 979, 984 (Fed. Cir. 1993)). Nonetheless, this
standard for proving causation is not to be confused with a standard requiring only “possible” or
“plausible” causation. See Moberly, 592 F.3d at 1322.

       In proving causation, the special master is “entitled to require some indicia of reliability
to support the assertion of the expert witness.” Moberly, 592 F.3d at 1324 (citing Terran v.
Secretary of Health & Human Servs., 195 F.3d 1302, 1316 (Fed. Cir. 1999) (in turn citing
Daubert v. Merrell Dow Pharms., Inc., 509 U.S. 579 (1993))). In addition, the special master
may consider medical literature or epidemiological evidence in reaching an informed judgment
as to whether a particular vaccine inoculation caused a subsequent injury or significantly
aggravated condition. See LaLonde v. Secretary of Health & Human Servs., 746 F.3d 1334,
1339-40 (Fed. Cir. 2014).

        Here, S.W.’s transverse myelitis is not listed on the Vaccine Injury Table. Therefore, the
Whitneys must prove causation by preponderant evidence under the three-prong test set forth in
Althen. To this day, it has not been established with scientific certainty whether a vaccine, virus,
or other infectious agent caused S.W.’s transverse myelitis. See supra, at 7. Accordingly,
indirect and circumstantial evidence of cause and effect is quite important to this case. And,
while the present dispute concerns only the special master’s application of the second prong of


       19
         The requirement for preponderant evidence originates from the Vaccine Act itself:
“Compensation shall be awarded . . . to a petitioner . . . [who] has demonstrated by a
preponderance of the evidence the matters required in the petition by [42 U.S.C. § 300aa-
11(c)(1)].” 42 U.S.C. § 300aa-13(a)(1); see also Althen, 418 F.3d at 1279 & n.6.

                                                 12
the Althen framework, the evidence related to the first and third prongs is pertinent to an analysis
of the issues raised with regard to prong two.

       I.       Althen’s First Prong: A Theory Connecting Vaccine and Injury

         With regard to Althen’s first prong, the special master assumed that the Whitneys had met
their burden of proof because they had presented a plausible medical theory to explain how
vaccinations can cause transverse myelitis. The special master’s conclusion regarding prong one
is adequately supported by both the facts and the record. Through expert testimony and medical
literature, the Whitneys have demonstrated a biologically persuasive medical theory connecting
S.W.’s vaccinations, particularly the DTaP vaccine, to transverse myelitis.

        Dr. Shafrir explained that there are “different pathophysiologic mechanism[s] of how
[transverse myelitis] occur[s]” and that “[w]e see an immune stimulation, other infection, or
immunizations, and this creates an autoimmune reaction, which can be of different pathways.”
Tr. 16:10-16 (Shafrir).20 To explain the potential immunological pathways by which
vaccinations may induce autoimmunity and trigger the onset of transverse myelitis, Dr. Shafrir
pointed to a scientific article that discussed “[t]he mechanisms by which vaccines may induce
[transverse myelitis].” Pet’rs’ Ex. 16, at Tab D (N. Agmon-Levin, S. Kivity, M. Szyper-Kravitz,
& Y. Shoenfeld, Transverse myelitis and vaccines: a multi-analysis, 18 Lupus 1198-04 (2008)
(“Agmon-Levin study”)). The Agmon-Levin study outlined three pathways:

                The host’s response to a vaccine, originally generated to produce
                protective immunity, is similar to its response to an infectious
                invasion. Therefore, it is reasonable to assume that as infectious
                agents can induce autoimmunity, so can the recombinant or live
                attenuated antigens used for vaccination. Several mechanisms by
                which an infectious antigen may induce autoimmunity have been
                defined.

               Molecular mimicry between infectious antigens and self antigens is
                the most common mechanism.
               Epitope spreading, whereby invading antigens accelerate an
                ongoing autoimmune process by local activation of antigen
                presenting cells and over processing of antigens is another
                mechanism.
               Infectious agents, may induce autoimmunity via polyclonal
                activation of B lymphocytes or bystander activation which
                enhances cytokine production and further induce the expansion of
                auto reactive T-cells. The latter mechanism may be associated with
                post-infectious TM [transverse myelitis,] as IL-6 [inflammatory


        An autoimmune reaction is “characterized by a specific humoral or cell-mediated

               [cerebrospinal fluid] of TM patients.

