    OPINION AND ORDER
    Petitioner Scott Germaine seeks relief under the National Childhood Vaccine
    Injury Compensation Program, 42 U.S.C. § 300aa-10 to 34, on behalf of his grandson
    C.G., who experienced intussusception after receiving the third dose of a rotavirus
    vaccine.1 The Special Master denied the petition based on a finding that Mr.
    Germaine “has not established a persuasive medical theory connecting the third dose
    of the [rotavirus] vaccine with intussusception[.]” Special Master’s Decision (“SMD”)
    at 1 (ECF 62). That conclusion was not arbitrary or capricious, and is therefore
    SUSTAINED.
    To obtain compensation under the National Childhood Vaccine Injury
    Compensation Program, a petitioner must prove that a vaccine caused an injury.
    Althen v. Sec’y of Health & Human Servs., 
    418 F.3d 1274
    , 1278 (Fed. Cir. 2005). There
    are two ways to show causation: (1) through “a statutorily-prescribed presumption of
    causation upon a showing that the injury falls under the Vaccine Injury Table (‘Table
    injury’),” 
    id.
     (citing 42 U.S.C. § 300aa-14(a)), or (2) by proof of causation in fact “where
    the complained-of injury is not listed in the Vaccine Injury Table (‘off-Table injury’),”
    
    This Opinion was issued under seal on June 29, 2021. The parties were directed to propose redactions
    by July 13, 2021. No proposed redactions were submitted. The Court hereby releases publicly the
    Opinion and Order of June 29 in full.
    1 This Court has jurisdiction. See 42 U.S.C. §§ 300aa-11(c), 300aa-16(a). Mr. Germaine timely moved
    for review. See 42 U.S.C. § 300aa-12(e)(1).
    id. (citing 42 U.S.C. §§ 300aa-13(a)(1), 300aa-11(c)(1)(C)(ii)(I)). For off-Table injuries,
    causation in fact has three elements: “(1) a medical theory causally connecting the
    vaccination and the injury; (2) a logical sequence of cause and effect showing that the
    vaccination was the reason for the injury; and (3) a showing of a proximate temporal
    relationship between vaccination and injury.” Id.2 The sole question presented by the
    motion for review — and the only issue discussed by the Special Master — is whether
    Mr. Germaine satisfied the first of those elements.
    Intussusception between 1 and 21 days after a child’s first or second dose of a
    rotavirus vaccine is a “Table injury” where causation is presumed. 
    42 C.F.R. § 100.3
    (a)(XI) (vaccine table). But intussusception after the third dose is not. See 
    42 C.F.R. § 100.3
    (c)(4)(ii)(A) (“For purposes of paragraph (a) of this section, the following
    shall not be considered to be a Table intussusception: … Onset that occurs with or
    after the third dose of a vaccine containing rotavirus[.]”); see also National Vaccine
    Injury Compensation Program: Addition of Intussusception as Injury for Rotavirus
    Vaccines to the Vaccine Injury Table, 
    80 Fed. Reg. 35848
    , 35849 (June 23, 2015) (“The
    definition for presumption of vaccine causation only applies to the first and second
    dose of vaccine, and excludes intussusception occurring with or after the third dose.
    The third dose of rotavirus vaccines lacks sufficient evidence showing risk.”). Plaintiff
    must therefore prove causation in fact by preponderance of the evidence. See, e.g.,
    Althen, 
    418 F.3d at 1278
    .
    One way to show causation in fact is by establishing a “probable” biological
    mechanism for how the third dose of the rotavirus caused C.G.’s intussusception.
    Knudsen, 35 F.3d at 548–49. Mr. Germaine argues that intussusception could be
    caused by an “inflammatory response” to the rotavirus vaccine, Pet.’s Mot. for Rev. at
    5 (ECF 64), but the Special Master found that Mr. Germaine “has not carried his
    burden of proof based on the biological mechanism alone,” SMD at 8, a factual
    conclusion that should be upheld unless arbitrary or capricious. Munn v. Sec’y of Dep’t
    of Health & Hum. Servs., 
    970 F.2d 863
    , 870 n.10 (Fed. Cir. 1992); 42 U.S.C. § 300aa-
    12(e)(2)(B).
    The Special Master did not err. Beyond the generic reference to
    “inflammation,” little additional explanation appears in the Motion for Review or in
    the record before the Special Master. Without more detail, Mr. Germaine’s theory is
    not specific to the third dose of the rotavirus vaccine, and possibly not even to
    rotavirus vaccines as opposed to other vaccines. Nor is there any evidence that C.G.
    personally experienced inflammation that caused intussusception. See Knudsen, 35
    F.3d at 549. Mr. Germaine’s proposed mechanism thus cannot be a “probable” one.
    Id. at 548–49. It is only a hypothesis, a theoretical possibility. Although proof of
    2The government can rebut proof of causation by showing, “also by a preponderance of evidence, that
    the injury was in fact caused by factors unrelated to the vaccine.” Althen, 
    418 F.3d at 1278
     (quoting
    Knudsen v. Sec’y of Health & Human Servs., 
    35 F.3d 543
    , 547 (Fed. Cir. 1994)); see 42 U.S.C § 300aa-
    13(a)(1)(B).
    -2-
    causation does not “require identification and proof of specific biological
    mechanisms,” id. at 549, “a ‘plausible’ or ‘possible’ causal theory” is not enough, see
    Boatmon v. Sec’y of Health & Hum. Servs., 
    941 F.3d 1351
    , 1360 (Fed. Cir. 2019); see
    also Broekelschen v. Sec’y of Health & Hum. Servs., 
    618 F.3d 1339
    , 1345 (Fed. Cir.
    2010) (“[A] petitioner must provide a reputable medical or scientific explanation that
    pertains specifically to the petitioner’s case[.]”).
    Causation can also be shown by epidemiological evidence, i.e., by connecting
    medical literature about vaccine complications to a patient’s clinical record. Knudsen,
    
