I FACTUAL BACKGROUND

A. Relevant Medical History

Petitioner, Michaela Waterman, is an eighteen year-old female who received a series of
three Gardasil vaccinations on December 29, 2011, February 29, 2012, and July 11, 2012, to
protect her against the HPV virus. Petition at 1. Petitioner thereafter suffered from a number of
conditions, the most troublesome of which are daily painful and itchy hives, injuries which
Petitioner alleges were caused by the Gardasil vaccinations.

Petitioner received her first Gardasil immunization on December 29, 2011. See Pet. Ex.
1 at 19-22. She was described as alert and cooperative and was receiving counseling without any

Petitioner was a minor at the time of the filing, so her mother filed the action on her behalf.
Once she reached the age of majority, the caption was amended on January 5, 2016 to name
Michaela Waterman as the only petitioner. Order, ECF No. 55, 56.

Exhibit List filed February 24, 2014.

current medication for her depression. Id. She was otherwise healthy. Id. Within “a month or
so” after administration of the first vaccination, Petitioner developed a red bubbly rash with a
burning sensation on her abdomen and back. Tr. 17; Pet. Ex. 1 at 23-24. A couple of days later,
when the rash “had gotten a lot worse,” Petitioner sought out medical attention from her primary
care provider (“PCP”), Dr. Laurie Huntress, at Turner Health Center, on January 28, 2012. Tr.
18, Pet. Ex. 1 at 23-24. She was prescribed Valtrex (Valacyclorvir HCl) for treatment of “likely”
shingles. Pet. Ex. 1 at 24.

Petitioner was given the second Gardasil injection on February 29, 2012. Pet. Ex. 1 at
26. Approximately three months later, on June 5, 2012, Petitioner again visited Turner Health
Center, this time complaining of “getting hives on a regular basis,” with occurrences “a couple of
times per week.” Id. at 27. Antihistamine treatment was recommended, and Petitioner was
referred to an allergist. Id. at 28.

Petitioner saw the allergist, Dr. Andrew B. Carey, on June 28, 2012. Pet. Ex. 4. Dr.
Carey noted that Petitioner’s hives had persisted for four months, and that the hives were more
prominent two weeks after the second Gardasil vaccination was administered. Pet. Ex. 4 at 2-4.
“Cutaneous testing by the prick method to relevant allergens including foods, latex, dust mite,
animal dander, mold, and pollen was negative.” Id. at 3. Dr. Carey’s impression remarks
included “[c]onsider a role for Gardisil (sic) although there is no available testing for this.” Id.
Dr. Carey diagnosed Petitioner with chronic urticaria5 and placed her on antihistamine therapy.
Id. at 3. “A panel of hive related labs was ordered including a CU index and thyroid antibodies.”
Id. at 4. Dr. Carey reviewed the risks and benefits of Gardasil injections with Petitioner and her
mother and noted that “mother indicates that the patient does clearly need this” and that “[i]n her
case, her benefits likely outweigh the risks.” Id.

Petitioner received her third Gardasil immunization on July 11, 2012. Pet. Ex. 1 at 30.
Dr. Carey saw her (accompanied by her mother) the following day and reported that the hives
were still occurring, but were “70% improved” with regular antihistamine use. Pet. Ex. 4 at 5.

Petitioner visited her primary care physician at Turner Health Center on August 15, 2012
with complaints of skin rashes that were described as “erythematous macular patches with
visible collarettes and some central clearing,” with unknown etiology. Pet. Ex. 1 at 32.
Petitioner returned to Turner Health Center a week later, on August 21, 2012, with a recurring
sore throat and pruritic rash on her hands, but no febrile presentation. Id. at 35. Petitioner was
referred to another allergist on September 10, 2012, after her mother called Petitioner’s PCP to
express her discontent with the allergist and her concern about the injuries being an immune

