DECISION1
On May 18, 2017, petitioner, Gina Kidwell, filed a petition under the National
Childhood Vaccine Injury Act, 42 U.S.C. § 300aa-10-34 (2012)2, alleging that she
suffered an episode of syncope following her receipt of an influenza (“flu”) vaccination
on October 13, 2015. Petitioner was driving at the time of the alleged syncope and was
involved in a motor vehicle accident, resulting, she further alleges, in injuries that
persisted for more than six months.3 Accordingly, petitioner alleges that the syncope,
1 Because this decision contains a reasoned explanation for the special master’s action in this case, it will
be posted on the United States Court of Federal Claims’ website in accordance with the E-Government
Act of 2002. See 44 U.S.C. § 3501 note (2012) (Federal Management and Promotion of Electronic
Government Services). This means the decision will be available to anyone with access to the
Internet. In accordance with Vaccine Rule 18(b), petitioner has 14 days to identify and move to redact
medical or other information the disclosure of which would constitute an unwarranted invasion of privacy.
If the special master, upon review, agrees that the identified material fits within this definition, it will be
redacted from public access.
2Throughout this decision, references to “§300aa” will refer to the relevant sections of the National
Childhood Vaccine Injury Act.
3 Petitioner is never more specific in her pleadings than to characterize her persistent symptoms as
headache and unsteadiness in her walk. (ECF No. 1, p. 2; ECF. No. 46, p. 2.) However, her medical
records reference her post-accident condition as post-concussion syndrome. (E.g. Ex. 5, pp. 21-22.) For
ease of reference, this decision refers in some instances to petitioner’s post-accident injuries as a post-
concussion syndrome; however, as discussed below, the question of whether petitioner’s post-accident
condition represented a post-concussion syndrome is not reached.
1
subsequent accident, and resulting injuries, were all caused by the flu vaccine. For the
reasons set forth below, I conclude that petitioner is not entitled to compensation.
I. Applicable Statutory Scheme
Under the National Vaccine Injury Compensation Program, compensation
awards are made to individuals who have suffered injuries after receiving vaccines. In
general, to gain an award, a petitioner must make a number of factual demonstrations,
including showing that an individual received a vaccination covered by the statute;
received it in the United States; suffered a serious, long-standing injury; and has
received no previous award or settlement on account of the injury. Finally – and the key
question in most cases under the Program – the petitioner must also establish a causal
link between the vaccination and the injury. In some cases, the petitioner may simply
demonstrate the occurrence of what has been called a “Table Injury.” That is, it may be
shown that the vaccine recipient suffered an injury of the type enumerated in the
“Vaccine Injury Table,” corresponding to the vaccination in question, within an
applicable time period following the vaccination also specified in the Table. If so, the
Table Injury is presumed to have been caused by the vaccination, and the petitioner is
automatically entitled to compensation, unless it is affirmatively shown that the injury
was caused by some factor other than the vaccination. § 300aa-13(a)(1)(A); § 300aa-
11(c)(1)(C)(i); § 300aa-14(a); § 300aa-13(a)(1)(B).
As relevant here, the Vaccine Injury Table lists “vasovagal syncope” as a
compensable injury if it occurs within one hour of administration of an influenza vaccine.
§ 300aa-14(a) as amended by 42 CFR § 100.3. Table Injury cases are guided by a
statutory “Qualifications and aids in interpretation” (“QAI”), which provides more detailed
explanation of what should be considered when determining whether a petitioner has
actually suffered an injury listed on the Vaccine Injury Table. § 300aa-14(a). To be
considered a Table “syncope” petitioner must show that her injury fits within the
following definition:
Vasovagal syncope (also sometimes called neurocardiogenic syncope)
means loss of consciousness (fainting) and postural tone caused by a
transient decrease in blood flow to the brain occurring after the
administration of an injected vaccine. Vasovagal syncope is usually a
benign condition but may result in falling and injury with significant sequela.
Vasovagal syncope may be preceded by symptoms such as nausea,
lightheadedness, diaphoresis, and/or pallor. Vasovagal syncope may be
associated with transient seizure-like activity, but recovery of orientation
and consciousness generally occurs simultaneously with vasovagal
syncope. Loss of consciousness resulting from the following conditions will
not be considered vasovagal syncope: organic heart disease, cardiac
arrhythmias, transient ischemic attacks, hyperventilation, metabolic
conditions, neurological conditions, and seizures. Episodes of recurrent
syncope occurring after the applicable time period are not considered to be
sequela of an episode of syncope meeting the Table requirements.
2
42 CFR § 100.3(c)(13).
Petitioner did not initially indicate in her petition whether she was pursuing her
claim as a Table Injury. (ECF No. 1.) However, she later filed an amended petition
asserting a Table Injury of vasovagal syncope. (ECF No. 46.) In her closing briefs,
petitioner also characterized her injury as a Table Injury. (ECF Nos. 78, 79.)
Alternatively, if no injury falling within the Table can be shown, the petitioner
could still demonstrate entitlement to an award by instead showing that the vaccine
recipient’s injury or death was caused-in-fact by the vaccination in question. § 300aa-
13(a)(1)(A); § 300aa-11(c)(1)(C)(ii). In that regard, petitioner did also file an expert
report to support her claim. To successfully demonstrate causation-in-fact, petitioner
bears a burden to show: (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 proximate temporal relationship between
vaccination and injury. Althen v. Sec’y of Health & Human Servs., 418 F.3d 1274, 1278
(Fed. Cir. 2005)
For both Table and Non–Table claims, Vaccine Program petitioners bear a
“preponderance of the evidence” burden of proof. Section 13(1)(a). That is, a petitioner
must offer evidence that leads the “trier of fact to believe that the existence of a fact is
more probable than its nonexistence before [he] may find in favor of the party who has
the burden to persuade the judge of the fact's existence.” Moberly v. Sec’y of Health &
Human Servs., 592 F.3d 1315, 1322 n.2 (Fed. Cir. 2010); see also Snowbank Enter. v.
United States, 6 Cl. Ct. 476, 486 (1984) (mere conjecture or speculation is insufficient
under a preponderance standard). Proof of medical certainty is not required. Bunting v.
Sec'y of Health & Human Servs., 931 F.2d 867, 873 (Fed. Cir. 1991). In particular, a
petitioner must demonstrate that the vaccine was “not only [the] but-for cause of the
injury but also a substantial factor in bringing about the injury.” Moberly, 592 F.3d at
1321 (quoting Shyface v. Sec'y of Health & Human Servs., 165 F.3d 1344, 1352–53
(Fed. Cir. 1999)); Pafford v. Sec'y of Health & Human Servs., 451 F.3d 1352, 1355
(Fed. Cir. 2006). A petitioner may not receive a Vaccine Program award based solely
on his assertions; rather, the petition must be supported by either medical records or by
the opinion of a competent physician. § 300aa-13(a)(1).
II. Procedural History
As noted above, petitioner initiated this case on May 18, 2017, alleging that she
suffered a syncopal episode that resulted in an auto accident and further injuries. (ECF
No. 1.) She filed supporting medical records marked as Exhibits 1-11 on May 24, 2017.
(ECF Nos. 7-8.) After an initial review, respondent requested further records and
Exhibits 12-19 were subsequently filed over the course of several months. (ECF Nos.
16, 19, 22, 28.)
Respondent filed his Rule 4 report on October 15, 2018, recommending
compensation be denied and the petition dismissed. (ECF No. 32.) Respondent noted
the lack of a Table Injury allegation, but also disputed that petitioner suffered a syncopal
3
episode and further contended that the timing of the event was unclear. Petitioner
subsequently filed a vehicle accident report (Ex. 20), an affidavit by petitioner (Ex. 21),
and neuropsych records (Ex. 22). (ECF Nos. 35, 40, 43.) Petitioner filed an amended
petition on April 8, 2019, specifically adding the allegation that she experienced a Table
Injury of vasovagal syncope. (ECF No. 46.) On June 25, 2019, petitioner filed an
expert report by neurologist Marcel Kinsbourne, M.D. (ECF No. 50; Ex. 23.)