Id. (emphasis in original); see also Tr. 23:21 to 24:16 (Shafrir).21

         Building upon Dr. Shafrir’s testimony, Dr. Oleske provided an immunological
explanation as to how a vaccine can induce transverse myelitis. See Tr. 333:3 to 335:23 (Oleske)
(testifying that vaccines can cause transverse myelitis through a cytokine response and stating
that “[S.W.], unfortunately, was one of those rare individuals . . . [whose] . . . immunological
response[] caused the transverse myelitis”). Dr. Oleske opined that “the multiple bacterial
and viral antigens of childhood vaccines, most often with an adjuvant used to stimulate an
immune and cytokine response, can be an extrinsic factor in adverse reactions to childhood
immunizations such as the [t]ransverse [m]yelitis . . . experienced by S.W.” Pet’rs’ Ex. 20, at 1
(Supplemental Medical Expert Report of Dr. James Oleske (Jan. 7, 2014)). According to
Dr. Oleske, his theory was consistent with the bystander activation theory outlined in the
Agmon-Levin study. Tr. 337:4 (Oleske).

        Notably also, several scientific publications identify the onset of transverse myelitis after
vaccinations. In a case series from the Johns Hopkins University Hospital and Kennedy Krieger
Institute, researchers collected clinical data from 47 patients between January 2000 and February
2004 who met the criteria for acute or remote transverse myelitis and were under the age of 18.

out of 47 children), the patient had received vaccinations or an allergy shot within 30 days of the
first symptom of transverse myelitis. Id. at 1476. The immunizations that were administered
included, inter alia, polio, hepatitis B, diphtheria-tetanus-pertussis, and Haemophilus influenzae.
Id.; see also Pet’rs’ Ex. 16, at 18 (Medical Expert Report of Yuval Shafrir, M.D. (Feb. 22,

Hopkins Case Series at 1476. Antecedent immunizations and illness were documented in eight
cases. Id. Because 28% of patients reported an immunization 30 days prior to the onset of
symptoms, the authors addressed a “potential causal link” between vaccinations and transverse
myelitis, commenting that “the large fraction of younger children affected, the current
recommended vaccination schedule for children, and the lack of any single vaccine association
within this group all undermine a potential cause link between vaccination and [acute transverse

myelitis.]”. Id. at 1479. According to Dr. Shafrir, the authors’ comment was “unfounded”
because their data are “statistically significant.” Pet’rs’ Ex. 16, at 18; see also Tr. 42:25, 41:6-7
(“We’re talking about a quarter of the series, which is a . . . very high number.”). Dr. Shafrir
testified that the researchers may have been “shocked by the number” and were concerned about
the “hot potato” that is vaccine politics. Tr. 41:4-5, 43:1 (Shafrir). Other case studies have also
documented transverse myelitis after vaccinations containing tetanus, diphtheria, and acellular or
cellular pertussis. See, e.g., Pet’rs’ Ex. 16, at Tab J (RMS Riel-Romero, Acute transverse
myelitis in a 7-month-old boy after diphtheria-tetanus-pertussis immunization, 44 Spinal Cord
688-91 (2006)), Tab K (Naser U.A.M.A. Abdul-Ghaffar & K.N. Achar, Brown-Sequard
Syndrome following Diphtheria and Tetanus Vaccines, 74 Trop. Doct. 74-75 (1994)), & Tab M
(E. Whittle & N.R. Robertson, Transverse myelitis after diphtheria, tetanus, and polio
immunization, Br. Med. J. 1450 (June 4, 1977)).

         Even though the foregoing case studies and the Johns Hopkins Case Series are not
definitive “proof of causality,” Tr. 54:18-19 (Shafrir); see also Tr. 168:6 to 168:22 (Wiznitzer),
the John Hopkins Case Series and other case studies demonstrate an “association” between
vaccines and the disorder. Pet’rs’ Ex. 16, at 20. Given the detailed explanation of the
mechanisms through which vaccines can cause transverse myelitis and the circumstantial
evidence from the case reports, Dr. Shafrir concluded that S.W.’s immunizations were “by far
the most likely cause for [S.W.’s] transverse myelitis.” Tr. 34:3-4 (Shafrir); see also Pet’rs’ Ex.
16, at 21 (“[I]t is much more likely than not that [S.W.]’s transverse myelitis was a result of an
immune process triggered by the vaccination.”). Dr. Oleske agreed. Tr. 337:23-24 (Oleske)
(testifying that S.W.’s vaccinations “more likely than not caused his transverse myelitis”).23

           The persuasiveness of this conclusion is bolstered by the admission of the government’s
expert, Dr. Weintzen. When asked about the immune-mediated mechanisms delineated in the
Agmon-Levin study, Dr. Weintzen answered that “all three of these pathophysiologic
approaches would apply equally to vaccine as to infection.” Tr. 570:2-4 (Weintzen) (emphasis
added); see also Tr. 510:17-20 (Weintzen) (“[A]ssuming vaccines do cause [transverse myelitis]
. . . I think there would be no reason to assume that the immune mechanisms would be
different.”). Although Dr. Weintzen ultimately believed that HHV-6 or another virus caused
S.W.’s transverse myelitis, Tr. 502:21 to 503:12 (Weintzen), he acknowledged a “hypothetical,
theoretical possibility that if you studied enough people, maybe you could find that, in fact, the
immune response to a vaccine can do what infections can do,” Tr. 572:11-14 (Weintzen).24 In


