Opinion:
Opinion for the court filed by Circuit Judge PROST. Dissenting opinion filed by Circuit Judge NEWMAN.
PROST, Circuit Judge.
This case, brought under the National Childhood Vaccine Injury Act of 1986, 42 U.S.C. § 300aa-l to -34, as amended (the "Vaccine Act"), presents the question whether petitioner Cynthia LaLonde, on behalf of her son M.L., has proven by a preponderance of the evidence that M.L.'s diphtheria-tetanus-acellular pertussis ("DTaP") vaccination caused a focal brain injury. The special master found that although M.L.'s DTaP vaccination likely caused his initial anaphylactic reaction, Ms. LaLonde failed to establish under any reliable medical theory that M.L.'s anaphylaxis caused a focal brain injury. See La Londe v. Sec'y of Health & Human Servs., No. 06-435V, 2012 WL 5351164 (Fed.Cl.Spec.Mstr. Sept. 28, 2012). After a careful consideration of the record, the U.S. Court of Federal Claims upheld that finding. See La Londe v. Sec'y of Health & Human Servs., 110 Fed.Cl. 184 (2013). We affirm.
I. Background
The relevant facts are primarily those found by the special master in his detailed September 28, 2012 decision. See La Londe, 2012 WL 5351164, at *3-6. M.L. was born on September 24, 2003. At his fifteen-month well-child visit, his pediatrician noted that M.L. was walking and generally developing normally but did not "want to talk." On April 14, 2005, M.L. received several immunizations, including the DTaP vaccination. About five hours later, M.L. allegedly began experiencing an abnormally high fever and some swelling. The next day M.L. was admitted to the hospital with a diagnosis of "vaccine adverse reaction with secondary fever, an-giodema, and anaphylactoid reaction." J.A. 20. He was discharged on April 16, 2005. However, the following morning M.L.'s mother called an ambulance because M.L. was exhibiting signs of hypothermia and seizure-like episodes.
In the weeks and months following the administration of the DTaP vaccination, M.L.'s vocabulary allegedly decreased, worrying his parents and his doctors. An MRI of M.L.'s brain with and without contrast was normal, revealing a deep bilateral middle ear infection but no brain damage. Nonetheless, M.L. continued to exhibit several "seizure-like" activities, but after a few months he was weaned off anti-epileptic medication. After observing M.L.'s developmental delays and repetitive behaviors, a pediatric neurologist placed M.L. in the autism spectrum disorder category.
II. Procedural History
Ms. LaLonde filed a petition under the Vaccine Act on June 1, 2006, seeking compensation for M.L.'s alleged injuries. The case was assigned to a special master, who heard expert testimony from Dr. Marcel Kinsbourne for Ms. LaLonde. Dr. Kinsb-ourne testified that M.L. experienced a two-phase anaphylactic reaction that included a delayed second state. He pointed to medical literature that supports the existence of late-phase anaphylactic reactions and offered three possible mechanisms of injury that have been shown in medical literature to result from an anaphylactic reaction. However, Dr. Kinsbourne was unable to point to anywhere in the literature that describes the sequence of events that are presented in. this case. Dr. Kinsbourne also admitted that he lacked any reliable medical evidence supporting the notion that anaphylactic shock can cause focal brain injuries.
After reviewing the evidence in the case, the special master saw what he called a "major gap" in Ms. LaLonde's ease. La Londe, 2012 WL 5351164, at *1. He alerted Ms. LaLonde to this fact and allowed her to submit new evidence, updated medical records, and a revised expert report. Id. at *2. Nonetheless, after re-reviewing the entire record, the special master found two decisive defects in Ms. LaLonde's case: (1) Dr. Kinsbourne's opinions were based on information provided by Ms. LaLonde and not on medical information found in the record; and (2) the record indicated — and all experts agreed — that M.L.'s initial reaction to the immunizations resolved, and Dr. Kinsbourne's theory that there was a secondary, delayed anaphylactic reaction was unsupported by the record. Id. at *3.
On review, the Court of Federal Claims concluded that the special master abused his discretion by discrediting Dr. Kinsb-ourne's opinions that were based on statements made by Ms. LaLonde, even if some of her statements were in conflict with the medical records. La Londe, 110 Fed.Cl. at 204. Nonetheless, the Court of Federal Claims concluded that this abuse of discretion was "harmless." Id. It explained that the special master "quite properly re quired [Ms. LaLonde] to carry her burden to bring forward a reliable medical or scientific explanation," and she failed to do so. Id. at 201. Her expert, Dr. Kinsb-ourne, testified that he had never seen an anaphylactic reaction lead to a focal brain injury, he did not find any support for a link in the medical literature, and he had an incomplete understanding of how the reaction could evolve into a focal brain injury. Id.
We have jurisdiction to review the final judgment of the Court of Federal Claims under 42 U.S.C. § 300aa-12(f).