On August 29, 2019, this case was reassigned to my docket. (ECF No. 53.)
Respondent subsequently filed a responsive expert report by neurologist Peter
Donofrio, M.D., on November 1, 2019. (ECF No. 55; Ex. A.) A video fact hearing was
subsequently held on January 30, 2020. (ECF No. 62.) Petitioner was the only witness.
(Id.)
During the hearing, additional evidence was identified. Petitioner then filed her
insurance claim relative to her auto accident (Ex. 25), an affidavit by her daughter
regarding a separate falling incident discussed during the hearing (Ex. 26), updated
primary care records by Dr. Connie Mercer (Ex. 27), and an affidavit by an eye witness
to the auto accident (Ex. 28). (ECF Nos. 69, 73.)
Thereafter, I advised the parties that pursuant to Vaccine Rule 8(d) I intended to
resolve this case on the basis of written submissions and set a briefing schedule
requiring simultaneous briefs.4 (ECF No. 74.) Neither party objected; however, in a
joint motion to amend the schedule, the parties advised of additional outstanding
medical records and requested that their briefs be due after the filing of the outstanding
records. (ECF No. 75.) Petitioner subsequently filed additional medical records marked
as Exhibits 29-31. (ECF No. 76.)
On December 21, 2020, the parties filed simultaneous briefs in support of their
respective positions. (ECF No. 77-78.) Petitioner filed a brief responding to
respondent’s brief on January 21, 2021. (ECF No. 79.) This case is now ripe for
resolution on the written record.
III. Factual History
A. Petitioner’s prior medical history
Petitioner has a history of depression and hyperlipidemia. (Ex. 4, p. 1.)
Petitioner was also previously evaluated for syncope. On June 12, 2012, petitioner
visited the emergency room with multiple medical complaints including anxiety and
syncope. (Ex. 15, p. 45.) Petitioner reported experiencing aura and then flashing lights.
4 Special masters “must determine that the record is comprehensive and fully developed before ruling on
the record.” Kreizenbeck v. Sec’y of Health & Human Servs., 945 F.3d 1362, 1366 (Fed. Cir. 2020)
(citing Simanski v. Sec’y of Health & Human Servs., 671 F.3d 1368, 1385 (Fed. Cir. 2012); Jay v. Sec’y of
Health & Human Servs., 998 F.2d 979, 983 (Fed. Cir. 1993.)); see also Vaccine Rule 8(d); Vaccine Rule
3(b)(2). The parties must have a full and fair opportunity to present their case and develop a record
sufficient for review. Id.
4
(Id.) On June 20, 2012, petitioner saw Dr. Ganesh Chari for further evaluation of her
syncopal episode, where she reported that she saw flashing lights followed by nausea.
(Ex. 12, p. 108.) Additionally, petitioner had a follow up appointment on July 18, 2012
for syncope. (Id. at 106.) According to petitioner there were no further syncopal
episodes.
On May 20, 2013, petitioner visited Tampa Bay Optometric Group because she
had issues with seeing “squares” followed by nausea and headache. (Ex. 12, p. 92.)
Petitioner left a message for her primary care physician (“PCP”), Dr. Daniel Terrone that
she experienced an episode where she saw squares in front of her eyes, lost her
balance, and became nauseous. (Ex. 15, p. 93.) A couple of months thereafter in
September, petitioner reported feeling dizzy and nauseated. She felt she was having
problems with her inner ear, and requested seeing a specialist. (Id. at 99.)
Petitioner then established care with a new PCP, Dr. David Herndon, on January
6, 2015 and reported her inner ear problems. (Ex. 4, p. 1.) Petitioner reported that she
felt slightly dizzy with some nasal drip. (Id.) On January 20, 2015, petitioner returned to
see Dr. Herndon for pain management. (Id. at 10.) She reported nausea and ringing in
her ear. Petitioner wanted to see an ENT specialist. (Id.) Dr. Herndon diagnosed
petitioner with subjective tinnitus and referred her to a specialist for evaluation. (Id. at
12.)
On January 26, 2015, petitioner saw Dr. Michael Sakellarides with complaints of
allergy to smoke, recent ringing in both ears, postnasal drip, and lightheaded due to
smoke. (Ex. 8, p. 3.) Petitioner was diagnosed with benign paroxysmal vertigo and
referred for vestibular studies for dizziness and audiogram for ringing in ears. (Id. at 5.)
On October 13, 2015, petitioner saw Dr. Steven Willis regarding her back pain.
(Ex. 4, p. 61.) And additionally, on the same day, petitioner visited Dr. Herndon for
follow up. (Id. at 64.) Her vital signs were recorded at Dr. Herndon’s office at about
3:43pm. (Id. at 65.) During this visit, petitioner was given the flu vaccine at issue in this
case in her right deltoid. (Id. at 68.) The exact time of vaccination was not
documented. She was 80 years old at the time.
B. October 13, 2015 auto accident
After departing Dr. Herndon’s office, petitioner was involved in an auto accident.
(Ex. 20.) According to the official Florida Traffic Crash Report, at approximately 4:30pm
petitioner lost control of her vehicle, entered a parking lot to the right and collided with a
parked car. (Id. at 2-3.) During the hearing, petitioner described the accident as
follows: “I put my foot on the gas pedal. And then I’m going and all of a sudden, oh, my
god, I thought my brakes aren’t working. I kept – I thought it was the brakes. I kept my
foot all the way down for the gas pedal. And I kept going, I said, I’m going to – there’s
trees all around me on both sides. I’m going to get killed. I know I’m going to die. After
that I remember nothing else. Nothing.” (Tr. 10-11.) Petitioner indicated the next thing
she remembered was the airbag deploying. (Tr. 11-12.) She indicated that she fell to
the ground when she initially exited the vehicle. (Tr. 12.) Petitioner repeated
5
substantially the same description multiple times during the hearing. (Tr. 20, 45-46, 52-
54.)
Following the accident, the most contemporaneous third-party observation of
petitioner’s state comes from the affidavit testimony of fact witness Timothy Skarka.
(Ex. 28.) He was the individual who first helped petitioner out of the car following her
accident. In relevant part he explained that “[a]fter she hit the car her foot was still on
the gas. I ran over and opened the door and took her foot off the gas and turned the key
off. She did not get out of the car for a few minutes. She seemed confused. I suggested
calling an ambulance because I thought she might have suffered a concussion. She
said she was alright and did not want an ambulance.” (Id. at 1.) Mr. Skarka did not
indicate that he observed petitioner in a state of unconsciousness5 and did not
corroborate petitioner’s recollection of falling over when she exited the vehicle.
(Compare Ex. 28 and Tr. 11-12, 14.)
Pasco County Fire Rescue arrived at the scene by 4:39pm. (Ex. 14, p. 1.) Upon
examination, they confirmed petitioner to be alert and oriented (x4) and recorded normal
vital signs. (Id. at 3-4.) Petitioner reported that she had not experienced any loss of
consciousness, voiced no medical complaints, and declined to go to the hospital. (Id. at
4.) The Florida Highway Patrol subsequently arrived on scene at 5:35pm. (Ex. 20, p.
1.) The officer indicated that petitioner was not distracted at the time of the accident,
did not have obscured vision, and was “apparently normal” at the time of the accident.