       23
          Given the rarity of the disorder in children (about one in a million), “the ability to
perform a prospective epidemiological study, which ideally would follow all the patients who
were immunized and see which of them will develop transverse myelitis, is practically
impossible.” Tr. 22:3-6 (Shafrir). “You [would] have to review . . . three [to] four million
patients.” Tr. 22:6-8 (Shafrir).
       24
         Dr. Weintzen testified that a circumstance in which he would tell a family that a DTaP
vaccine caused transverse myelitis was if “a neurosurgeon went in and biopsied the spinal cord
and a pathologist found pertussis antigen, or tetanus toxoid, or diphtheria toxoid, adherent to
components of his bone marrow.” Tr. 585:6-19 (Weintzen). Although Dr. Weintzen in effect
would have required a showing of causation equivalent to “scientific certainty,” such a
                                                 15
this respect, Dr. Weintzen joined Drs. Shafrir and Oleske in disagreeing with Dr. Wiznitzer’s
opinion that infections but not vaccines could cause transverse myelitis. See supra, at 14 n.21.

        Applying the pertinent evidentiary standard to the foregoing facts, the Whitneys have
established a persuasive “medical theory causally connecting the vaccination and the injury.”
Althen, 418 F.3d at 1278.

       II.     Althen’s Third Prong: A Proximate Temporal Relationship

       For the third prong of Althen, the special master found that the latency period between the
vaccinations and S.W.’s transverse myelitis was appropriate for the appearance of the disorder.
Entitlement Decision at 11-12. The court concurs.

         S.W. received the DTaP, Hep B, Hib, PCV, IPV, and rotavirus vaccinations on
November 26, 2007, and seventeen days later, on December 13, 2007, he was hospitalized for
neurological problems. See supra, at 3. All four experts who testified at the entitlement hearings
agreed that S.W. had been experiencing symptoms of his transverse myelitis as early as seven to
ten days before this initial hospitalization. Tr. 65:12-24 (Shafrir) (testifying that S.W.’s first
symptom of transverse myelitis was most likely constipation, which reportedly began ten days
before his admission to the hospital); Tr. 279:22 to 280:14 (Wiznitzer) (agreeing that S.W. had
some symptoms of transverse myelitis seven to ten days before hospitalization); Tr. 362:1-3
(Oleske) (“[At] seven to [ten] days, . . . there were probably early symptoms of the onset of the
transverse myelitis.”); Tr. 576:10-11 (Weintzen) (“I think the vaccine would be about ten days
before the onset of his constipation.”). Experts for both parties also testified that the temporal
relationship between the vaccinations and the manifestation of S.W.’s transverse myelitis was
medically appropriate. See, e.g., Tr. 33:1-7 (Shafrir) (testifying that the onset of S.W.’s
transverse myelitis was at an appropriate time for causation); Tr. 576:2-6 (Weintzen) (“Both the
vaccine and the respiratory infection at about Thanksgiving fall in perfect timing for what you
would expect for an immune system event to have been begun by that antigenic stimulation, on
either . . . side of the equation.”); see also Entitlement Decision at 11-12. The medical literature
provided by the Whitneys supports the testimony of the parties’ experts. See, e.g., Pet’rs’ Ex. 16,
at J (transverse myelitis documented in child who was given DTaP vaccine seventeen days
before he was admitted to hospital, and child was suffering from constipation prior to
admission).

        In these circumstances, the Whitneys have established that S.W.’s transverse myelitis
began within an appropriate time after the administration of his vaccinations. See Althen, 418
F.3d at 1278.

       III.    Althen’s Second Prong: A Logical Sequence of Cause and Effect

      The Whitneys raise objections to the special master’s conclusion that they failed to
demonstrate a logical sequence of cause and effect between S.W.’s vaccinations and the


heightened burden of proof in vaccine cases has been rejected by the courts. See, e.g., Moberly,
592 F.3d at 1322.
                                                16
transverse myelitis. See Pet’rs’ Mem. at 15-39. Their objections can be grouped into three
categories, namely (1) the support or lack of support for certain inferences drawn by the special
master, (2) the identification of a vaccine cause, or not, by treating physicians, and (3) the
implications of the treatment plan adopted for S.W. after the onset of transverse myelitis.

                                          A. Inferences

        As an initial matter, the Whitneys aver that the special master drew wholly impermissible
inferences from the factual record to support his conclusion that they failed to meet their burden
of proof for prong two. Pet’rs’ Mem. at 15-18. At onset of symptoms in December 2007, the
principal treating physician was Dr. Fogg, a pediatric infectious disease specialist. See Hr’g Tr.
6:23 to 7:3 (discussing Dr. Fogg’s role as an infectious disease specialist); see also Hr’g Tr.
22:23 to 23:1 (“Dr. Fogg was the infectious disease specialist who was consulted to try to figure
out what was leading to [S.W.’s condition] or whether there was an infectious disease.”). The
special master in his decision inferred that Dr. Fogg disclosed to the Whitneys that the HHV-6
virus was the causative agent of their son’s transverse myelitis. Entitlement Decision at 18
(“Dr. Fogg, in fact, told the Whitneys that the HHV-6 virus caused their son’s transverse myelitis
orally.”). No direct evidence supported the special master’s factual conclusion.