III. The VaCoine Act
In 1986, Congress passed the Vaccine Act to establish a program administered by the Secretary of Health and Human Services to increase the safety and availability of vaccines. See 42 U.S.C. § 300aa-1; Terran v. See'y of Health & Human Servs., 195 F.3d 1302, 1307 (Fed. Cir.1999). The Vaccine Act created the National Vaccine Injury Compensation Program, through which claimants could petition to receive compensation for vaccine-related injuries or death. See 42 U.S.C. § 300aa-10(a).
To receive compensation, a claimant must show, by a preponderance of the evidence, that the vaccinated person received a covered vaccine and either: (1) suffered an injury, condition, or a significant aggravation of a preexisting injury or condition listed on the Table within the requisite time frame, in which case causation is presumed (a "Table injury"); or (2) suffered an injury or condition or suffered the significant aggravation of a pre-exist-ing injury or condition not on the Table, in which case causation must be proven (a "non-Table injury")- See 42 U.S.C. § 300aa-11(c)(1)(C), 300aa-14; 42 C.F.R. § 100.3 (2011). To prove actual causation in a non-Table injury case, the petitioner must
show by preponderant evidence that the vaccination brought about [the] injury by providing: (1) a medical theory causally connecting the vaccination and the injury; (2) a logical sequence of cause and effect showing that the vaccination was the reason for the injury; and (3) a showing of a proximate temporal relationship between the vaccination and the injury.
Moberly ex rel. Moberly v. See'y of Health & Human Servs., 592 F.3d 1315, 1322 (Fed.Cir.2010) (quoting Althen v. See'y of Health & Human Servs., 418 F.3d 1274, 1278 (Fed.Cir.2005)). If the petitioner satisfies this burden, she is "entitled to recover unless the [government] shows, 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)) (alteration in original). The petitioner is not required to prove the case to a level of scientific certainty. Rather, the burden of showing something by a preponderance of the evidence, the most common standard in the civil law, simply requires 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, 592 F.3d at 1322 n. 2 (quoting Concrete Pipe & Prods, of Cal, Inc. v. Constr. Laborers Pension Trust for S. Cal., 508 U.S. 602, 622, 113 S.Ct. 2264, 124 L.Ed.2d 539 (1993)).
IV. STANDARD OF REVIEW
In Vaccine Act cases, we review a ruling by the Court of Federal Claims de novo, applying the same standard that it applies in reviewing the decision of the special master. Moberly, 592 F.3d at 1321 (Fed.Cir.2010) (citing Lampe v. Sec'y of Health & Human Sews., 219 F.3d 1357, 1360 (Fed.Cir.2000)). We review factual findings under the arbitrary and capricious standard, and we review legal rulings to determine whether they are "not in accordance with law." Id. (citing Munn v. Sec'y of Health & Human Sews., 970 F.2d 863, 870 n. 10 (Fed.Cir.1992)).
V. Discussion
On appeal, Ms. LaLonde argues that the special master made a legal error when he denied her claim for compensation. Relying on Knudsen v. Secretary of Health and Human Sewices, 35 F.3d 543 (Fed.Cir. 1994), she claims that the special master used an incorrect legal standard when he required Ms. LaLonde to prove the mechanism through which the initial anaphylactic reaction caused M.L. to later suffer focal brain injuries. She argues that although Dr. Kinsbourne had proposed three potential mechanisms, the special master discredited him due to his failure to specify which caused M.L.'s injury.
Additionally, Ms. LaLonde acknowledges that under our case law, a temporal relationship alone between a vaccination and injury would not logically support a causal relationship. Moberly, 592 F.3d at 1323. But she argues that "[tjhere is a very significant difference between inferring causation from a proximate temporal relationship between an anaphylactic reaction and an injury [which is what she requests that we do], and inferring causation from a proximate temporal relationship between a vaccination and an injury," which the law states is not enough to receive relief under the Vaccine Act. Pet'r's Reply Br. 10 (emphasis added). Ms. LaLonde claims that such a temporal association is a logical sequence of cause and effect; she asserts that the proximate temporal association between an anaphy-lactic reaction and a dramatic regression in speech skills suggests that the anaphylactic reaction caused the regression in speech skills.
Finally, Ms. LaLonde reminds the court that the purpose of the Vaccine Act's preponderance of the evidence 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. Ms. LaLonde also requests a remand and a new hearing so that she may present new evidence that has come to light in the six years since this case began.
We have considered all of Ms. LaLonde's arguments, and while we are certainly sympathetic to her and her son, M.L., we nonetheless conclude that Ms. LaLonde has failed to meet her burden to receive her requested relief. As Ms. La-Londe correctly states in her opening brief, "to require identification and proof of a specific biologic mechanism [in Vaccine Act cases] would be inconsistent with the purpose and nature of the vaccine compensation program." Pet'r's Br. 18 (quoting Knudsen, 35 F.3d at 549). However, in the past we have made clear that simply identifying a "plausible" theory of causation is insufficient for a petitioner to meet her burden of proof. Moberly, 592 F.3d at 1322. Instead, the statutory standard of preponderance of the evidence requires a petitioner to demonstrate that the vaccine more likely than not caused the condition alleged. See id. ("[P]roof of a 'plausible' or 'possible' causal link . is not the statutory standard."); see also 42 U.S.C. § 300aa-13(a)(l).