(Id. at 2.) He cited petitioner for careless driving. (Id.) Petitioner testified that following
the accident she “felt fine” and “just wanted to go home.” (Tr. 16.) It wasn’t until she
went home that she “fell on the bed [and] that was it,” causing her to conclude the next
day that she should go to the hospital. (Tr. 17.) Petitioner could not recall her
interaction with Fire Rescue (Tr. 15-16); however, on cross-examination she
acknowledged that she would have been truthful in speaking with them (Tr. 51-52).
C. Post-accident hospital visit
When she first reported for triage at the emergency department the next day,
petitioner reported that she “felt disoriented while driving” and “snapped out of it when
[the] airbag deployed.” (Ex. 13, p. 22.) A handwritten intake form further records that
she had a “’black’ out before accident.” (Id. at 23.) A further history indicates that she
“got disoriented and doesn’t remember speeding across 2 lanes and hitting a car on the
other side” and further that she “couldn’t see.” (Id. at 14.) The initial clinical impression
at the emergency department was syncope and closed head injury. (Id. at 21.)
Petitioner was admitted for disorientation and possible syncope. (Id. at 33.) Petitioner
was first evaluated by Dr. Mukeshumar Patel, who assessed her with sudden loss of
vision with disorientation of unknown etiology. (Id. at 34.)
5This is only to note that Mr. Skarka did not confirm any loss of consciousness. To the extent petitioner
contends that she “woke up” when the airbag deployed (Tr. 11-12), the two accounts are not inherently in
conflict.
6
When petitioner reported for a neurology consultation with Dr. Rakesh P. Shah,
she reported that she “was just driving back to her home, was in the car, knew that she
was making a left turn, was just waiting for the traffic to just pass by, and then she
suddenly lost her control, could not focus, could not see, and everything kind of foggy,
slightly blacked out, and without any loss of consciousness. The patient just woke up
after she hit another car in the apartment and the patient was kind of surprised herself,
was giving all the answers appropriately to the state trooper . . .”6 (Ex. 13, p. 36
(emphasis added).) Dr. Shah felt petitioner’s description of not being able to see was
“questionable” and concluded there were “no signs of syncopal episode.” (Id. at 37.)
Importantly, although the emergency department histories also state that
“[patient] states hit head on roof of car” and that she suffered a “head injury” (Id. at 22-
23), petitioner subsequently acknowledged in testimony that she did not ever remember
hitting her head and that she was told by others, most notably her husband, as an after-
the-fact rationalization that she must have hit her head. (Tr. 17, 47-48, 61.) This was
the reason she ultimately sought care. (Tr. 17.) Additionally, Dr. Shah noted that
petitioner answered the state troopers questions “appropriately,” but petitioner also
testified that she was “dazed” and in “shock” as a result of the accident and, as noted
above, Mr. Skarka likewise observed petitioner to seem confused in the moments after
the accident. (Tr. 16, 65; Ex. 28, p. 1.) Petitioner further testified that Dr. Shah
observed her to be “not acting right,” contributing to the impression that she suffered a
concussion. (Tr. 18-19.) Asked to review and confirm the history recorded by Dr. Shah,
petitioner testified “I’m not sure,” but also indicated “I might have said something.” (Tr.
20.) Accordingly, it is very difficult to discern from the most contemporaneous medical
records what statements reflect reliable, independent recollections of what petitioner
experienced during her auto accident.
During the course of her one-day hospitalization, petitioner had various tests
conducted, including a chest x-ray, EEG, ultrasound, which all had presented normal
results. (Ex. 5, pp. 1-4.) Additionally, petitioner’s neck, head, brain, and spine CT
scans did not show any remarkable findings. (Id. at 7.) Petitioner was discharged from
Medical Center of Trinity on October 15, 2015. (Ex. 13, p. 38.) Petitioner’s discharge
diagnosis was “sudden loss of vision with disorientation, unknown etiology, resolved.”
(Ex. 5, p. 7.)
6 One could question the apparent inconsistency within this record – indicating no loss of consciousness
immediately followed by reference to having “woke up.” (Ex. 13, p. 36.) However, this is consistent with
the description elicited in the emergency department wherein petitioner described only disorientation
followed by “snap[ping] out of it.” (Ex. 13, p. 22.) During the hearing, petitioner similarly indicated that the
airbag “woke me up” in the context of indicating that this was the “next thing I can remember” in the
aftermath of having lost control of the vehicle. (Tr. 11-12.) It is also noteworthy that the record includes
the characterization of petitioner as “slightly blacked out,” further evidencing that Dr. Shah is attempting to
capture a history being provided by petitioner that indicates something less than a complete blackout.
(Ex. 13, p. 22.)
7
D. Subsequent medical history
Petitioner was not seen by any doctor again until December 10, 2015, when she
saw neurologist Indira Umamaheswaren, M.D. (Ex. 5, p. 21.) Petitioner’s description of
her alleged syncopal episode continued to evolve. Whereas she previously denied
losing consciousness and described being “slightly blacked out,” she described to Dr.
Umamahesawaren experiencing everything becoming “white.” (Id.) She was assessed
with post-concussion syndrome and episode of loss of awareness of unclear etiology,
with differential diagnosis being syncope versus seizures versus cardiac etiology. (Id. at
22.)
On January 14, 2016, petitioner returned to see Dr. Umamaheswaren for follow
up regarding her post-concussion syndrome. (Ex. 5, p. 26.) Petitioner still had mild
headaches and feelings of being off balance while walking. Petitioner was not feeling
herself and had difficulty focusing. (Id. at 27.) Dr. Umamaheswaren advised that
petitioner’s symptoms could take months to resolve. (Id. at 28.) Petitioner returned for
a follow up on June 30, 2016, complaining of similar symptoms as well as lack of
energy. (Id. at 30.)
Petitioner first saw Dr. Tedodulo Mationg on March 10, 2016 with complaints of
nausea, headache, sleep problems, and frequent urinary tract infections. (Ex. 11, p.
29.) Dr. Mationg advised petitioner to have a colonoscopy and encouraged her to follow
up with her psychiatrist. Dr. Mationg further assessed petitioner with generalized
anxiety disorder. (Id. at 30-32.)
On August 22, 2016, through referral from Dr. Mationg, petitioner saw Dr.
Krishna Ganti for left ear problems. (Ex. 9, p. 12.) Petitioner reported that she had a
head injury over a year ago, but that there was no loss of consciousness (“no LOC”).
She presented with several months of fullness, pain, and pressure feeling over her left
ear. (Id.) Dr. Ganti suspected Meniere’s disease or inflammatory labyrinthitis. (Id. at
13.)
Petitioner saw Dr. Ganti again on September 6, 2016 regarding her hearing loss.
(Ex. 11, pp. 86-87.) Petitioner again reported that she had a car accident last year,
where she was flustered and appeared confused, and although she could not provide
more details, petitioner recalled having a concussion. (Id. at 86.) Although exam
findings and test results suggested Meniere’s disease or inflammatory labyrinthitis, at
this visit, petitioner was diagnosed with sensorineural hearing loss and subjective
tinnitus. (Id. at 87.)
Petitioner called Dr. John Pirrello’s office on June 28, 2017, stating that she lost
her eyesight and fell. (Ex. 15, p. 157.) Petitioner stated that she was not dizzy at the
time of the fall and did not know how she fell but that she could not see. (Id.) Petitioner
was subsequently seen by Theresa R. Haffner, ARNP, for her fall on June 30, 2017.
(Id. at 159.) NP Haffner recorded that petitioner lost her footing and fell forward at a
department store, and further that petitioner denied any head trauma and loss of
consciousness. (Id.) Petitioner wanted to discuss her worsening anxiety. Although fall
8
precautions were discussed and there was a fall risk screening, no advanced care
planning was needed. (Id. at 160-161.) Additionally, on July 20, 2017, petitioner called
her PCP’s office again to add that when she fell, her vision went black and after a
moment she regained sight as if “someone turned the lights back on.” (Id. at 170.)