Urticaria is “vascular reaction in the upper dermis, usually transient, consisting of localized
edema caused by dilatation and increased capillary permeability with wheals.” Dorland’s
Illustrated Medical Dictionary (32d. 2012) (hereinafter “Dorland’s”).

system issue. Pet. Ex. 1 at 40. On September 25, 2012, Petitioner was admitted to the
emergency room complaining of a rash, where the attending physician noted that “this was likely
an allergenic versus a rheumatoid issue” and that “the parent is professing frustration with the
care that so far her child has received.” Pet. Ex. 6 at 2. During this visit, a routine serology-
immunology test was performed for detecting autoimmune disease. Pet. Ex. 6 at 6. The tests
came back negative with no mention of visible joint inflammation. Id.

On September 27 and 28, 2012, Petitioner saw the second allergist, Dr. Michael Lunn,
whose physical examination revealed chronic urticaria “recalcitrant to multiple antihistamines.”
Pet. Ex. 5 at 4. Dr. Lunn noted the lab work ordered by Dr. Carey, including a complete blood
count with differential, sedimentation rate, and liver function tests, all of which were normal. See
Pet. Ex. 5 at 1. The history set forth by Dr. Lunn was consistent with that noted by other
providers, including shingles one month after the first vaccine, diffuse hives approximately one
month after the second, and chronic urticaria, bruising, joint pains in her hands, feet and knees
without visible synovial swelling, fatigue, and headaches, beginning approximately three to four
weeks after the final vaccination. Id. at 1- 4. Dr. Lunn diagnosed Petitioner with “Urticaria:
Likely idiopathic,” and stated that “[a]lthough there is a temporal relationship between the
injection and the onset of her current symptoms, it was discussed extensively that there is no way
to say with certainty that the vaccine itself was the culprit for her urticaria.” Id. at 3-4.

Because Petitioner’s physician questioned the possibility of rheumatoid arthritis,
Petitioner also saw a rheumatologist, Dr. Lee Kendall, on October 2, 2012. See generally Pet.
Ex. 3. Dr. Kendall stated that it was unlikely that Petitioner’s condition was inflammatory
arthritis. Id. at 3. He also noted that “the fact that . . .her symptoms occurred about a month
after getting the Gardisil (sic) would argue against this being an immediate hypersensitivity type
reaction” but that “[w]hether the reaction is related to the Gardisil (sic) is not entirely clear.” Id.

Finally, on October 15, 2012, Petitioner saw a third allergist, Dr. Ari Fried, at Boston
Children’s Hospital, who noted that the previous skin biopsy taken by Dr. Carey was consistent
with urticaria that did not have features of vasculitis. Pet. Ex. 2 at 2. Dr. Fried noted that
“[s]teroid bursts have led to complete resolution of all her skin and other symptoms. However,
when discontinued symptoms recur.” Id. at 1. He stated that the idiopathic urticaria seen with
Petitioner was a “condition for which the causes are still not well known in most patients.” Id.
Dr. Fried ruled out hypersensitivity reaction to the Gardasil vaccine but noted that, given the
time course and presentation of Petitioner’s condition, a relationship between the vaccination and
a possible elicited immune response “cannot be ruled out with certainty.” Id. at 3. Dr. Fried
recommended long-term antihistamines, as well as counseling to help Petitioner address the
emotional distress her condition had caused her. Id.

