Report an Adverse Event

en Español
Please report all significant 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.  VAERS is primarily concerned with monitoring adverse health events and we encourage reporting of clinically significant adverse health events following vaccination.  Using  clinical judgment, healthcare professionals can decide whether or not to report a medical error at their own discretion.  For example, a healthcare professional may elect to report vaccination errors that do not have an associated adverse health event, especially if they think the vaccination error may pose a safety risk (e.g., administering a live vaccine to an immunocompromised patient) or that the error would be preventable with public health action or education.

 There are three ways to report to VAERS-  
  1. Online
  2. Fax
  3. Mail

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.

Knowingly filing a false VAERS report with the intent to mislead the Department of Health and Human Services is a violation of Federal law (18 U.S. Code § 1001) punishable by fine and imprisonment.

The US Food and Drug Administration has issued new regulations, "Postmarketing Safety Reports for Human Drug and Biologic Products; Electronic Submission Requirements", which describes requirements for electronic submission of Individual Case Safety Reports (ICSRs), ICSR attachments and periodic reports to FDA.  For more information about electronic ICSR reporting to VAERS, refer to the FDA ICSR website: http://www.fda.gov/BiologicsBloodVaccines/DevelopmentApprovalProcess/ucm174963.htm or contact the FDA Electronic Submissions Help Desk at: esgprep@fda.hhs.gov.