Petitioner also indicated that she had a panic attack earlier on the day of the fall that
may have set off her temporary blindness.7 (Ex. 15, p. 170.) Petitioner saw Dr. Pirrello
on July 20, 2017 regarding abdominal pain, unrelated to her fall. (Id. at 171.)
On October 22, 2019, petitioner reported to Dr. Shah that she was in a lot of
stress, had mental confusion, and some issues with short-term memory loss. (Ex. 31,
p. 6.) Dr. Shah ordered a brain MRI to look for any signs of memory loss or dementia.
Petitioner saw Dr. Shah again on December 2, 2019 to discuss her brain MRI results.
(Id. at 1.) Her MRI showed chronic periventricular white matter changes without acute
ischemic stroke. (Id.) Compared with petitioner’s August 28, 2016 MRI, there were
extensive bilateral white matter T2 and FLAIR sequence hyperintensities and bilateral
inflammation of her mastoids. (Id. at 3.) Petitioner was diagnosed with dementia, most
likely vascular dementia. (Id. at 1.)
IV. Expert Opinions
A. Petitioner’s Expert, Marcel Kinsbourne, M.D.
Dr. Kinsbourne explained that syncope results when there is a drop in blood
pressure and diminution of perfusion of the brain. (Ex. 23, p. 2.) He indicated that
“[a]mong the causes is emotional distress, associated with blood drawing or needle
puncture in [the] course of vaccination. An emotional reaction to the needle, the pinprick
or the association with blood can cause an exaggerated response of the vagus nerve,
reducing the blood pressure.” (Id.)
With regard to petitioner’s own presentation, he opined “Ms. Kidwell had an
unmistakable syncopal episode. Prominent among symptoms of syncope are feeling
funny (probably dizzy), being confused and having blurry and tunnel vision. She lost
control of her car. Her [primary care physician] had omitted the recommended 15
minutes of staying seated in the office after her vaccination.” (Id. at 1.) Dr. Kinsbourne
indicated that petitioner’s medical records do not reflect any cardiovascular cause for
her syncope nor any other syncopal episodes. (Id.) Dr. Kinsbourne did not address
petitioner’s post-concussion syndrome.
B. Respondent’s Expert, Peter Donofrio, M.D.
Dr. Donofrio similarly described the mechanism of syncope as relating to
insufficient blood flow to the brain, but stressed that it represents a form of transient loss
of consciousness. (Ex. A, p. 5.) He identified vasovagal syncope in particular as being
7 Petitioner’s daughter, who was with her at the time of the fall, submitted an affidavit in which she averred
that petitioner fell, but did not pass out. (Ex. 26.) The affidavit did not address whether petitioner
separately experienced any loss of vision as reflected in her reports to physicians.
9
reflex-mediated in response to prolonged standing or emotional distress. (Id.) Dr.
Donofrio explained that syncope has numerous causes in addition to the type of
emotional distress highlighted by Dr. Kinsbourne, including orthostatic hypotension from
dehydration or bleeding, adverse reactions to medication, dysautonomia, and can be
secondary to a number of cardiovascular conditions. (Id.)
Dr. Donofrio disagreed that petitioner’s October 13, 2015 “spell” constituted a
syncopal event. (Id.) In reaching this conclusion he relied in particular on the fact that
petitioner initially denied losing consciousness and also that her description of the event
has been inconsistent. (Id. at 5-6.) Dr. Donofrio also suggested that other causes for
petitioner’s spell are evidenced in her medical records. Additional spells occurring on
June 20, 2012, May 20, 2013, and July 20, 2017, as well as reports of “squares” in her
vision, flashing lights, and nausea, are consistent with migraines. (Id. at 6.) Petitioner
was also later diagnosed with Meniere’s Disease in October of 2016. (Ex. A, p. 6.)
Additionally, petitioner previously demonstrated bradycardia on August 23, 2015 and
June 11, 2012. (Id.) Dr. Donofrio opined that the October 13, 2015 spell is consistent
with bradycardia leading to loss of blood pressure and perfusion of blood to the brain.
(Id.) Dr. Donofrio did not address petitioner’s post-concussion syndrome.
V. Party Positions
A. Petitioner’s contentions
Petitioner contends that the record evidence is clear in demonstrating that
petitioner experienced an auto accident within one hour of her influenza vaccination and
that a causal presumption is therefore warranted under the Vaccine Injury Table. (ECF
No. 78, p. 1.) Petitioner asserts that, consistent with syncope, she became confused
and disoriented, which caused her to initially confuse the gas and brake pedals, and
later passed out as her vehicle crossed traffic and ultimately collided with a parked
vehicle. (Id. at 2.)
Petitioner contends that the subsequent medical records discussing petitioner’s
state at the time of the accident are “imprecise” and ultimately incorrect as far as any
reference to there having been no loss of consciousness. (Id. at 3.) Petitioner further
notes that the medical records contain no neurologic explanation for syncope. (Id.)
Petitioner also suggests that “[e]ven if the Special Master finds petitioner did not fully
lose consciousness, Petitioner was clearly confused. Dr. Kinsbourne supports the event
as a syncopal episode even without a total loss of consciousness.”8 (Id. at 4 (citing Ex.
23).)
Petitioner acknowledges that her testimony was affected by a failing memory, but
contends that “even with that disability, the facts that are relevant to this case came
8 For the reasons discussed above, this would be inconsistent with a Table Injury regardless of Dr.
Kinsbourne’s endorsement. According to the QAI, vasovagal syncope “means loss of consciousness
(fainting) and postural tone.” 42 CFR §100.3(c)(13). I will separately address whether Dr. Kinsbourne’s
opinion could support an alternative cause-in-fact claim.
10
through, again and again.” (Id. at 5.) Petitioner also asserts that her “version of events
is the only one that makes sense. A person who is conscious takes their foot off the
gas. They do not drive into a parking lot at 50 miles per hour and run into parked cars.
Syncope is the only explanation for what we know happened.” (ECF No. 78, p. 5.)
In response to respondent’s contentions, petitioner further stressed that there is
evidence in the contemporaneous medical records both that petitioner lost
consciousness and that she suffered syncope. (ECF No. 79, p. 2.) Petitioner also
stressed that she had no signs of dementia at the time of the accident, further
explaining “[a]nyone might miss the brake pedal and accidentally hit the gas. However,
everyone would take their foot off the pedal when they started accelerating instead of
slowing down. The exception would be if someone had lost the ability to control their
motor functions because they were suffering a syncopal event.” (Id. at 3.)
B. Respondent’s contentions
Regarding the Table claim alleged by petitioner, respondent first stressed that
petitioner has not established the time of her vaccination, leaving it impossible for her to
demonstrate that her alleged syncopal event occurred within one hour of vaccination.
(ECF No. 77-1, p. 19.) He additionally contended that petitioner’s medical records do
not substantiate a syncope diagnosis, stressing the evidence that suggests there was
no loss of consciousness. (Id. at 20.) To the extent petitioner’s testimony and
allegations contradict the medical records, respondent argues that petitioner’s failing
memory detracts from her credibility. (Id. at 21-22.)
Respondent argues that Dr. Kinsbourne’s report is not credible with respect to a
cause-in-fact claim because it relies on a diagnosis (syncope) that is not supported by
petitioner’s medical records. (Id. at 24.) Respondent also stresses that petitioner’s
treating physicians did not support vaccine-causation, noting that her primary care
physician opined that her accident was “[l]ikely not from flu vaccine.” (Id. at 24 (quoting
Ex. 4, pp. 69-70).) Respondent further argues that any cause-in-fact claim would suffer
the same limitation as her Table claim with respect to establishing the timing of the
alleged injury. (Id. at 24-25.)
