Data source: VAERS (Vaccine Adverse Event Reporting System)

Data through 2026 · Updated quarterly

Built by TheDataProject.ai · © 2026 VaccineWatch

Important: VAERS accepts reports of adverse events following vaccination. For any given report, there is no certainty that the reported event was caused by the vaccine. Reports may contain information that is incomplete, inaccurate, coincidental, or unverifiable. Most reports to VAERS are voluntary, which means they are subject to biases. This data cannot be used to determine if vaccines cause or contribute to adverse events.

⚠️

Important: VAERS reports alone cannot determine if a vaccine caused an adverse event. Reports may contain incomplete, inaccurate, or unverified information. Correlation does not equal causation.

Vaccine Severity Profile

Select any vaccine to see its complete outcome profile — recovery rates, hospitalization rates, death reporting rates, and how they compare to the average across all vaccines.

⚠️ Critical Context

  • • These are reporting rates, not actual risk rates. VAERS captures a subset of adverse events — the actual incidence may be higher or lower.
  • • "Higher than average" does NOT mean dangerous. Vaccines given to older/sicker populations will naturally have higher severity rates.
  • • Recovery data is often incomplete. Many reporters never submit follow-up, so "not recovered" may just mean "no update filed."
  • • Always consider the denominator — a vaccine given to 300 million people will have very different report rates than one given to 1 million.
