The Vaccine Adverse Event Reporting System (VAERS)

The Vaccine Adverse Event Reporting System (VAERS) is a national program that collects and analyzes reports of possible side effects or health problems that occur after vaccination. Healthcare providers, patients, and caregivers can submit reports, helping health officials monitor vaccine safety in real-time. VAERS does not determine if a vaccine caused an adverse event but helps identify patterns that may require further investigation. This system plays a key role in ensuring vaccines remain safe and effective for the public.