Finally, respondent also argues that in either event petitioner “has ignored
potential alternative causes of her symptoms.” (ECF No. 77-1, p. 25.) Specifically,
respondent contends that petitioner’s overall medical history suggests the October 13,
2015 episode is more likely to have been caused by a migraine phenomenon, Meniere’s
disease, or sinus bradycardia. (Id. (citing Ex. 23, p. 1; Ex. A, p. 6).)
VI. Discussion
A. The weight afforded petitioner’s testimony
A critical threshold question presented in this case is how much weight to afford
petitioner’s testimony. Both parties acknowledge that petitioner’s testimony was
affected by failing memory. (ECF No. 78, p. 5; ECF No. 77-1, p. 21-22.) However, they
11
disagree with respect to the specific circumstances of her dementia at the time of the
hearing. While respondent stressed that petitioner was assessed as having dementia
two months prior to the hearing (ECF No. 77-1, n.3), petitioner replied that her dementia
was “mild, early onset” and she has never been deemed incompetent or otherwise
mentally unsound (ECF No. 79, p. 4).
The process for making determinations in Vaccine Program cases regarding
factual issues begins with consideration of the medical records. § 300aa-11(c)(2). The
special master is required to consider “all [ ] relevant medical and scientific evidence
contained in the record,” including “any diagnosis, conclusion, medical judgment, or
autopsy or coroner's report which is contained in the record regarding the nature,
causation, and aggravation of the petitioner's illness, disability, injury, condition, or
death,” as well as “the results of any diagnostic or evaluative test which are contained in
the record and the summaries and conclusions.” § 300aa-13(b)(1)(A). The special
master is then required to weigh the evidence presented, including contemporaneous
medical records and testimony. See Burns v. Sec'y of Health & Human Servs., 3 F.3d
415, 417 (Fed. Cir. 1993) (it is within the special master's discretion to determine
whether to afford greater weight to contemporaneous medical records than to other
evidence, such as oral testimony surrounding the events in question that was given at a
later date, provided that such a determination is evidenced by a rational determination).
Medical records that are created contemporaneously with the events they
describe are presumed to be accurate and “complete” (i.e., presenting all relevant
information on a patient's health problems). Cucuras v. Sec’y of Health & Human
Servs., 993 F.2d 1525, 1528 (Fed. Cir. 1993); Doe v. Sec'y of Health & Human Servs.,
95 Fed.Cl. 598, 608 (2010) ( “[g]iven the inconsistencies between petitioner's testimony
and his contemporaneous medical records, the special master's decision to rely on
petitioner's medical records was rational and consistent with applicable law”).
Accordingly, if the medical records are clear, consistent, and complete, then they should
be afforded substantial weight. Lowrie v. Sec'y of Health & Human Servs., No. 03–
1585V, 2005 WL 6117475, at *20 (Fed. Cl. Spec. Mstr. Dec. 12, 2005). Indeed,
contemporaneous medical records are generally found to be deserving of greater
evidentiary weight than oral testimony—especially where such testimony conflicts with
the record evidence. Cucuras, 993 F.2d at 1528; see also Murphy v. Sec'y of Health &
Human Servs., 23 Cl. Ct. 726, 733 (1991), aff'd, 968 F.2d 1226 (Fed. Cir.), cert. den'd,
Murphy v. Sullivan, 506 U.S. 974, 113 S.Ct. 463, 121 L.Ed.2d 371 (1992) (citing United
States v. United States Gypsum Co., 333 U.S. 364, 396, 68 S.Ct. 525, 92 L.Ed. 746
(1948) (“[i]t has generally been held that oral testimony which is in conflict with
contemporaneous documents is entitled to little evidentiary weight.”)).
However, there are situations in which compelling oral testimony may be more
persuasive than written records, such as where records are deemed to be incomplete or
inaccurate. Campbell v. Sec'y of Health & Human Servs., 69 Fed. Cl. 775, 779 (2006)
(“like any norm based upon common sense and experience, this rule should not be
treated as an absolute and must yield where the factual predicates for its application are
weak or lacking”); Lowrie, 2005 WL 6117475, at *19 (“[w]ritten records which are,
12
themselves, inconsistent, should be accorded less deference than those which are
internally consistent”) (quoting Murphy, 23 Cl. Ct. at 733). Ultimately, a determination
regarding a witness's credibility is often needed when determining the weight that such
testimony should be afforded. Andreu v. Sec’y of Health & Human Servs., 569 F.3d
1367, 1379 (Fed. Cir. 2009); Bradley v. Sec'y of Health & Human Servs., 991 F.2d
1570, 1575 (Fed. Cir. 1993). When witness testimony is offered to overcome the
presumption of accuracy afforded to contemporaneous medical records, such testimony
must be “consistent, clear, cogent, and compelling.” Sanchez v. Sec’y of Health &
Human Servs., No. 11-685V, 2013 WL 1880825, at *3 (Fed. Cl. Spec. Mstr. Apr. 10,
2013) (citing Blutstein v. Sec'y of Health & Human Servs., No. 90–2808V, 1998 WL
408611, at *5 (Fed. Cl. Spec. Mstr. June 30, 1998). In making a determination
regarding whether to afford greater weight to contemporaneous medical records or
other evidence, such as testimony at hearing, there must be evidence that this decision
was the result of a rational determination. Burns, 3 F.3d at 417.
During the hearing, petitioner repeatedly denied having a medical history
consistent with what had been recorded in her medical records relative to multiple
medical providers. (For example, compare Tr. 80 (denying panic attacks) and Ex. 15,
pp. 159, 170; Ex. 27, pp. 7-9, 50-51; compare Tr. 76-77 (denying referral to psychiatrist)
and Ex. 11, pp. 31-32, 38-39; compare Tr. 22-23 (denying migraines) and Ex. 12, pp.
92-95; compare Tr. 28-29 (denying Meniere’s disease) and Ex. 9, pp. 12-13; Ex. 11, pp.
88-93.) Petitioner did not provide any reason for the discrepancies or explanation of
why her medical records did not align with her recollections. However, she nonetheless
purported to offer testimony regarding the details of encounters she acknowledged
being unable to recall. (Tr. 17-18, 56, 62, 70-75.) Petitioner also offered some
contradictory testimony regarding her prior health. (Compare Tr. 21-22 (indicating
bloodwork is “always perfect”) and Tr. 23 (acknowledging taking cholesterol
medication).) A very notable example featured prominently in respondent’s cross-
examination. Petitioner testified clearly, and unprompted, on direct examination that
she had never had a prior influenza vaccination. (Tr. 8.) She confirmed the same on
cross-examination. (Tr. 37.) On further cross-examination, respondent presented
petitioner with multiple consent forms and administration records for prior influenza
vaccinations, which petitioner acknowledged signing. (Tr. 37-40.) Petitioner’s utter
surprise when presented these documents was obvious during the hearing and even
remains discernable from the resulting transcript. (Id.)
My observation of the quality of petitioner’s testimony regarding her own medical
history is that it is clearly not reliable enough to overcome the presumption of accuracy
typically allowed contemporaneous medical records. Accordingly, I do not credit any of
petitioner’s testimonial denials of relevant aspects of her medical history over what
appears in her contemporaneously recorded medical records.9 Petitioner’s dementia
diagnosis and her concession in her briefs that her memory was affected at the time of
9 Notably, however, as noted in Section III C, above, even the contemporaneous histories petitioner
provided after her accident are not entirely clear regarding what she could recall versus what she
rationalized as the cause of her condition.
13
the hearing may help to further explain how petitioner’s testimony came to be unreliable
with respect to her medical history, but the quality of the testimony is apparent
regardless of that explanation.