    35 F.3d at 549
     (explaining that “causation can be found in vaccine cases based on
    epidemiological evidence and the clinical picture regarding the particular child
    without detailed medical and scientific exposition on the biological mechanisms”). Mr.
    Germaine identified several studies purportedly showing a risk of intussusception
    after rotavirus vaccines. The Special Master discussed several of those studies, but
    concluded that none of them showed an association between the third dose of a
    rotavirus vaccine and intussusception. SMD at 11. That conclusion, likewise, must be
    upheld unless arbitrary or capricious. 42 U.S.C. § 300aa-12(e)(2)(B).
    Mr. Germaine claims the Special Master misinterpreted two studies.3 First, he
    proposes a different reading of Haber, et al., Intussusception After Rotavirus Vaccines
    Reported to US VAERS, 2006-2012, 131 Pediatrics 1042 (2013) (ECF 21). Mr.
    Germaine claims the Special Master overlooked Haber’s finding that “out of the 584
    confirmed cases of intussusception after [the rotavirus vaccine with a three-dose
    protocol], 29% (169 reports) were reported after dose 3.” Pet.’s Mot. for Rev. at 5.
    That argument makes little sense. If instances of intussusception were equally
    distributed across a three-dose vaccine, one would expect each dose to be associated
    with one-third of the intussusception cases. The fact that the third dose of the
    rotavirus vaccine is associated with slightly less than a third of the reported
    intussusception cases — especially without any statistical analysis — does not
    advance Mr. Germaine’s argument that Haber found “an increased risk of
    intussusception after the third dose[.]” Id.
    3 Any objections to the Special Master’s analysis of other studies are forfeited. See RCFC App. B, Rule
    24(b)(1) (requiring that motions for review of special master decisions must “fully and specifically state
    and support each objection” to the special master’s opinion); Yalacki v. Sec’y of Health & Hum. Servs.,
    
