Common Questions

Who Can Report?

Anyone can submit a report — patients, parents, caregivers, and healthcare providers. Healthcare providers are required to report certain events.

Why Report?

VAERS helps CDC and FDA monitor vaccine safety. Reporting does not mean the vaccine caused the problem — all reports are valuable for safety monitoring.

What Happens Next?

After submission, you'll receive a confirmation number. VAERS staff may contact you if additional information is needed.
