Important Context

Association, not causation: These reports show No adverse event occurred after vaccination, not that the vaccine caused it.
Background rates: No adverse event may occur naturally at baseline rates in the population, unrelated to vaccination.
Anyone can report: VAERS accepts reports from anyone — patients, parents, healthcare providers — without requiring medical verification.
Denominator missing: VAERS counts reports, not rates per dose. Without knowing how many doses were given, raw counts can be misleading. Learn more →
