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.

Reports by State

Geographic distribution of VAERS adverse event reports across U.S. states and territories. Higher numbers typically reflect larger populations, not higher risk.

State-level data reveals reporting patterns influenced by population size, healthcare infrastructure, and reporting culture. Per-capita rates help normalize for population differences, though they still don't account for varying vaccination rates or reporting awareness between states.

Understanding State Data

•Population matters: California and Texas lead in reports largely because they are the most populous states
•"Unknown" state: Many reports don't include state information, which is why "UNK" appears high
•Reporting culture: Some states may have higher reporting rates due to healthcare provider awareness or mandate requirements