        Dr. Fogg initially listed as possible triggers viral, bacterial, post-vaccination, and
autoimmune causes for S.W.’s condition. Pet’rs’ Ex. 2, at 265. He ordered a polymerase chain
reaction test to detect pathogens in S.W.’s plasma, id. at 265-66, and that test showed evidence
of an HHV-6 infection, id. at 234. Thereafter, he wrote that “[the HHV-6 virus] or his
immunizations could have been the trigger for his ADEM.” Id. at 166. That circumstantial
evidence does not support the special master’s inference. See Hr’g Tr. 14:2-4 (“[T]here is no
record where Dr. Fogg explicitly says the HHV-6 vaccine was the cause of S.W.’s transverse
myelitis.”). Other circumstantial evidence points to a contrary conclusion. In February 2008,
two months after S.W.’s hospitalization, S.W. saw a urologist, Dr. Roelof, who took a history
from Ms. Whitney. Dr. Roelof reported that Ms. Whitney “state[d] that they thought [S.W.] had
acute viral myelitis secondary to a virus or perhaps from his vaccination. Pet’rs’ Ex. 4, at 17.
And, notably, the Whitneys steadfastly refused to allow S.W. to have further vaccinations, a
situation that a rehabilitation specialist, Dr. Rush, found to be problematic because, as he put it,
they were acting “in the misguided belief that immunizations were the cause of [S.W.’s]
myelitis.” Id. Ex. 5, at 328. The Whitneys’ belief had some basis, and nothing in the record
indicates that they were given medical advice to the contrary, from Dr. Fogg or any other treating
physician at the hospital. See Hr’g Tr. 27:18-20 (“[A]t some point the parents reached their own
conclusion that the vaccine was the cause.”).

        In short, the special master’s inference about what Dr. Fogg might have told the
Whitneys about causation is wholly unreasonable and lacks credible support in the medical
records. See Paluck, 786 F.3d at 1384-85 (finding that it was arbitrary and capricious for the
special master to make an inference that the treating physician had referred the petitioners to a
neurologist simply because he was “frustrated” with the petitioners).




                                                17
                      B. Medical Records from S.W.’s Treating Physicians

        The Whitneys contend that the special master incorrectly weighed certain medical reports
and statements from S.W.’s treating physicians. Pet’rs’ Mem. at 17-26. Essentially, the
Whitneys aver that the special master improperly discounted statements by treating physicians
that pointed to vaccine causation.

        1. Medical reports from Dr. Fogg on December 14 & 17, 2007.

         Dr. Fogg identified S.W.’s immunizations as a potential cause of his condition. On
December 14, 2007, one day after S.W. was admitted to the hospital, Dr. Fogg stated “that the
patient had his 4-month immunizations on 11/26/07. . . . Possible infectious triggers include
viral[,] . . . bacterial[,] . . . post vaccination reaction, or autoimmune disease . . . . I will report
the possible post immunization adverse event to [VAERS].” Pet’rs’ Ex. 2, at 264-66 (emphasis
added). Three days later, Dr. Fogg stated that “[the HHV-6 virus] or his immunizations could
have been the trigger . . . .” Id. Ex. 2, at 166 (emphasis added). The special master considered
these medical records to be “weak pieces of evidence.” Entitlement Decision at 16.25 He
concluded that “a treating doctor’s inclusion of a vaccine as a possible cause [did] not materially
support the petitioners’ argument.” Id.

         The Whitneys contend that the special master had no reasonable justification in
discounting the significance of Dr. Fogg’s medical notes. Pet’rs’ Mem. at 19-20. To support
their argument, the Whitneys rely on the Federal Circuit’s recent decision in Paluck, 786 F.3d
1373. In Paluck, the court of appeals held that petitioners “were entitled to rely on the
statements from [their child’s] physicians that his condition could be due to a ‘toxic . . . event’ as
evidence supporting a causal nexus between [his] vaccinations and his subsequent neurological
regression.” 786 F.3d at 1385 (emphasis added). The government counters that the circum-
stances here are different from those in Paluck because the special master in this case did not
disregard any probative medical statements. Resp’t’s Mem. at 7-8. The government argues that
in this instance, the evidence was insubstantial because Dr. Fogg listed “post vaccination
reaction” as a “possible” cause, not a probable or likely one. Id. at 8. The government therefore
contends that the special master’s application to this record evidence was “perfectly reasonable.”
Id.

