Wallach, Circuit Judge
Appellants Laura Oliver and Eddie Oliver, Jr. (together, "the Olivers"), parents and legal representatives of E.O., III ("E.O."), sued the Secretary of Health and Human Services ("the Government") for compensation under the National Childhood Vaccine Injury Act of 1986 ("Vaccine Act"), Pub. L. No. 99-660, 100 Stat. 3755 (codified as amended at 42 U.S.C. §§ 300aa-2 - 300aa-33 (2012) ). The Olivers allege that E.O. developed Dravet syndrome1 as a result of certain vaccinations. The Chief Special Master of the U.S. Court of Federal Claims determined that, inter alia, the Olivers "failed to show by preponderant evidence that E.O.'s injuries were caused by his ... vaccinations," such that the Olivers were not entitled to compensation. Oliver v. Sec'y of Health & Human Servs. (Oliver I ), No. 10-394V, 2017 WL 747846, at *2 (Fed. Cl. Feb. 1, 2017).
*1360The Olivers filed a motion for review in the Court of Federal Claims, and the Court of Federal Claims denied it. See Oliver v. Sec'y of Health & Human Servs. (Oliver II ), 133 Fed.Cl. 341, 344 (2017) ; see also J.A. 52 (Judgment).
The Olivers appeal. We have jurisdiction pursuant to 28 U.S.C. § 1295(a)(3) (2012). We affirm.
BACKGROUND 2
On April 9, 2009, E.O. visited a pediatrician for his six-month visit and received vaccinations for Diphtheria-Tetanus-acellular Pertussis, Hepatitis B, Inactivated Poliovirus, Pneumococcal Conjugate, and Rotavirus. Oliver I , 2017 WL 747846, at *4. At approximately 11:30 PM that night, Mrs. Oliver "found E.O. seizing in his bed" and called 9-1-1. Id. (citation omitted). When he arrived at the emergency room, E.O. presented with "a fever of 101.3 degrees, red eyes with discharge from his right eye, and a runny nose." Id. (internal quotation marks and citation omitted). The emergency room physician diagnosed E.O. with a febrile seizure and discharged E.O. with instructions to see his pediatrician. Id . On April 10, 2009, E.O.'s pediatrician recorded E.O.'s temperature as 97.1 degrees and diagnosed E.O. with "complex febrile seizure and conjunctivitis in the right eye." Id. (citation omitted).
"E.O. did not have any health issues or seizures for the next two months." Id. However, E.O. had several seizures over the summer of 2009 and began to experience prolonged seizures in March 2010, with each seizure resulting in an emergency room visit. Id. at *5. In April 2010, E.O. was referred to a pediatric neurologist, who diagnosed E.O. with an SCN1A gene defect in June 2010. Id. at *5-6. In July 2010, E.O. began to exhibit developmental delay, and the pediatric neurologist performed general physical, neurological, and motor examinations, which demonstrated "intractable, symptomatic childhood absence and complex partial seizures of independent hemisphere origin secondary to SCN1A gene defect (borderline SMEI syndrome) and encephalopathy characterized by speech delay." Id. at *6 (internal quotation marks and citation omitted).
DISCUSSION
I. Standard of Review and Legal Standard
"We review an appeal from the Court of Federal Claims in a Vaccine Act case de novo, applying the same standard of review [as the Court of Federal Claims] applied in reviewing the special master's decision." Milik v. Sec'y of Health & Human Servs ., 822 F.3d 1367, 1375 (Fed. Cir. 2016) (citation omitted). "Although we review legal determinations without deference, we review the special master's factual findings under the arbitrary and capricious standard." Id. at 1376 (citation omitted). This standard is "uniquely deferential" and "difficult for an appellant to satisfy with respect to any issue, but particularly with respect to an issue that turns on the weighing of evidence by the trier of fact." Id. (internal quotation marks and citations omitted). "[A]s long as the special master's conclusion is based on evidence in the record *1361that is not wholly implausible, we are compelled to uphold that finding as not being arbitrary or capricious." Id. (internal quotation marks, brackets, and citation omitted).
Where, as here, a petitioner alleges an injury not found on the Vaccine Injury Table ("the Table"),3 they "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 , 592 F.3d at 1321 (internal quotation marks and citation omitted). To demonstrate causation, the petitioner's "burden is to show by preponderant evidence" each of the requirements set forth in Althen v. Secretary of Health and Human Services ("the Althen prongs"): "(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." 418 F.3d 1274, 1278 (Fed. Cir. 2005). "If [the petitioner] satisfies this burden, she is entitled to recover unless the [G]overnment shows, also by a preponderance of evidence, that the injury was in fact caused by factors unrelated to the vaccine." Id. (internal quotation marks, brackets, and citation omitted).
II. The Court of Federal Claims Did Not Err in Sustaining the Chief Special Master's Determination
The Chief Special Master determined that the Olivers failed to satisfy their burden as to each of the Althen prongs. Oliver I , 2017 WL 747846, at *11-21. The Olivers aver that the Chief Special Master erred in her evaluation of the Althen prongs by: (1) "misappl[ying] Daubert [v. Merrell Dow Pharmaceuticals, Inc. , 509 U.S. 579, 113 S.Ct. 2786, 125 L.Ed.2d 469 (1993) ] and thus appl[ying] an evidentiary standard not in accordance with law," Appellants' Br. 17 (capitalization modified); see id. at *17-33 ; and (2) "improperly using estoppel and a faulty scientific premise to deny both a full and fair hearing, in an abuse of her discretion, as well as a finding of causation," id. at *34 (italics omitted); see id. at *34-43. We disagree with the Olivers.
