VAERS Information

What is VAERS?

VAERSThe Vaccine Adverse Event Reporting System (VAERS) is a national vaccine safety surveillance program administered by the FDA and the CDC.

VAERS collects and analyzes information about adverse events that occur after the administration of U.S. licensed vaccines. By monitoring such events, VAERS helps to identify potential safety concerns that otherwise may not come to light before licensure. A frequently reported event can trigger research on that issue.

A VAERS form is NOT an incident report. It is not used for placing blame or tracking provider errors. Filing a VAERS does not reflect poorly on unit readiness.

How is the IHD involved with VAERS?

The Immunization Healthcare Division (IHD) can assist with completion and submission of the VAERS form. The IHD has a unique relationship with the CDC in that the IHD Clinical Services reviews all VAERS filed on recipients of military-funded vaccines. Clinicians perform a comprehensive review of the adverse event reported to VAERS. The focus is to provide appropriate clinical management and follow-up to ensure that vaccine safety and protection goals are optimized for all military beneficiaries.

When is a VAERS report mandatory?

VAERS filing is mandatory when:

  • Support Centerthere is a hospitalization, a life-threatening event or a permanent disability associated with a vaccine
  • resulted in time lost from duty (> 1 shift), injury, or reaction temporally associated with a vaccine *
  • the event is on the VAERS reportable events table
  • contamination of a vaccine lot is suspected

Not mandatory but strongly encouraged:

  • there is autoinoculation or contact transmission w/ smallpox vaccination *
  • resulted in permanent medical exemptions
  • the event is unexpected in nature or severity
  • there is any suspected vaccine-related event

There is no time restriction
Submitter need not prove causality

*Paragraph 2-10 of the Joint Regulation (AR 40-562, BUMEDINST 6230.15B, AFI 48-110_IP, CG COMDTINST M6230.4G) Immunizations and Chemoprophylaxis for Prevention of Infectious Disease has recommendations for VAERS submission. 

Who can report to VAERS?

Anyone can report to VAERS. The majority of VAERS reports are sent in by vaccine recipients, health care providers, and vaccine manufacturers. Vaccine recipients or their parent/guardian are encouraged to seek the help of their health care professional in filling out the VAERS form.

How do I submit a military VAERS report?

Check with your local MTF and command for information about local and service-specific reporting requirements.

Should I file a VAERS on all events that occur after vaccinations?

We encourage you to report any concerning reaction following vaccination to VAERS even if you cannot tell whether the vaccine or another product caused it. For a discussion of the difference between common side effects and adverse events, click here.

Why is it important to document and report a Vaccine Adverse Event?

  • It provides a signal to the FDA/CDC that there may be a safety concern for a particular vaccine or vaccine combination that needs a safety evaluation.
  • It provides MHS with feedback on vaccine events that result in military exemption or impact line of duty.
  • Alerts DHA-IHD on MHS-specific vaccine issues that need special consideration or further research.
