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.

Understanding Manufacturer Data

•Market presence matters: More reports often reflect more doses distributed, not necessarily more safety issues.
•Reporting varies: Newer vaccines and those under heightened scrutiny tend to have higher reporting rates.
•All manufacturers meet FDA standards: Safety and efficacy requirements apply equally to all approved vaccines.
