O'Connor, J., concurring
Examining the language of § 300aa-11(c)(1)(C)(i), the Court properly rejects the Court of Appeals' determination that a claimant may make out a prima facie "onset" case simply by proving that she experienced a symptom of a "table illness" within the specified period after receiving a vaccination. Ante, at 273-274. To establish a table case, the statute requires that a claimant prove by a preponderance of the evidence either (1) that she suffered the first symptom or manifestation of the onset of a table condition within the period specified in the table or (2) that she suffered the first symptom or manifestation of a significant aggravation of a pre-existing condition within the same period. As the Court rightly concludes, proof that the claimant suffered a symptom within the period is necessary but not sufficient to satisfy either burden; the word "first" is significant and requires that the claimant demonstrate that the postvaccine symptom, whether of onset or of significant aggravation, was in fact the very first such manifestation.
The Court relies on a commonsense consideration of the words "first" and "onset" in reaching this conclusion: "If a symptom or manifestation of a table injury has occurred before a claimant's vaccination, a symptom or manifestation after the vaccination cannot be the first, or signal the injury's onset." Ante, at 274. I find equally persuasive the observation that the Court of Appeals' reading deprives the "significant aggravation" language in the provision of all meaningful effect. The term "significant aggravation" is defined in the statute to mean "any change for the worse in a preexisting condition which results in markedly greater disability, pain, or illness accompanied by substantial deterioration of health." 42 U. S. C. § 300aa-33(4). If, as the Court of Appeals determined, a claimant makes out an "onset" case any time she can demonstrate that any symptom occurred within the relevant period, all cases in which children experience postvaccine symptoms within the table period become "onset" cases. The phrase "significant aggravation,"