Importantly, however, this does not account for the whole of petitioner’s
testimony. Aspects of petitioner’s testimony that relay affirmative recollections rather
than negative recollections (i.e. denials) cannot easily be explained by mere memory
loss. Moreover, petitioner persuasively stressed in her briefs that, even faced with
advanced age and dementia, “a traumatic event like the car crash at issue is still
indelibly imprinted in her mind.” (ECF No. 79, p. 4.) In that regard, petitioner was very
clear in testifying as to the affect the accident had on her. She testified that the memory
of the accident caused her to experience ongoing fear that led her to stop driving. (Tr.
21, 67-68.) This is also supported by her reports to physicians. (E.g., Ex. 5, p. 21.)
Accordingly, petitioner’s specific affirmative recollections will be weighed against the
other record evidence on an individual basis.
B. Petitioner’s auto accident likely occurred within one hour of
vaccination
Respondent stresses that the exact time that petitioner was vaccinated is
unclear. (ECF No. 77-1, p. 19.) While this is true – the vaccination record does not
indicate the time of administration (Ex. 1) – there is sufficient circumstantial evidence to
conclude that it is more likely than not that petitioner’s alleged syncopal event (if it
occurred) happened within one hour of her influenza vaccination.
The fact that petitioner’s vaccine was administered during her primary care
appointment at Dr. Herndon’s office is well documented. (Ex. 1; Ex. 4, p. 68.) There is
no evidence that petitioner was seen by anyone in Dr. Herndon’s office prior to 3:43pm
when her vital signs were first recorded. (Ex. 4, p. 65.) Emergency dispatch and
accident report records confirm that petitioner’s subsequent auto accident was reported
between 4:32pm and 4:38pm, which is less than an hour after petitioner’s medical
appointment likely began based on the above-referenced time stamp.10 (Ex. 14, p. 1;
Ex. 20, p. 1.) Petitioner also stresses there is no evidence of record contradicting her
assertion that the accident occurred within one hour of vaccination. (ECF No. 79, p. 4.)
Accordingly, even without knowing the precise time of vaccination, there is
preponderant, albeit not definitive, evidence that petitioner’s auto accident (immediately
preceded by her alleged syncope) occurred within one hour of her vaccination.11
10Potentially consistent with this, petitioner believed her appointment was at 4:00pm or later and that her
vaccination occurred after she was seen by her doctor. (Tr. 6-7, 41-42.) This arguably provides further
evidence regarding the timing of petitioner’s vaccination; however, the time stamp(s) on the medical
record remain the best available evidence regarding the time she was actually seen. Notably, vital signs
are typically taken at the beginning of an appointment so they may be considered during the encounter.
11
The Vaccine Act instructs that the special master may find the time period for the first symptom or
manifestation of onset required for a Table Injury is satisfied “even though the occurrence of such
14
However, this does not necessarily mean that what petitioner experienced constituted
Table Injury of vasovagal syncope.
C. There is not preponderant evidence that petitioner lost
consciousness or suffered a Table Injury of vasovagal syncope
A difficult and fundamental issue in resolving this case is the fact that petitioner
was alone at the time of her alleged syncopal event, has acknowledged being unable to
remember key moments, and subsequently has not provided a consistent description of
what actually happened inside her vehicle at the time of the accident. The beginnings
of this inconsistency arise as early as the moments following the accident and it affects
the medical histories she provided to physicians following her accident. Because
petitioner bears the burden of establishing the factual circumstances of her claim (§
300aa–13(a)(1)(A)), these difficulties prevent any finding by preponderant evidence that
petitioner lost consciousness at or around the time of her accident. Accordingly, there
is not preponderant evidence that she suffered a Table Injury of vasovagal syncope.
As explained in greater detail in Section III B, above, petitioner’s
contemporaneous account to first responders was that she did not lose consciousness,
causing her to receive a traffic citation for careless driving. (Exs. 14, 20.) Moreover, the
only witness on the scene did not confirm any loss of consciousness. (Ex. 28.) As
reflected in Section III C, above, her subsequent reports to medical providers when
hospitalized the next day were inconsistent in reporting whether she experienced a loss
of consciousness. (Ex. 13, pp. 22, 36.) Additionally, the record as a whole reveals
even those contemporaneous accounts to be a mix of recollection and after-the-fact
rationalization.
To some extent this is understandable. If petitioner was, in fact, unconscious,
she could not be expected to recall her own unconsciousness. Nor does it seem
possible to meaningfully parse her later report of “loss of vision” or being “slightly
blacked out” coupled with an inability to recall from a true loss of consciousness.12 (Id.
at 22, 36.) However, these explanations still remain inconsistent with petitioner’s
specific denial of having lost consciousness, made both to first responders and to her
first post-accident neurologist, Dr. Shah, the latter of whom explicitly considered and
symptom or manifestation was not recorded or was incorrectly recorded as having occurred outside such
a period.” §300aa-13(b)(2).
12 During the hearing, I asked petitioner to compare what she experienced in her car on that day to
another seemingly similar incident, but this did not help to resolve the issue. Petitioner’s medical records
reflect that in June of 2017, she momentarily lost her vision while shopping and fell down. (Ex. 15, pp.
157-159.) As with the October 2015 episode, she denied loss of consciousness or dizziness. (Id.) In
describing this incident during testimony, petitioner confirmed that she was able to recall that “it went dark
and I knew I was going to fall.” (Tr. 80.) I asked petitioner to focus on the last moment she could recall
before the auto accident and compare it to what she experienced when she fell down. She indicated it
was “nothing like that, nothing.” (Tr. 81.) I specifically asked petitioner if she could recall losing her vision
after she saw the trees “whirring by.” She could not recall. (Id.)
15
rejected the possibility that petitioner had experienced a syncopal event.13 (Ex. 14, p. 4;
Ex. 5, pp. 7-8.) To deny a loss of consciousness is to recall remaining conscious.
Importantly, although she repeatedly disputed during the hearing any suggestion that
she did not lose consciousness, petitioner could not disclaim the reports contained in
either Dr. Shah’s or the first responders’ records. Upon review of this history contained
in Dr. Shah’s record, she indicated that she could not recall and “might have said
something.” (Tr. 20.) She also could not recall her interactions with the fire department
at the accident scene but vouched for her truthfulness to them. (Tr. 51-52.) Petitioner
again confirmed much later that she did not lose consciousness when she first saw Dr.
Ganti in August of 2016. (Ex. 9, p. 12.)
Moreover, petitioner’s hearing testimony confirms that she has a clear and
cogent recollection of losing control of her vehicle, including her specific recollection of
seeing trees pass by along the side of the road and of being afraid for her safety. (Tr.
10-12.) Additionally, contrary to her argument that unconsciousness is the only possible
explanation for the accident, petitioner also specifically confirmed in testimony that she
continued to depress the gas pedal “all the way” after losing control because she
mistakenly believed she was pressing the brake pedal and the brakes were failing. (Tr.
10-11, 20, 54.) This testimony is not consistent with a loss of consciousness. In her
earlier affidavit, petitioner had likewise not indicated any loss of consciousness. (Ex.
21, p. 1.)
Although petitioner testified that she could not recall what subsequently
happened in the final moments before impact, without more, and especially in light of
the above, this does not a fortiori suggest that she lacked consciousness due to
syncope. She reasonably noted that “it happened so fast.” (Tr. 54.) Petitioner
described the events as “all hell br[eaking] loose” and also explained that she was
“dazed” and in “shock” as a result of the accident. (Tr. 17, 56, 65.) Additionally, the
only eyewitness available was concerned petitioner may have had a concussion and,
indeed, she was later treated for post-concussion syndrome.14 (Ex. 28; Ex. 5, pp. 20-
23.) Petitioner also has a history of panic attacks. (Ex. 15, p. 170; Ex. 27, pp. 7-9.)