    146 Fed. Cl. 80
    , 92 n.5 (2019). Although I need not reach the issue, the weight of the remaining
    evidence would likely support the Special Master’s conclusion concerning causation even if Mr.
    Germaine’s objections were meritorious. See Hines v. Sec’y of Dep’t of Health & Hum. Servs., 
    940 F.2d 1518
    , 1526 (Fed. Cir. 1991) (“[E]ven if it was error, it was harmless because, as explained below, the
    special master’s decision was based on a number of factors and [petitioner] has not shown that reliance
    on the judicially noticed incubation period derived from the textbook was likely critical to the result.”);
    Doe/11 ex rel. Child/Doe/11 v. Sec’y of Dep’t of Health & Hum. Servs., 
    87 Fed. Cl. 1
    , 12 (2009) (“Even
    removing consideration of the skewed study and the Special Master’s extrapolation of [an infant’s]
    length, substantial evidence supports the Special Master’s conclusion that Petitioners failed to prove
    a prima facie case[.]”), aff”d sub nom. Doe v. Sec’y of Health & Hum. Servs., 
    601 F.3d 1349
     (Fed. Cir.
    2010).
    -3-
    More importantly, Mr. Germaine ignores Haber’s analysis of the raw numbers.
    Haber calculated the “excess risk” of intussusception associated with rotavirus
    vaccinations. Haber at 1044. Excess risk is a method of describing how a given risk
    factor affects the likelihood of death or disease compared with the background rate.
    Excess risk is derived from the related concept of “relative risk,” which is “[t]he ratio
    of the risk of disease or death among people exposed to an agent to the risk among
    the unexposed.” Fed. Jud. Ctr., Reference Manual on Scientific Evidence 627 (3d Ed.
    2011). “A relative risk of 1 indicates no association between association and disease.”
    
    Id.
     Excess risk is equal to relative risk minus 1.0, such that a positive number means
    a positive association between the risk factor and a given outcome, and a negative
    number means a negative relationship. Haber found that while the first and second
    doses were associated with a modestly positive excess risk (0.74 and 0.21 per 100,000,
    respectively), the third dose was associated with a negative excess risk (-0.16 per
    100,000), i.e., a reduction in the risk of intussusception. Haber at 1046, 1047.
    That excess risk figure, moreover, has to be taken with its statistical context.
    Haber found that the excess risk associated with the third dose of the rotavirus
    vaccine had a “confidence interval” of –0.38 to 0.27. 
    Id.
     A “confidence interval” is ‘[a]
    range of values … within which the true value is likely to fall[.]” Reference Manual
    on Scientific Evidence 621. A confidence interval that straddles a relative risk of 1.0
    (that is, an excess risk of 0.0) is “statistically insignificant,” see 
    id.,
     meaning that it is
    statistically indistinguishable from no change in risk. Haber’s data, properly
    understood, do not show that the third dose of a rotavirus vaccine has any statistically
    significant association with rates of intussusception. Haber therefore contradicts Mr.
    Germaine’s argument that the study found “an increased risk of intussusception after
    the third dose[.]” Pet.’s Mot. for Rev. at 5.
    Second, Mr. Germaine emphasizes that Koch, et al., Risk of Intussusception
    After Rotavirus Vaccination, 114 Deutsches Ärzteblatt Int’l 255 (2017) (ECF 21),
    found the “relative risk” of intussusception after the third dose was 1.14, “which
    demonstrates an increased relative risk of intussusception after the third dose[.]”
    Pet.’s Mot. for Rev. at 6. Mr. Germaine is correct that a relative risk greater than 1.0
    refers to an increased risk of an outcome, see Reference Manual on Scientific Evidence
    627, but once more he overlooks the confidence interval: 0.75 to 1.74. Koch at 255,
    259. The small increased relative risk, in other words, was statistically insignificant
    — indistinguishable from no increased risk at all. That is why Koch concluded —
    rightly, from a statistical perspective — that there is no increased risk of
    intussusception after the third dose of a rotavirus vaccine. Id. at 260. The Special
    Master, in turn, did not err in relying on that conclusion.

    CONCLUSION
    For the foregoing reasons, the motion for review is DENIED and the decision
    of the Special Master is SUSTAINED.
    The Clerk is directed to enter judgment accordingly.
    IT IS SO ORDERED.
