Vaccine Adverse Event Reporting System
The Vaccine Adverse Event Reporting System (VAERS) is a cooperative vaccine safety program of the Centers for Disease Control and Prevention (CDC) and the Food and Drug Administration (FDA). VAERS is a post-marketing safety surveillance program, collecting information about adverse events (possible side effects) that occur after the administration of U.S. licensed vaccines.
What Can Be Reported to VAERS?
VAERS seeks reports of any clinically significant medical event that occurs after vaccination, even if the reporter cannot be certain that the event was caused by the vaccine. VAERS encourages the reporting of any clinically significant adverse event that occurs after the administration of any vaccine licensed in the U.S. You should report adverse events even if you are unsure whether a vaccine caused the event.
Who Reports to VAERS?
Anyone can file a VAERS report, including healthcare providers, manufacturers, and vaccine recipients.