Even without suspecting her subsequently diagnosed dementia, these are factors that
could plausibly contribute to petitioner’s failure to recall the final moments of her
13 The fact that Dr. Shah discussed with petitioner whether she lost consciousness in the context of
assessing whether she experienced syncope is significant because petitioner urges that petitioner’s
motivation should be considered in assessing her medical records. (ECF No. 79, pp. 1-2.) Specifically,
petitioner argues that the first responder reports should be discounted because she denied losing
consciousness on the day of the accident in an effort to avoid being hospitalized. (Id.) In contrast, by the
time petitioner was seen by Dr. Shah she was already hospitalized and actively seeking medical
treatment.
14Given that petitioner clearly recalls initially losing control of the vehicle before later being unable to
recall subsequent events, this raises the question of whether a concussion and post-concussion
syndrome could instead explain the entirety of her presentation, including her alleged momentary loss of
consciousness and/or inability to remember the final moments of the accident. However, because this
would require additional expert opinion regarding the nature of concussions and their effects, I do not
reach that question.
16
accident that do not implicate any syncope-induced confusion or lack of consciousness.
Considering the record as a whole, petitioner’s lack of memory may be potentially
consistent with a loss of consciousness, but it does not in itself provide preponderant
evidence favoring petitioner’s assertion that a loss of consciousness did occur.
D. Petitioner has not met her burden of proof with respect to any
alternative cause-in-fact claim
Setting aside the question of whether petitioner lost consciousness as required
by the specific requirements of the Vaccine Injury Table, petitioner also asserts that Dr.
Kinsbourne’s opinion supports her contention that she suffered a syncopal event
regardless of whether she experienced a loss of consciousness. This raises the
separate question of whether petitioner has nonetheless proven a cause-in-fact claim.
There are several issues relative to Althen prong two, requiring a logical sequence of
cause and effect showing that petitioner’s vaccination did cause her injury, that prevent
petitioner from establishing any cause-in-fact claim by preponderant evidence.
First, petitioner is not persuasive in separating syncope from a loss of
consciousness. Dr. Kinsbourne and Dr. Donofrio both agree that syncope results from
a loss of blood perfusion in the brain that can be brought about by, among other things,
emotional stress. Dr. Kinsbourne’s further suggestion that a needle injection can cause
such stress appears to be sound and reliable insofar as the potential for syncope is
factored into the standard of care when administering the flu vaccine. (E.g., Ex. 10, p.
5.) This satisfies Althen prong one. Importantly, however, nothing on this record
supports petitioner’s suggestion that syncope occurs without a loss of consciousness.
This raises an Althen prong two issue given that there is not preponderant evidence that
petitioner lost consciousness.
Dr. Kinsbourne, though he highlighted dizziness, confusion, and blurry or tunnel
vision as “prominent” symptoms, did not explicitly opine that syncope occurs in the
absence of a loss of consciousness.15 (Ex. 23, p. 1.) Moreover, to the extent he opined
specifically that petitioner suffered syncope fitting the definition of a Table Injury of
vasovagal syncope, his opinion may be better characterized as inferring based on
overall presentation that a loss of consciousness likely did occur rather than opining that
syncope is itself anything other than a loss of consciousness. In any event, even if Dr.
Kinsbourne did opine that a loss of consciousness was not necessary to syncope, that
opinion would not be supported on this record. (E.g., Ex. 10, p. 5 (vaccine package
insert characterizing syncope as fainting that “may be accompanied” by transient
neurological signs such as visual disturbance); Ex. A, Tab 1, p. 1 (characterizing
syncope as transient loss of consciousness that “is often preceded by” symptoms such
as lightheadedness or blurred vision). Accordingly, in light of my above finding of fact,
Dr. Kinsbourne is not persuasive in opining that a syncope occurred. In contrast, Dr.
15Dr. Kinsbourne’s reference to tunnel vision would also seem to be inconsistent with petitioner’s
testimony that she observed trees passing by as she lost control. (Tr. 11, 13, 32, 46, 53-55, 64-65, 81.)
This testimony seems to suggest intact peripheral vision.
17
Donofrio is persuasive in explaining that petitioner’s October 13, 2015 spell is not
consistent with syncope. (Ex. A.)
Prior cases in this program have acknowledged the separate concept of
“presyncope” as constituting faintness or lightheadedness without any loss of
consciousness. See, e.g., Yalacki v. Sec'y of Health & Hum. Servs., No. 14-278V, 2019
WL 1061429, at n. 19 (Fed. Cl. Spec. Mstr. Jan. 31, 2019), mot. rev. denied, 146 Fed.
Cl. 80 (2019); Balasco v. Sec'y of Health & Hum. Servs., No. 17-215V, 2020 WL
1240917, at *18 (Fed. Cl. Feb. 14, 2020). One prior decision further characterized
presyncope as representing some unspecified degree of decreased consciousness.
Turkupolis v. Sec'y of Health & Hum. Servs., No. 10-351V, 2014 WL 2872215, at *10
(Fed. Cl. Spec. Mstr. May 30, 2014). Importantly, however, these prior cases
addressed a different medical context in which presyncope was discussed only as a
possible symptom of a broader presentation and not as a direct consequence of
vaccination. Here, Dr. Kinsbourne has not specifically opined that petitioner suffered
“presyncope.” He has not substantiated what constitutes a presyncope in general or
whether presyncope would necessarily be incapacitating. Nor has he discussed
whether he would opine, given petitioner’s overall medical history, that a presyncopal
episode would have the same causal relationship to vaccination in this case that he
proposed with regard to a syncopal episode. (For example, in Turkopolis the special
master explained that certain types of migraine may include presyncope sensations.
Id.)
Respondent is also persuasive in contending that petitioner’s medical records do
not contain preponderant evidence from petitioner’s treating physicians that petitioner
suffered a syncopal event. Although that possibility was considered during petitioner’s
initial emergency department triage (Ex. 13, p. 21), she was subsequently seen by
neurologist Dr. Shah who explicitly concluded there was no evidence of syncope (Id. at
37). Ultimately, syncope was not a part of petitioner’s discharge diagnosis. (Ex. 5, pp.
7-8.) Later, Dr. Umamahewswaran included syncope only as among a differential
diagnosis also including seizure and cardiac event. (Id. at 21.) Moreover, petitioner has
a history of panic attacks which have been suspected as the cause of a separate
episode similarly described as involving a visual blackout without loss of consciousness.
(Ex. 15, p. 170; Ex. 27, pp. 7-9.)
Dr. Umamahewswaran’s record is confusing in that she attached a diagnosis of
“syncope” to the encounter, but in her assessment indicated that the episode of loss of
awareness was of unclear etiology. (Id.) Her later records drop the encounter diagnosis
of syncope while maintaining the assessment of a loss of awareness of unclear etiology.
(Id. at 32.) On the whole, Dr. Umamahewswaran’s treatment records reflect greater
focus on petitioner’s subsequent post-concussion syndrome than on the initial cause of
her accident. Dr. Shah’s encounter record appears to offer the most extensive
consideration of whether the history provided by petitioner represented a syncopal
event and that assessment was based on a more contemporaneous recollection than
was available to Dr. Umamahewswaran. (Ex. 13, pp. 36-37.) Of course, none of
petitioner’s treating physicians directly observed the episode in question.
18
Finally, to the extent petitioner may have otherwise experienced a “spell” on
October 13, 2015 represented only by confusion and/or a loss of vision, petitioner has
not articulated any explanation linking such a spell to her vaccination absent the
presence of syncope. Respondent is also persuasive in suggesting that petitioner’s
overall medical history is potentially consistent with other explanations for such a spell.