 B. Resolution of Disputed Factual Issue – Onset Following Second Vaccination

Respondent challenged the timing of onset of Petitioner’s hives after the second Gardasil
injection, asserting that the passage of approximately two months from when the hives allegedly
started to when Petitioner sought treatment for them was “distinctly unusual” and cast doubt on
the timing of onset. See, e.g., Resp. Ex. A at 5. Petitioner’s testimony at hearing addressed the
discrepancy. She stated that when the hives first started in early April, she did not tell her
mother at first, because she had a trip planned to New York with her grandparents to celebrate
her April 3rd birthday. Tr. 21-24. She did eventually tell her mother, the day before she left for
New York, and her mother told her to “just wait it out.” Tr. 24-25. While in New York, she
tried several different treatments, including calamine lotion and gel and Benadryl, which did not
help. Id. When she returned from New York, she discussed the issue with her mother again.
Her mother told her “that when she was younger. . .she had some hives and it was just from
whatever and that I should just wait it out because it’s just hives, it’s not like I’m sick or
anything, you know? And she didn’t have too much money at the time, so we kind of waited it
out and it got worse.” Tr. 26. Finally, Petitioner testified that her mother was preoccupied with
caring for a friend dying from cervical cancer, so Petitioner tried not to “bug” her and just live
with it, although her mother did take her lotions and makeup away from her after noticing the
hives, apparently thinking the lotions and make-up might be the source of the irritation. Tr. 28-
29. Finally, Petitioner testified, “I was at my school and I had a bunch of hives during my math
class and some people had been making comments about it, and I said, mom, I need to go to the
doctor’s and get this fixed,” tr. 29, but the doctor was booked, “[s]o I think it was like a week
after I had told her that we went.” Tr. 30. This account was essentially confirmed by
Petitioner’s mother during her hearing testimony, including that the witness had a number of
other responsibilities for patients and a dying friend and an ill family member, and that Petitioner
is “kind of a tough kid, you know. . . and it was just she kind of dealt with it.” Tr. 80-84.

The undersigned finds this testimony credible. In addition it is consistent with the
contemporaneous medical records, including those of Dr. Carey, Pet. Ex. 4 at 2-4, and Dr. Lunn,
Pet. Ex. 5 at 4. Therefore, the undersigned FINDS that the onset of hives after the second
Gardasil vaccination dated February 29, 2012, occurred no later than the end of March or the
first week of April 2012.

II EXPERT QUALIFICATIONS

III LEGAL STANDARD

To receive compensation under the Program, Petitioner must prove either 1) that she
suffered a “Table Injury” — i.e., an injury falling within the Vaccine Injury Table6 —
corresponding to one of her vaccinations, or 2) that Petitioner suffered an injury that was actually
caused by a vaccine. See 42 U.S.C.A. § 300aa-13(a)(1)(A); see also § 300aa-11(c)(1).
Petitioner must show that the vaccine was “‘not only a but-for cause of the injury but also a
substantial factor in bringing about the injury.’” Moberly v. Sec’y of Health & Human Servs.,
592 F.3d 1315, 1321-22 (Fed. Cir. 2010) (quoting Shyface v. Sec’y of Health & Human Servs.,
165 F.3d 1344, 1352-53 (Fed. Cir. 1999)). Petitioner has not claimed a Table Injury, and an
examination of the record has not revealed any possible Table Injury.

6
The Vaccine Injury Table “lists the vaccines covered under the Act; describes each vaccine's
compensable, adverse side effects; and indicates how soon after vaccination those side effects
should first manifest themselves. Claimants who show that a listed injury first manifested itself
at the appropriate time are prima facie entitled to compensation.” Bruesewitz v. Wyeth, LLC, 562
U.S. 223, 228 (2011) (citing 42 U.S.C.A. §§ 300aa-11(c) (1), 300aa-13(a)(1)(A)).
6
 Absent a Table Injury, Petitioner must satisfy all prongs of the test established by the
Federal Circuit in Althen v. Secretary of the Department of Health and Human Services. 418
F.3d 1274, 1278-79 (Fed. Cir. 2005). The Althen test requires the petitioners to set forth: “(1) a
medical theory causally connecting the vaccination and the injury (“Althen Prong One”); (2) a
logical sequence of cause and effect showing that the vaccination was the reason for the injury
(“Althen Prong Two”); and (3) a showing of a proximate temporal relationship between
vaccination and injury (“Althen Prong Three”).” Id. To establish entitlement to compensation
under the Program, a petitioner is required to establish each of the three prongs of Althen by a
preponderance of the evidence. Id.

