Adverse Event Vaccine Reporting System (VAERS)

Vaccines are developed with the highest standards of safety. However, as with any medical procedure, vaccination has some risks. Individuals react differently to vaccines, & there is no way to foretell how individuals will react to a specific vaccine.
  • Detect new, unusual, or rare vaccine adverse events
  • Monitor increases in known adverse events
  • Identify potential patient risk factors for particular types of adverse events
  • Identify vaccine lots with increased numbers or types of reported adverse events
  • Assess the safety of newly licensed vaccines
Approximately 30,000 VAERS reports are filed yearly, with 10-15% classified as serious (leading to permanent disability, hospitalization, life-threatening illnesses or death). Somebody can file a VAERS document, including health care providers, manufacturers, & vaccine recipients or their parents or guardians. The VAERS form requests the following information:

  • The type of vaccine received
  • The timing of the vaccination
  • The onset of the adverse event
  • Current illnesses or medication
  • Past history of adverse events following vaccination 
  • Demographic information about the recipient
