Vaccine Adverse Event Reporting System Database

The Vaccine Adverse Event Reporting System (VAERS) is a national database that collects reports about possible side effects or health problems that occur after vaccination. Healthcare providers, patients, and others can submit reports to VAERS to help monitor vaccine safety. The system doesn't determine if a vaccine caused an issue, but it helps health officials identify patterns or concerns that may need further investigation. VAERS plays a key role in ensuring vaccines remain safe and effective for the public.