The preponderance of the evidence standard has been interpreted to mean that the
petitioner must show that the fact is more likely than not. Moberly, 592 F.3d at 1322 n. 2 (Fed.
Cir. 2010). Proof of medical certainty is not required. Bunting v. Sec’y of Health & Human
Servs., 931 F.2d 867, 873 (Fed. Cir. 1991). “[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.” Althen, 418 F.3d at 1280.

In determining whether Petitioner is entitled to compensation, the undersigned will
consider all relevant, material contained in the record. 42 U.S.C.A. § 300aa-13(b)(1). That
material can include circumstantial evidence. Capizzano v. Sec’y of Health & Human Servs.,
440 F.3d 1317, 1325 (Fed. Cir. 2006). As the finder of fact, the undersigned is “entitled—
indeed, expected—to make determinations as to the reliability of the evidence presented…and, if
appropriate, as to the credibility of the persons presenting that evidence.” Moberly, 592 F.3d at
1326. The Vaccine Act was created to award compensation to vaccine-injured persons “quickly,
easily, and with certainty and generosity.” Graves v. Sec’y of Health & Human Servs., 109 Fed.
Cl. 579, 595 (2013) (quoting H.R. Rep. No. 99-908 at 3). Therefore, “close calls regarding
causation are resolved in favor of injured” petitioners. Althen, 418 F.3d at 1280; see also
Shyface v. Sec’y of Health & Human Servs., 165 F.3d 1344, 1352-53 (Fed. Cir. 1999).

If Petitioner satisfies all three prongs of Althen by a preponderance of the evidence, she
establishes a prima facie case. Walther v. Sec’y of Health & Human Servs., 485 F.3d 1146,
1149-51 (Fed. Cir. 2007). After Petitioner has established a prima facie case, the burden shifts to
Respondent to demonstrate, also by a preponderance of the evidence, that the injury was actually
caused by factors unrelated to the administration of the vaccine. Walther, 485 F.3d at 1151; 42
U.S.C.A. § 300aa–13(a)(1)(B). Accordingly, “[i]f the evidence is seen in equipoise, then the
government has failed in its burden of persuasion and compensation must be awarded.” Knudsen
v. Sec’y of Health & Human Servs., 35 F.3d 543, 550 (Fed. Cir. 1994).

To satisfy the first prong of the Althen test, Petitioner must provide “a medical theory
causally connecting the vaccination and the injury.” Althen, 418 F.3d at 1278 (quoting Grant v.

7
Sec’y of Health & Human Servs., 956 F.2d 1144, 1148 (Fed. Cir. 1992)). Petitioner’s theory
must show that it is more likely than not that the vaccine she received “can” cause the type of
injury Petitioner alleges the vaccine caused. Pafford v. Sec’y of Health & Human Servs., 451
F.3d 1352, 1355-57 (Fed. Cir. 2006).

The medical theory set forth by the Petitioner must be “legally probable, not medically or
scientifically certain.” Knudsen, 35 F.3d at 548-49 (citations omitted). However, the theory
cannot be baseless or completely speculative; it must be informed by “sound and reliable medical
or scientific explanation.” Id. at 548 (citations omitted); see also Veryzer v. Sec’y of Health &
Human Servs., 98 Fed. Cl. 214, 223 (2011) (noting that under 42 U.S.C.A. § 300aa-13(b)(1) and
Vaccine Rule 8(b)(1), special masters must consider only evidence that is both “relevant” and
“reliable”). When a petitioner proffers a medical opinion to support her theory, the basis for the
opinion and the reliability of that basis must be considered in determining how much weight to
afford the offered opinion. See Broekelschen v. Sec’y of Health & Human Servs., 618 F.3d 1339,
1347 (Fed. Cir. 2010) (“The special master’s decision often times is based on the credibility of
the experts and the relative persuasiveness of their competing theories.”)(citations omitted);
Perreira v. Sec’y of Health & Human Servs., 33 F.3d 1375, 1377 n. 6 (Fed. Cir. 1994) (“An
expert opinion is no better than the soundness of the reasons supporting it”) (citing Fehrs v.
United States, 620 F.2d 255, 265 (Ct. Cl. 1980)).