        The government’s argument is not persuasive. Dr. Fogg was most directly responsible
for diagnosing S.W.’s condition at onset and making recommendations for testing and for S.W.’s
treatment immediately upon the child’s admission to the hospital. See Pet’rs’ Mem. Ex. 2, at
264-66; see also Hr’g Tr. 6:23 to 7:3. Dr. Fogg was in the “best position to determine whether a
logical sequence of cause and effect show[ed] that the vaccination was the reason for the injury.”
Andreu, 569 F.3d at 1375 (citations and internal quotations omitted); see also Moberly, 592 F.3d


        25
          The special master’s treatment of these medical records is inconsistent. While
classifying the evidence as “weak,” he also relied on the same records as “foundational points”
for drawing the inference that Dr. Fogg informed the Whitneys that the HHV-6 virus caused their
son’s transverse myelitis. See supra, at 17.

                                                   18
at 1323.26 While Dr. Fogg initially used the word “possible” when describing vaccine causation,
he coupled his initial diagnosis with the annotation that he would report this possibility to
VAERS. Pet’rs’ Mem. Ex. 2, at 265-6. The willingness of an infectious disease specialist to file
a VAERS report at the onset of a child’s symptoms is relevant evidence of causation. The
special master erred by neglecting to consider this probative piece of evidence. Cf. Dobrydnev v.
Secretary of Health & Human Servs., 566 Fed. Appx. 976, 984 (Fed. Cir. 2014), reh’g denied,
(Aug. 20, 2014), cert. denied, 135 S. Ct. 1560 (2015) (finding that the special master was not
required to give weight to a VAERS report filed 30 months after a vaccination when the
pediatrician who filed the report “[was] not an expert in [the] field,” and had “explicitly
defer[red] to the expert whose opinion ha[d] been rejected”).27

       2. Medical report from Dr. Rush on February 22, 2008.

        In a report from February 22, 2008, two months after the onset of S.W.’s condition,
Dr. Rush recommended that S.W. receive additional vaccinations. Dr. Rush indicated that he did
“not have any reason to believe . . . [that] immunizations were the cause of [S.W.’s] myelitis . . .
nor d[id] [he] believe literature would [bear] that out.” Pet’rs’ Mem. Ex. 5, at 328. The special
master described this statement as “remarkably strong and direct” evidence and stated that
Dr. Rush’s “recommendation for additional vaccinations, which would include additional doses
of the DTaP vaccine, further demonstrates his conviction that the vaccines did not harm [S.W.].”
Entitlement Decision at 17. The special master further noted that the Whitneys had not
challenged Dr. Rush’s qualifications to opine about causation and concluded that Dr. Rush was
“an unbiased and qualified doctor” since he “discounted the vaccinations as a cause for myelitis
without referring to the HHV-6 virus.” Id. at 17-18.

      The Whitneys challenge the special master’s assessment of Dr. Rush’s commentary for
two main reasons. Pet’rs’ Mem. at 18 n.25. First, the Whitneys suggest that Dr. Rush was not


       26
         In addition to Dr. Fogg, S.W. was seen during his hospitalization by at least one
neurologist. A neurologist made a handwritten sequacious annotation: “HHV-6 associated
myelitis.” Pet’rs’ Ex. 2, at 182. The special master considered that this note by a neurologist
was “ambiguous as to whether the doctor was stating that the virus caused the myelitis or the
virus simply preceded the myelitis.” Entitlement Decision at 17 n.17. However, he considered
the doctor’s later comment, “HHV[-]6 myelitis,” to be an indication of “a causal (as opposed to
simply temporal) relationship.” Id.; see also Pet’rs’ Ex. 2, at 182, 186.
       27
          Relatedly, the Whitneys dispute the special master’s conclusion that they failed to
“identif[y] even one medical record in which a treating doctor expressed the opinion that a
vaccination caused the transverse myelitis.” Entitlement Decision at 18-19 (emphasis added).
The special master’s determination is captious and untenable with respect to the evidence in the
record as a whole. See 42 U.S.C. § 300aa-13(a)(1). Certainly Dr. Fogg’s consideration that
S.W.’s vaccinations may have been a cause of his transverse myelitis and his decision to report
the adverse event to VAERS counts as “one medical record” expressing an opinion in support of
vaccine causation. See Pet’rs’ Ex. 2, at 166, 264-66; see also Pet’rs’ Mem. at 30 (citing a total of
six medical records from S.W.’s treating physicians that support a nexus between S.W.’s
vaccinations and subsequent transverse myelitis).
                                                19
qualified to render an opinion on causation. Dr. Rush is a medical doctor who specializes in
rehabilitation, see supra, at 6 n.11. He neither examined S.W. upon his admission to the hospital
nor was he involved in diagnosing S.W.’s condition or determining his initial treatment. Rather,
as a physiatrist, his services were aimed at the amelioration of symptoms and complications of
the disorder. See Pet’rs’ Ex. 5, at 325-29. His remarks about vaccine causation are far less
credible than the annotations made by Dr. Fogg, the infectious disease specialist who initially
treated S.W., or the opinions of the neurologists who testified as experts at the Entitlement
Hearing. That said, the Whitneys’ expert neurologist, Dr. Shafrir, described Dr. Rush’s report as
“extensive and thoughtful.” Id. Ex. 16, at 11. In addition, Dr. Rush correctly reasoned that S.W.
met the criteria for transverse myelitis, not ADEM. Id. Ex. 5, at 328 (“Please note that I do not
technically agree with the diagnosis of ADEM.”). Second, the Whitneys suggest that Dr. Rush’s
assessment was flawed due to his pro-vaccination point of view. Pet’rs’ Mem. at 18 n.25. As
shown in the medical report, Dr. Rush regretted his failure to address the issue of vaccination
when he met with S.W.’s parents because it was “incredibly important that like any other child,
[S.W.] get his immunizations.” Pet’rs’ Ex. 5, at 328 (emphasis added). Dr. Rush’s notes are
relevant evidence to be considered as part of the record as a whole, evaluated in light of his
medical background and focus and his evident emphasis on vaccinations notwithstanding
contraindications. See 42 U.S.C. § 300aa-13(a)(1).

