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.

All Vaccines in VAERS

Complete list of 104 vaccines with adverse event reports in VAERS. Click any vaccine name to see detailed analysis including yearly trends, age breakdowns, and associated symptoms.

VAERS tracks every vaccine licensed in the United States. This page shows aggregate report counts — higher numbers typically reflect widespread use (e.g., COVID-19 and flu vaccines), not higher risk. Always consider denominators when interpreting these numbers.

Most Reported Vaccines

These vaccines have the highest number of reports in VAERS. Remember: more reports doesn't mean more dangerous — it often reflects widespread use.

Understanding the Numbers

  • • Higher report counts often reflect widespread use, not higher risk
  • • COVID-19 vaccines dominate recent reports due to mass vaccination campaigns
  • • VAERS captures temporal associations, not proven causal relationships
  • • Always consider background rates and reporting incentives