To satisfy the second prong of the Althen test, Petitioner must establish “’a logical
sequence of cause and effect showing that the vaccination was the reason for the injury.’” Althen,
418 F.3d at 1278 (citations omitted). That is, Petitioner must show, by preponderant evidence,
that the vaccination Petitioner received did cause the injuries she alleges they caused. Capizzano
v. Sec’y of Health & Human Servs., 440 F.3d 1317, 1326 (Fed. Cir. 2006). Petitioner may satisfy
her burden by presenting circumstantial evidence and reliable medical opinions; she is not
required to offer “epidemiologic studies, rechallenge, the presence of pathological markers or
genetic disposition, or general acceptance in the scientific or medical communities to establish a
logical sequence of cause and effect.” Id. at 1325.To satisfy the third prong of Althen, petitioners
must produce preponderant evidence of “a proximate temporal relationship between vaccination
and injury.” Althen, 418 F.3d at 1278. This prong helps to establish the connection between the
causal theory of Prong One and the more fact-based cause and effect arguments of Prong Two by
demonstrating “that the onset of symptoms occurred within a timeframe from which, given the
medical understanding of the disorder’s etiology, it is medically acceptable to infer causation-in-
fact.” de Bazan v. Sec’y of Health & Human Servs., 539 F.3d 1347, 1352 (Fed. Cir. 2008).
Petitioner may meet her timing burden by showing: (1) when the condition for which she seeks
compensation first appeared after vaccination, and (2) whether the period of symptom onset is
“medically acceptable to infer causation.” Shapiro v. Sec’y of Health & Human Servs., No. 99-
552V, 2011 WL 1897650, at *13 (Fed. Cl. Spec. Mstr. Apr. 27, 2011)(citation omitted), aff’d in
relevant part and vacated on other grounds, 101 Fed. Cl. 532, 536 (2011).

 IV ANALYSIS

“Proof of a medical theory explaining how a vaccine could cause an injury is analytically
distinct from proof that a vaccine actually did cause the injury.” Nussman v. Sec’y of Health &
Human Servs., 83 Fed. Cl. 111, 121 (July 21, 2008). However, evidence used to satisfy one
prong of Althen may be used to satisfy Althen’s other prongs, as well. Capizzano v. Sec’y of
Health & Human Servs., 440 F.3d 1317, 1326 (Fed. Cir. 2006).

Both experts agreed that chronic urticaria is very often idiopathic, that is, its cause is
unknown. Pet. Ex. 21 at 1; Tr. 174. Petitioner conceded that there are also no studies or articles
directly linking the Gardasil vaccine with chronic urticaria, although there are VAERS7 reports
of urticaria, see, e.g. Pet. Ex. 11,8 and pruritic9 rashes are listed on the Gardasil package insert as
a possible side effect. See Ct. Ex. 110) However, Dr. Axelrod argued, through presentation of
several articles, that chronic urticaria has been demonstrably linked to the ingestion or injection
of other drugs and vaccines.11 Pet. Ex. 8 at 2. Dr. Axelrod also presented the Lawley article

VAERS (“Vaccine Adverse Events Reporting System”) is a database created by the FDA and
the Centers for Disease Control and Prevention to receive reports about adverse events which
may be associated with vaccines. See Vaccine Adverse Event Reporting System, available at
https://vaers.hhs.gov/about/index. See also Nance v. Sec’y of Health & Human Servs., No. 06-
0730V, 2010 WL 3291896, at *9 (Fed. Cl. Spec. Mstr. July 30, 2010) (discussing that VAERS is
a surveillance system that accepts “voluntarily submitted” reports of events from manufacturers,
health care workers and patients, and that the experiences reported therein are unsolicited and
reflect a “concern of a possible relationship to vaccination”).

concerning serum sickness caused by vaccination with horse antithymocyte globulin,12 as
support for his theory that immune complexes can be induced by vaccines, that immune
complexes can cause autoimmune disease symptoms consistent with chronic urticarial, and that
that is what happened to Petitioner. Pet. Ex. 8 at 2-3; Tr. 148 (“Given what happened to her after
the third injection, she may very well have developed a form of serum sickness, you know. . .that
could very well have been an immune complex reaction.”)

