CDC Vaccine Adverse Event Reporting System (VAERS)

The CDC's Vaccine Adverse Event Reporting System (VAERS) is a national program that collects reports of health problems that happen after vaccination. Healthcare providers, patients, and caregivers can submit reports to help monitor vaccine safety. VAERS aims to detect potential side effects or patterns that may need further investigation, but it does not determine if vaccines caused these issues. Instead, it serves as an early warning system to ensure vaccines remain safe and effective, supporting ongoing safety assessments by health authorities.