Although a definitive etiology is not captured by her medical records, petitioner has had
spell-like episodes on a number of occasions. (See e.g., Ex. 12, p. 156 (flashing lights);
Ex. 12, pp. 92-95 (saw squares); Ex. 15, p. 99 (dizziness and nausea); Ex. 15, pp. 157-
59, 170 (losing vision and falling).)
Dr. Kinsbourne indicated that “[m]edical records do not reflect any cardiovascular
disease process that might be conducive to syncope, and Ms. Kidwell’s medical records
offer no evidence of any previous syncopal episodes or any further syncopal episodes
since then.” (Ex. 23, p. 1.) However, this assertion does not address alternative causes
of petitioner’s presentation suggested by her medical history that do not constitute
syncopal events, such as the panic attacks, migraines, and Meniere’s disease
referenced by Dr. Donofrio. (Ex. A, pp. 6-7.) Nor is this assertion persuasive in light of
Dr. Donofrio’s observation of prior suspected syncopal events and bradycardia. (Id.)
E. There is not preponderant evidence that petitioner’s alleged
syncopal episode caused her accident and post-accident symptoms
Regardless of theory – Table or cause-in-fact injury – petitioner must also
establish that her injuries satisfy the Vaccine Act’s severity requirement. § 300aa-
11(c)(1)(D). In relevant part the Vaccine Act requires petitioner to demonstrate that the
residual effects of her injury persisted for at least six months.16 Id. Because syncope is
a transient and generally harmless condition, it necessarily follows that petitioner must
also somehow causally link her longer-term treatment for headaches and unsteady
walking (characterized as post-concussion syndrome) to her syncope in order to
demonstrate a compensable injury.
Petitioner has neither alleged nor demonstrated that her longer-term symptoms
were a direct sequela of her syncope, but rather contends that the persistent injuries
she suffered were the result of trauma she experienced in the ensuing auto accident.
Petitioner suggests, in effect, a causal chain in which her vaccination caused her
syncope which caused her accident which caused her post-concussion syndrome.
However, petitioner’s above-discussed testimony that she lost control of the vehicle due
16 Under the Vaccine Act, petitioner must have either:
(i) suffered the residual effects or complications of such illness, disability, injury, or
condition for more than 6 months after the administration of the vaccine, or (ii) died from
the administration of the vaccine, or (iii) suffered such illness, disability, injury or condition
from the vaccine which resulted in inpatient hospitalization and surgical intervention.

to pedal misapplication contradicts that framing of events and therefore raises an
additional issue of proximate causation. In all events, petitioner must prove that her
vaccination was a proximate cause of her injury or injuries. Shyface v. Sec’y of Health
& Human Servs., 165 F.3d 1344, 1352 (Fed. Cir. 1999) (adopting the Second
Restatement of Torts with regard to proximate causation in the Vaccine Program and
determining a vaccine must be both a “but for” cause and a “substantial contributing
factor”); Stone v. Sec’y of Health & Human Servs., 676 F.3d 1373, 1381 (Fed. Cir.
2012) (examining the Second Restatement of Torts with regard to superseding causes,
but determining that such analysis is not necessary where the special master found no
casual role for the vaccine). Even under a Table Injury approach, the causal
presumption afforded petitioner would extend only as far as the vaccine’s role in
causing her alleged syncope, which is the specific injury included on the Table.
The core of petitioner’s claim is her assertion that her “version of events is the
only one that makes sense. A person who is conscious takes their foot off the gas.
They do not drive into a parking lot at 50 miles per hour and run into parked cars.
Syncope is the only explanation for what we know happened.” (ECF No. 78, p. 5.) But
this is belied by petitioner’s own testimony. As noted above, petitioner was clear and
cogent in testifying that the cause of the accident was her own misapplication of the gas
pedal when she intended to apply the brakes. (Tr. 20, 81.) She further testified that she
kept her foot on the gas after losing control because she continued to believe it was the
brake pedal. (Tr. 10-11, 46.) The eyewitness at the scene further confirmed that
petitioner still had her foot on the gas after her vehicle came to a stop. (Ex. 28.) It is
only the details occurring after she had already lost control of her vehicle that petitioner
cannot recall. Contrary to syncope being the “only explanation” of her accident,
petitioner credibly described the cause of her accident as pedal misapplication.
Petitioner’s broader suggestion that syncopal confusion or a loss of
consciousness are the only reasonable explanations for this type of accident is not
correct. Accidents due to sudden unintended acceleration are a well-known
phenomenon and litigation involving that type of accident has explored many potential
causes including design and mechanical defects as well as driver error. See, e.g.,
Bullock v. Volkswagen Group of America, Inc., 107 F.Supp.3d 1305, 1317 (M.D. Ga.
2015) (noting an expert’s “opinion is directly relevant and would be helpful to the jury on
the issue of causation—whether driver error, instead of design defect, caused the
wreck.”); Buck v. Ford Motor Co., 810 F. Supp. 2d 815, 838 (N.D. Ohio 2011) (“Sero
concluded that the cause of the sudden rapid acceleration could only be one of two
explanations: ‘either the driver mistakenly put ‘pedal to the metal’ or the cruise control
system electronically failed.’ Sero then proceeded to rule out driver error as a potential
cause. To make this determination, Sero relied on: 1) witness testimony; 2) brake pedal
wear; and 3) driver habit. Sero's specific causation opinion must be excluded because
he has not reliably ruled out driver error.”) (internal citation omitted); Jarvis v. Ford
Motor Co., 283 F.3d 33, 46 (2d Cir. 2002) (“Although Ford argued that the accident was
caused instead by driver error, this theory would have been rejected if the jury had
believed Jarvis's testimony that she had her feet on the brake and not on the
accelerator, as Ford claimed.”).
20
Petitioner does not bear the burden of eliminating alternative independent causes
of her injury, but “is certainly permitted to use evidence eliminating other potential
causes to help carry the burden on causation and may find it necessary to do so when
the other evidence on causation is insufficient to make out a prima facie case.” See
Walther v. Sec’y of Health & Human Servs., 485 F.3d 1146, 1151 (Fed. Cir. 2007).
Here, to the extent petitioner herself indicates that she is relying in part on the lack of
any alternative explanation, it is not self-evidently true as petitioner suggests that a
person who is conscious and of sound mind would not be involved in an accident
involving sudden unintended acceleration. As petitioner correctly acknowledged in her
reply brief, “[a]nyone might miss the brake pedal and accidentally hit the gas.” (ECF
No. 79, p. 3.)
Accordingly, petitioner’s auto accident is more likely than not explained by her
admitted pedal misapplication and she has therefore not established by preponderant
evidence that her post-accident symptoms were causally related to her vaccination.17
Thus, her alleged injury also does not meet the Vaccine Act’s severity requirement.
VII. Conclusion
Petitioner has my sympathy for the pain and suffering she endured due to her
traumatic accident, and I do not doubt her sincerity in bringing this claim. However, for
all the reasons discussed above, after weighing the evidence of record within the
context of this program, I cannot find by preponderant evidence that petitioner suffered
any injury caused by her October 13, 2015 flu vaccination. Therefore, this case is
dismissed.18
IT IS SO ORDERED.

17Because I have concluded that there is not preponderant evidence that petitioner’s accident was
caused by her alleged syncope, I do not reach the further questions of whether her post-accident
condition did represent a post-concussion syndrome, whether her symptoms could otherwise be linked
accident trauma, or whether her symptoms persisted for at least six months. As noted above, petitioner
does not actually recall hitting her head.
18In the absence of a timely-filed motion for review of this Decision, the Clerk of the Court shall enter
judgment accordingly.