Petitioner’s primary causation argument, however, was based on the concept of
challenge-rechallenge. “A rechallenge event occurs when a patient who had an adverse reaction
to a vaccine suffers worsened symptoms after an additional injection of the vaccine.” Capizzano,
440 F.3d at 1322. See also Nussman, 83 Fed. Cl. At 120 (“‘challenge-rechallenge happens when
a person (1) is exposed to one antigen, (2) reacts to that antigen in a particular way, (3) is given
the same antigen again, and (4) reacts to that antigen similarly.’ (citation omitted) Typically, the
second reaction is faster and more severe.”) Challenge-rechallenge is an accepted scientific
principle in Dr. Axelrod’s field of expertise. Tr. 152; see also tr.189 (Dr. Josephs).

Dr. Axelrod testified, and the medical records showed, that the degree of Petitioner’s
reaction escalated after each consecutive dose of the vaccine: it “occurred maybe a little bit
sooner and it was more aggressive.” Tr. 156. Further, he argued, there was no other “potential
insult to cause it.” Id.; see also Pet. Ex. 4 at 3 (testing to “relevant allergens. . .was negative”).
Both Dr. Lunn and Dr. Fried acknowledged the temporal relationship between the vaccinations
and the onset of Petitioner’s urticaria. Pet. Ex. 5 at 3-4; Pet. Ex. 2 at 3. This testimony,
Petitioner argued, shows that the Gardasil vaccines did cause her urticarial, as required by Althen
prong two. Petitioner also argued that, under the challenge-rechallenge paradigm, evidence that
shows that the vaccine did cause the injury, by implication also proves that the vaccine can cause
the injury, as required by Althen prong one. Petitioner’s Prehearing Submissions at 6.

 Respondent, through Dr. Josephs, questioned all of the articles Dr. Axelrod relied upon as
inapposite. Resp. Ex. A at 3-4; tr. 190-92. Respondent pointed out that Petitioner did not suffer
from serum sickness, Tr. 190, nor was she vaccinated with horse serum, or any of the vaccines
noted in the articles cited by Dr. Axelrod. Resp. Ex. A at 3-4; tr. 190-92. Respondent also
emphasized that the rash from which Petitioner suffered after her first HPV vaccine was
diagnosed and treated as shingles arising from a previous chickenpox infection, and therefore it
could not serve as the first event in a challenge-rechallenge sequence. Resp. Ex. A at 3; tr. 182-
184. Finally, Respondent challenged the time of the onset of Petitioner’s symptoms after the
second vaccine, an issue which has been resolved earlier in this Ruling.

From the undersigned’s perspective, this is a classic case of challenge-rechallenge. The
undersigned understands that the rash Petitioner experienced after the first HPV vaccine was
diagnosed as shingles. However, as Petitioner testified:

“The nurse – well, the nurse practitioner or the first person to come in the room
told me that I was only – I think it was like – she said that being that young, she
didn’t think it was shingles. And then the doctor came in and said – and then
looked at it and said, the only reason I wouldn’t think it was shingles is because
it’s not scaly, but I think it’s basically shingles. She kind of was looking at it and
pressing her hands along the side to see if it was along the same nerve and said,
it’s likely shingles, I would think that’s what it is.”

