Vaccine Adverse Events Reporting System (VAERS)

The National Childhood Vaccine Injury Act of 1986 requires all health professionals and vaccine manufacturers report specific adverse events (possible side effects) that occur after the administration of routinely recommended vaccines. Those reports are submitted via the Vaccine Adverse Event Reporting System (VAERS).

Adverse events that must be reported include:

  • Any adverse event listed by the vaccine manufacturer as a contraindication to further doses of the vaccine; or
  • Any adverse event that occurs within the specified time period after vaccination.

Individuals may report any adverse event (possible side effect) that occurs after the administration of a vaccine licensed in the United States, even if they are unsure whether a vaccine caused the event.