       3. Medical reports signed by Dr. DeRoos on February 17, 2008 and Dr. Rush on July
          14, 2010.

        A report was prepared by a nurse practitioner, Ms. Shelanskey, on February 17, 2008,
about two months after S.W.’s admission to the hospital. Pet’rs’ Ex. 6, at 44. The report
addressed S.W.’s past history, discussed exam findings, and provided an assessment. Id. The
report noted that an infectious disease specialist, not named, had identified the HHV-6 virus as
the cause of S.W.’s condition. Id. (“Infectious Disease was able to identify the HHV-6 virus as
the causative agent.”). A neurologist, Dr. DeRoos, signed the report indicating that he agreed
with the nurse practitioner’s assessment. Id. The special master acknowledged that there was “a
degree of hearsay” in this statement; there was no record evidence that an infectious disease
specialist had established that a virus triggered S.W.’s transverse myelitis. Entitlement Decision
at 17. Regarding this report, Dr. Shafrir testified that “obviously[] the statement . . . is incorrect
[because Dr. Fogg] said either the vaccination or the HHV-6 [virus was the causative agent],
after the diagnosis of HHV-6 was known already.” Tr. 122:11-13 (Shafrir); see also Tr. 163:14-
17 (Wiznitzer) (“Yes, they did [consider the vaccines as a potential cause]. It was in the initial
notes that were there, that was a question that was raised.”); Tr. 329:6-11 (Oleske) (testifying
that Dr. Fogg never identified the sole cause of S.W.’s disorder and that the medical workup
“would not have allowed [the doctors] to come up with a sole cause.”). The special master
entirely overlooked expert testimony on this point. Instead, he found that the post-hospitali-
zation Shelanskey-DeRoos report had “some value as evidence that the treating doctors did not
consider the vaccine to be causative.” Entitlement Decision at 17-18.28




       28
         The special master improperly applied the same circumstantial evidence to credit this
record as he did to infer that Dr. Fogg had spoken with the Whitneys to inform them that the
                                                  20
         A report drafted by an occupational therapist, Ms. Gora, on July 14, 2010 evaluated
S.W.’s mobility, seating, and ability of transfer, and it included the therapist’s recommendation
that S.W. begin using a particular type of wheelchair. Pet’rs’ Ex. 5, at 380-83. Important to
this dispute, the first page of the document listed S.W.’s diagnosis as a “Reaction to an
Immunization,” and the last page was signed by Dr. Rush, who “concur[red]” with the
occupational therapist’s recommendation. Id. Ex. 5, at 380, 383. Although Dr. Rush signed this
report that identified S.W.’s condition as vaccine-induced, the special master did not afford this
piece of evidence any importance because it came over two years after Dr. Rush’s rehabilitative
assessment in February 2008, and it was “very unlikely that Dr. Rush changed his assessment of
the cause of [S.W.’s] transverse myelitis.” Entitlement Decision at 7 n.11; see also id. at 15. To
support this conclusion, the special master relied on the Whitneys’ own expert, Dr. Shafrir, who
“did not accept this relatively ministerial act as an expression of Dr. Rush’s views on the role
vaccinations played in [S.W.]’s illness.” Entitlement Decision at 15 (citing Tr. 126 to 128
(Shafrir)). Indeed, Dr. Shafrir testified that he did not “think that we should look at [this
document] as a determination of a diagnosis” because its purpose was to “get the child a
wheelchair.” Tr. at 127:12-15 (Shafrir). Similarly, the government’s expert, Dr. Wiznitzer,
testified that he suspected that Dr. Rush “[did]n’t even look at the first page [of the report],” but
simply signed the document because S.W. needed the wheelchair “irrespective of what the
diagnosis [wa]s.” Tr. 164:21 to 165:9 (Wiznitzer).