Tr. 19. In light of what came later this does not appear to be a definitive diagnosis, but a
diagnosis of first impression, as the most logical explanation of the problem at the time. No
testing was done to confirm the Zoster diagnosis. The undersigned’s review of the medical
records did not disclose that any treating physician went back to that first rash to reexamine its
genesis in light of Petitioner’s subsequent development of hives, and ultimately of chronic
urticaria.13 And in every other way, the development of Petitioner’s condition “fit[s] within the
challenge-rechallenge paradigm.” Nussman v. Sec’y of Health & Human Servs., 83 Fed. Cl. 111,
120 (July 21, 2008). See also Capizzano v. Sec’y of Health & Human Servs., 440 F.3d 1317,
1322 (Fed. Cir. 2006). Temporally, the “shingles” rash developed three weeks to a month after
the first vaccine, Pet. Ex. 1 at 23-24; the worsening hives and welts approximately one month

13
See, e.g., Pet. Ex. 4 at 1, wherein Dr. Carey noted that Petitioner had shingles after the first
vaccination, and that that “would be a different immune mechanism than hives,” but did not
question whether, in light of the further disease development experienced by Petitioner post-
vaccination, the shingles may have been a misdiagnosis of the first rash; Pet. Ex. 5 at 1, wherein
Dr. Lunn noted the first vaccination and “approximately one month later she developed a Zoster
infection of her abdomen.” While Dr. Lunn noted that Petitioner’s Zoster was treated with
antivirals “although it was uncertain whether the injection itself was the culprit for the Zoster
infection,” he did not question the nature of the rash as being other than Zoster.
11
after the second vaccine, see infra, at 4-5; and the third, most virulent, chronic urticaria, and the
joint pain, approximately three to four weeks after the final vaccine. Tr. 36-37. This is
internally consistent with the challenge-rechallenge paradigm, and also fits within the timeframe
that Dr. Axelrod testified was appropriate for the development of the underlying immunological
process he theorized is causing Petitioner’s condition. The condition also worsened with each
additional dose of the vaccine: each time the basic reaction started as a rash; after each of the
second and third rechallenge events, the rash became worse – more itchy, more painful, more
extensive. Tr. 36-38, 152, 156.

Even if the “shingles” was in fact shingles, and related to the first vaccination only by
coincidence, the undersigned would still find the challenge-rechallenge theory persuasive here.
The hives that arose three to four weeks after the second vaccination were “70% resolved” with
use of antihistamines as noted by Dr. Carey when he saw Petitioner the day after the
administration of the third vaccination, Pet. Ex. 4 at 5; three to four weeks later, the urticaria was
back, with a vengeance, and was recalcitrant to antihistamines. Pet. Ex. 5 at 4.

Although the undersigned does not have “evidence of ‘rechallenge’ in other injectees,” as
the special master did in Capizzano, 440 F.3d at 1322, the undersigned nevertheless concludes
that the evidence cited above constitutes “’such strong proof of causality that it is unnecessary to
determine the mechanism of cause—it is understood to be occurring,’” id. (citations omitted),
which satisfies the first prong of Althen.

“Proof of a medical theory explaining how a vaccine could cause an injury is analytically
distinct from proof that a vaccine actually did cause the injury.” Nussman v. Sec’y of Health &
Human Servs., 83 Fed. Cl. 111, 121 (July 21, 2008). However, evidence used to satisfy one
prong of Althen may be used to satisfy Althen’s other prongs, as well. Capizzano v. Sec’y of
Health & Human Servs., 440 F.3d 1317, 1326 (Fed. Cir. 2006). As noted above, the challenge-
rechallenge evidence presented by Petitioner also satisfies the second, logical cause and effect
prong of Althen, and temporally, the evidence fits with the theory of causation set forth by
Petitioner and with the challenge-rechallenge paradigm, and therefore also satisfies prong three
of Althen.

12
 VI CONCLUSION

For the reasons set forth above, the undersigned finds that Petitioner has shown by
medical records and competent medical opinion that her alleged medical condition was “more
likely than not” vaccine-caused, and that she is entitled to compensation. This case is now ready
to proceed in damages.

IT IS SO ORDERED.
