VAERS Reporting
Vaccine Adverse Event Reporting System

Report a reaction after a vaccination

A faster, guided way to file a VAERS report — on any device, in English or Spanish. We ask only what applies to you, save your progress as you go, and help at every step.

Medical emergency? If you are experiencing a medical emergency, call 9-1-1 or seek care immediately. VAERS is for reporting, not medical advice.
