VaccineWatch is an independent data and information platform that provides transparent access to the Vaccine Adverse Event Reporting System (VAERS). Built by TheDataProject. ai, it organizes publicly available CDC and FDA reports into searchable tools, dashboards, comparisons, and educational resources covering data from 1990 onward.

Visitors can explore reports by vaccine, symptom, manufacturer, and state, or use interactive features such as reporting-rate calculations and signal-detection analysis. The site also offers vaccine side-effect guides, a schedule resource, a glossary, a FAQ, and in-depth articles on topics including reporting patterns, onset timing, vaccine lots, and the impact of COVID-19 on VAERS. VaccineWatch emphasizes context alongside its figures and explains how reports are collected and published.

It clearly cautions that VAERS reports describe events occurring after vaccination and do not establish that a vaccine caused them; submissions may also be incomplete, inaccurate, coincidental, or unverified. Its stated aim is to support informed decision-making through access to data and analysis, rather than to draw conclusions about vaccine safety from raw report counts alone