Ms. LaLonde's expert, Dr. Kinsb-ourne, hypothesized that M.L. suffered a two-stage anaphylactic reaction — the first phase occurring before his hospital admission on April 15, 2005 and the second phase occurring when his mother called for an ambulance on April 17, 2005. Although Dr. Kinsbourne submitted medical literature describing a two-phase anaphylactic reaction, this literature does not support his testimony that M.L. had a reaction similar to the type the literature described with regard to either the timing of a two-phase event or the type of injury Ms. LaLonde alleges. Moreover, Dr. Kinsb-ourne acknowledged that he had never before seen the sequence he posited as having occurred here, and that it was "beyond rare." J.A. 91. And when asked to provide support for his theory that an anaphylactic reaction could cause a focal brain injury, Dr. Kinsbourne testified he did not know whether his theory was generally accepted or even discussed in the medical community. J.A. 90-91. He further testified that he had never seen an anaphylactic reaction lead to a focal brain injury, could not find support for it in the medical literature, and possessed an incomplete understanding of how the injury could evolve into a focal brain injury. Id.
Thus, contrary to Ms. LaLonde's argument, the special master did not require Dr. Kinsbourne to provide proof of his proposed mechanism, but instead merely required that he support his testimony with a reputable or scientific explanation that pertained specifically to M.L.'s case. See Hibbard v. Sec'y of Health & Human Sews., 698 F.3d 1355, 1365 (Fed. Cir.2012) (requiring petitioner to show both the medical plausibility of her theory of causation and that the injury was consistent with that theory). And the special master did not err in finding that Dr. Kinsbourne failed to do so.
In Moberly, we concluded that "the only . evidence in the record providing any support for [petitioner's] theory of causation was the testimony of Dr. Kinsbourne, which the special master had found to be 'contradictory and confusing' and 'shockingly poor.' " 592 F.3d at 1321. Similarly, in that case, Dr. Kinsbourne testified that his proposed mechanism had never been tested in any peer-reviewed study. Id. at 1324. In affirming the finding that Dr. Kinsbourne's testimony was insufficient, we noted that he "undercut his own position by conceding not only that [his proposed theory] had never been tested, but also that there was no evidence suggesting that it applied to [the petitioner's] case." Id. at 1325. Likewise, here Dr. Kinsb-ourne has proposed three mechanisms, but none are supported in any peer-reviewed study. And there is no evidence beyond Dr. Kinsbourne's testimony suggesting that any of the three proffered mechanisms applied to M.L.'s case.
Furthermore, as the finder of fact, the special master was responsible for assessing the reliability of Dr. Kinsbourne's testimony by looking for reliable medical or scientific support. See Moberly, 592 F.3d at 1324-25. In doing so, the special master was "entitled — indeed, expected— to make determinations as to the reliability of the evidence presented to [him] and, if appropriate, as to the credibility of the persons presenting the evidence." Id. at 1326. Regarding Dr. Kinsbourne's testimony, the special master stated that he found it "necessary to address the credibility of petitioner's expert," and noted that the "testimony in this case was as poor as any the undersigned has experienced in twenty years." La Londe, 2012 WL 5351164, at *17.
Additionally, it was not the government's burden to provide an alternative explanation. See, e.g., Althen, 418 F.3d at 1278 (stating that only after the petitioner satisfies her burden by preponderant evidence does the burden shift to the government to show that the injury was in fact caused by factors unrelated to the vaccine); 42 U.S.C. § 300aa-13. Nonetheless, the government's expert witness, Dr. John MacDonald, not only contradicted Dr. Kinsbourne's testimony by stating that he did not believe that M.L. had a focal brain injury as a result of an anaphylactic reaction but also pointed to the evidence in the record supporting his theory that M.L.'s speech delay was caused by a deep bilateral middle ear infection. J.A. 145, 277, 297.
In Vaccine Act cases, petitioners must proffer trustworthy testimony from experts who can find support for their theories in medical literature in order to show causation under the preponderance of the evidence standard. The level of specificity of such support may vary from circumstance to circumstance. But the special master here could properly find insufficient the reliance by Ms. LaLonde's expert on a theory that is unsupported by the literature to explain a sequence he had never seen before. Given that conclusion, the basis for Ms. LaLonde's petition reduces to a temporal relationship between the administration of the DTaP vaccine and M.L.'s focal brain injuries. As we have stated before, a temporal correlation alone is not enough to demonstrate causation. Moberly, 592 F.3d at 1323.
VI. CONCLUSION
In this case, as in Moberly, the special master and the Court of Federal Claims applied the correct legal standard and found, based in part on the unconvincing nature of Dr. Kinsbourne's testimony, that the petitioner failed to prove causation by a preponderance of the evidence. That judgment has not been shown to be legally or factually erroneous. We therefore affirm the judgment of the Court of Federal Claims.
