Report an Adverse Event

Doctor consulting patient on how to report to VAERS

Online reporting is strongly encouraged. Please report clinically important adverse events that occur after vaccination of adults and children, even if you are not sure whether the vaccine caused the adverse event.

The Vaccine Adverse Event Reporting System (VAERS) accepts all reports, including reports of vaccination errors. Guidance on reporting vaccination errors is available if you have additional questions.

Knowingly filing a false VAERS report is a violation of Federal law (18 U.S. Code § 1001) punishable by fine and imprisonment.

Two Ways to Submit an Online Report to VAERS


What will I need to fill out the report?

  • Patient information (age, date of birth, sex)

  • Date, time, and location administered
  • Date and time when adverse event(s) started
  • Symptoms and outcome of the adverse event(s)
  • Medical tests and laboratory results (if applicable)

Privacy Protection

Information identifying the person who received the vaccine and the person who filed the report is not made available to the public. You or your health care provider may be contacted for further information after your report is received.