         The Whitneys fault the special master for crediting the post-hospitalization Shelanskey-
DeRoos report while “wholly discount[ing]” the later Gora-Rush report. Pet’rs’ Mem. at 21-26.
The Whitneys argue that “if the special master purports to use expert testimony to discount
medical records helpful to petitioners, he should do so for all records in question.” Id. at 26.
And, indeed, the special master credited the Shelanskey-DeRoos report despite the “level of
hearsay” within the report, which hearsay was contraindicated by other portions of the medical
record, while relying on expert testimony to discredit the Gora-Rush report that supported the
Whitneys’ theory of vaccine causation. Entitlement Decision at 15-17. The Whitneys claim that
“[i]t is clear that the special master desired a certain result, and misconstrued the evidence in
order to reach that result.” Pet’rs’ Mem. at 26. There are indicia that the special master did what
the Whitneys claim, but the dispute over the special master’s treatment of the Shelanskey-
DeRoos and the Gora-Rush reports focuses on records generated in both instances after diagnosis
and testing, and this in a sense constitutes an argument over evidence secondary to the treating
physicians’ contemporaneous notes.

                                    C. S.W.’s Treatment Plan

         The medical records reveal that S.W. was initially treated with high-dose steroids, not
anti-viral drugs. Pet’rs’ Ex. 2, at 264 & 266. The Whitneys argue that S.W.’s treatment course
of steroids is salient evidence that “[S.W.] was experiencing an inflammatory, immune-mediated
process.” Pet’rs’ Mem. at 26-28. They contend that the special master abused his discretion by
failing to consider this treatment plan as evidence in support of vaccine causation. Id.


HHV-6 virus triggered S.W.’s condition. See supra, at 17; see also Entitlement Decision at 17-
18.

                                                 21
         Contrary to the Whitneys’ contention, the special master did consider S.W.’s treatment
plan, acknowledging that there was a dispute among the testifying experts “whether [S.W.’s]
doctors responded appropriately to the [HHV-6] positive PCR test.” Entitlement Decision at 5
n.6. He concluded that “this issue is extraneous to determining whether the vaccines caused
[S.W.]’s transverse myelitis,” reasoning that, as Dr. Weintzen testified, steroid therapy is a
proper treatment for either an immune-mediated reaction to vaccines or an immune-mediated
reaction to a prior infection with the HHV-6 virus. Id.; see Tr. 501:10 to 502:20 (Weintzen)
(discussing steroid treatment to prevent nerve tissue damage in the spinal cord by minimizing an
immune response); see also Resp’t’s Mem. at 13-14. When S.W. was admitted to the hospital,
he was in the “convalescent phase” of the HHV-6 infection. See Tr. 499:25, 501:19 to 502:12
(Weintzen) (indicating that the HHV-6 infection was convalescing based on the number of
copies of viral DNA found in S.W.’s plasma). In essence, there were viral particles in S.W.’s
blood, but his immune system had responded to the infection. Tr. 494:15-24, 593:24 to 594:2
(Weintzen) (“[S.W.] was in the recovery stage of his HHV-6 [infection] clearly.”); see also Hr’g
Tr. 31:12-14 (“[H]is immune system had kicked in and was starting to fight off the virus.”).29
Dr. Weintzen testified that he would not have ordered anti-viral drugs at that point in time
because S.W.’s “immune system [had] already responded” to clear the virus. Tr. 578:4-12
(Weintzen). However, a powerful anti-inflammatory medication, such as steroid therapy, would
suppress an immune-mediated reaction and prevent injury to S.W.’s spinal cord, regardless of the
trigger.

        The Whitneys disregard Dr. Weintzen’s testimony and rely on the testimony of
Dr. Wiznitzer, who opined “that if [S.W.] had a direct viral myelitis with HHV-6, [he] would
worsen before he got better if he did not receive the anti[-]viral medication.” Pet’rs’ Mem. at 27
(emphasis added) (citing Tr. 281:23 to 282:1 (Wiznitzer)). The Whitneys further rely on the
testimony of Dr. Oleske, who testified that treatment of high-dose steroids is an “indication that
the treating physicians and specialists that were seeing [S.W.] certainly didn’t consider this an
active HHV-6 infection, otherwise they would have treated him with anti[-]viral drugs and been
cautious with high-dose steroids.” Tr. 325:14-21 (Oleske). As discussed above, the steroid
treatment only proves that S.W.’s doctors thought he was having an immune-mediated reaction.
It “says nothing about what triggered it.” Resp’t’s Mem. at 16; see also Hr’g Tr. 18:2-7
(conceding that it was “correct” that the steroid treatment was ambiguous as to cause).