First, although the Olivers claim that the Chief Special Master misapplied Daubert , their argument amounts to no more than a challenge to the weight afforded to their expert's testimony and supporting evidence.4 See id. at *17-33. The Chief Special Master thoroughly evaluated both parties' evidence as to each Althen prong and found the Government's more persuasive. See *1362Oliver I , 2017 WL 747846, at *11-21. For example, regarding the first Althen prong, the Chief Special Master found that "none of the articles cited by [the Olivers' expert] suggest that vaccines can cause ... or change the clinical course of Dravet syndrome, and several come to the opposite conclusion," whereas the Government's expert "provide[d] strong evidence [in the form of animal studies] that Dravet syndrome will develop in children with the SCN[1]A mutation, whether or not they receive vaccinations." Id. at *16 ; see id. at *11-16 (reviewing the parties' evidence as to the first Althen prong). In light of these findings, the Chief Special Master determined that the Olivers' expert "did not provide a 'sound and reliable' medical theory to explain how the vaccinations at issue cause Dravet syndrome." Id. at *16. The Chief Special Master made similar findings with respect to the second and third Althen prongs. See id . at *16-20 (reviewing the parties' evidence as to the second Althen prong), *20 (finding, with respect to the second Althen prong, that the Olivers' expert's testimony was "not persuasive" in light of the Government's expert's testimony and E.O.'s medical records, such that the Olivers "failed to prove by a preponderance of the evidence a logical sequence of cause and effect showing that the vaccines E.O. received caused his Dravet syndrome"), *20-21 (reviewing the parties' evidence as to the third Althen prong), *21 (finding, with respect to the third Althen prong, that, "[w]hile the proximity between vaccination and seizure onset might suggest a causal relationship between the two events, E.O. did not develop Dravet syndrome until ... more than a year after these vaccinations," such that the Olivers' evidence "[wa]s not sufficient to establish a causal link").
The Olivers repeatedly fault the Chief Special Master for failing to afford greater weight to their expert's testimony and supporting evidence. See, e.g. , Appellants' Br. 25 (stating that "the [Chief] Special Master is highly dismissive of all of [their expert]'s testimony"), 26 (stating that the Olivers' expert's "theory and ... mechanisms were, in fact, supported by the literature even if his conclusions were not yet published"), 33 (stating that the Chief Special Master "essentially reject[ed]" their expert's supporting evidence). We cannot review such challenges. See Milik , 822 F.3d at 1376 ("[W]e do not reweigh the factual evidence, assess whether the special master correctly evaluated the evidence, or examine the probative value of the evidence or the credibility of the witnesses-these are all matters within the purview of the fact finder." (internal quotation marks and citation omitted) ); Lampe v. Sec'y of Health & Human Servs. , 219 F.3d 1357, 1362 (Fed. Cir. 2000) (stating that "assessments of the credibility of the witnesses and the relative persuasiveness of the competing medical theories of the case" "are virtually unchallengeable on appeal"). Therefore, we hold that the Chief Special Master did not misapply Daubert in weighing the parties' experts' testimony and supporting evidence and that the Chief Special Master's factual findings were neither arbitrary nor capricious. See de Bazan v. Sec'y of Health & Human Servs. , 539 F.3d 1347, 1352 n.4 (Fed. Cir. 2008) (rejecting similar arguments on the grounds that " Daubert is inapposite here because the special master did not exclude any expert evidence under Daubert " and, instead, "admitted and weighed both parties' evidence but simply decided that the [G]overnment's evidence was more persuasive"); Terran ex rel. Terran v. Sec'y of Health & Human Servs. , 195 F.3d 1302, 1316 (Fed. Cir. 1999) (affirming a "[s]pecial [m]aster's *1363analysis ... using Daubert [ ] ... as a tool or framework for conducting the inquiry into the reliability of the evidence," where the special master's "application of the Daubert factors [was] reasonable," because "[t]he [s]pecial [m]aster found that the Daubert inquiry raised serious questions about the [petitioner's expert's] testimony," such that "the proffered theory of causation was not sufficiently reliable").5
Second, the Chief Special Master did not apply estoppel to either deny a fair hearing or bar the Olivers' theory of causation. The Olivers assert that the Chief Special Master "effectively estopped the [Olivers] from fully presenting [their] case," Appellants' Br. 39, by noting that, "[t]o date, there have been at least [fifteen] other ... cases which involved children with SCN1A mutations[ ] and compensation has been denied in all of these cases," Oliver I , 2017 WL 747846, at *1 (footnote omitted); see id. at *1 n.3 (listing the prior cases); see also Estoppel , Black's Law Dictionary (10th ed. 2014) (defining estoppel as, inter alia, "[a] bar that prevents the relitigation of issues"). However, one reference to other cases rejecting similar claims does not constitute the application of estoppel. Cf. Waymo LLC v. Uber Techs., Inc. , 870 F.3d 1350, 1361 (Fed. Cir. 2017) ("We will not find legal error based upon an isolated statement stripped from its context." (internal quotation marks and citation omitted) ). Indeed, the Chief Special Master made no reference to estoppel, see generally Oliver I , 2017 WL 747846, and the Olivers concede that they cannot identify where the Chief Special Master applied *1364estoppel to bar their claims, see Oral Arg. at 2:04-41 (acknowledging that the Chief Special Master's opinion did not apply equitable estoppel and failing to identify any authority for finding an improper application of equitable estoppel under those circumstances). As we explained above, the Chief Special Master thoroughly considered the parties' evidence and found the Government's more persuasive, Oliver I , 2017 WL 747846, at *11-27, and we may not reweigh that evidence on appeal, see Milik , 822 F.3d at 1376.6
CONCLUSION
We have considered the Olivers' remaining arguments and find them unpersuasive. Accordingly, the Judgment of the U.S. Court of Federal Claims is
AFFIRMED
