CDC VAERS Reporting System

• Who reports
  • Healthcare providers
  • Vaccine manufacturers
  • The public 
• Interpretation
  • VAERS data are derived from a passive surveillance system and represent unverified reports of health events, both minor and serious, that occur after vaccination.
  • While some events reported to VAERS are truly caused by vaccines, others may be related to an underlying disease or condition, to drugs being taken concurrently, or may occur by chance shortly after a vaccine was administered.
  • In some media reports and on some web sites on the Internet, VAERS reports are presented as verified cases of vaccine deaths and injuries. Statements such as these misrepresent the nature of the VAERS surveillance system.