        As a result, the testimony about treatment is not particularly helpful either to prove or
disprove a vaccine cause. Among other things, the HHV-6 virus did not directly invade S.W.’s
spinal cord, thereby causing inflammation. Entitlement Decision at 12-13 (“[L]ittle evidence
supports a direct invasion theory”); see also Tr. 501:23 to 502:1 (Weintzen) ([I]t’s not active . . .
virus growing in the spinal cord, it’s the immune response that somehow as an innocent
bystander hurt[s] an organ of the body, in this case the spinal cord.”). Rather, as discussed


       29
          In the case of HHV-6, “before the immune response [is triggered],” the virus initially
has an “unrestricted capability of growing.” Tr. 500:7-9 (Weintzen). The convalescent phase
refers to the later stage of the infection when the “immune response [has] mature[d] more,” thus
inhibiting viral replication “so that . . . over time the concentration of virus in blood drops.” Tr.
500:13-18 (Weintzen).

                                                 22
supra, either a post-vaccination event or the HHV-6 virus led to S.W.’s transverse myelitis by
triggering autoimmunity. See Entitlement Decision at 13; see also Agmon-Levin study
(outlining three pathways that induce autoimmunity). Accordingly, “it was reasonable for the
[s]pecial [m]aster to conclude that he could not draw any inferences about causation from
[S.W.]’s treatment.” Resp’t’s Mem. at 14.

       IV.     Synopsis

        With regard to prongs 1 and 3 of the Althen framework, the special master properly
weighed the evidence of record and made determinations in accord with law. Petitioners
prevailed on those prongs. When analyzing the second prong of Althen, however, the special
master made findings and conclusions that were contrary to the evidence of record and thus were
arbitrary, capricious, and an abuse of discretion. The special master drew the unsupported and
impermissible inference that Dr. Fogg informed the Whitneys that only the HHV-6 virus, and not
the vaccinations, triggered their son’s transverse myelitis. The special master also committed
error when he discounted the diagnostic medical reports by Dr. Fogg and stated that the
Whitneys had not produced even one medical record to support a nexus between S.W.’s
transverse myelitis and the administration of the vaccines. Finally, the special master acted
arbitrarily and capriciously by overly crediting the post-hospitalization Shelanskey-DeRoos
report that contained hearsay not otherwise supported by the medical records, while discrediting
the Gora-Rush report. The special master nonetheless was on a solid footing in determining that
evidence regarding S.W.’s steroid therapy was not particularly helpful on the issue of causation.

                                        CONCLUSION

       For the reasons stated, the Whitneys’ motion for review is GRANTED, the special
master’s decision of May 8, 2015 denying compensation is VACATED, and the case is
REMANDED to the special master for further proceedings. The court sets aside the findings of
the special master as to prong 2 of Althen, but makes no affirmative findings of its own.

        In this instance, the respective burdens of proof and persuasion to be borne by the parties
may become critical to the outcome. There is the distinct possibility that the Whitneys have, or
will establish on remand, a prima facie case of causation under the Vaccine Act. The
government can overcome the prima facie case by showing by preponderant evidence that
S.W.’s condition “is due to factors unrelated to the administration of the vaccine.” Deribeaux ex
rel. Deribeaux v. Secretary of Health & Human Servs., 717 F.3d 1363, 1367 (Fed. Cir. 2013);
see also de Bazan, 539 F.3d at 1352. It therefore may be incumbent upon the special master
explicitly to consider whether the Whitneys have made a prima facie showing, and, if so, then
whether the government can by a preponderance of the evidence demonstrate that S.W.’s
transverse myelitis was caused by the HHV-6 infection, a factor unrelated to vaccination. See 42
U.S.C. §§ 300aa-13(a)(1)(A)-(B).

       This may well be a case in which it is appropriate to obtain testimony from Dr. Fogg and
other physicians who treated S.W. upon hospitalization, to gain a better understanding of the




                                                23
most relevant medical records.30 Correlatively, one or both of S.W.’s parents might testify as to
what, if anything, Dr. Fogg told them at the time of his diagnosis.

       It is so ORDERED.

            The Federal Circuit has commented that

                 [i]n most instances, however, it is both inadvisable and unnecessary
                 to subpoena the testimony of treating physicians. It would not be in
                 the public interest for the specter of a subpoena to provide physicians
                 with a disincentive to treat a vaccine-injured patient or to cause them
                 to be less than forthright in creating medical records assessing
                 the relationship between a vaccine and a patient’s injury. The
                 submitted documentary evidence can, under most circumstances,
                 provide adequate insight into the medical opinions of treating
                 physicians, and there is little need to subject them to cross-
                 examination in federal court.

Andreu, 569 F.3d at 1383 (citing Cucuras v. Secretary of Health & Human Servs., 993 F.2d
1525, 1528 (Fed. Cir. 1993)). This appears to be the exceptional case. The special master
apparently considered that possibility in asking the parties “whether information[, i.e.,
testimony,] should be sought from [S.W.’s] treating doctors.” Entitlement Decision at 18 n.18.
