How to find your own vaccination records
Every U.S. state runs an Immunization Information System (IIS) — a registry that stores vaccine records reported by providers. Public access varies: some states offer a self-service online portal, others require a written request, and a few only release records through your provider.

Request form
Submit a form, they respond
Fill out a paper or online request; the health department mails or emails your records back — usually 1–4 weeks.
Provider only
Ask the administering clinic
No public access — records must be requested through the provider who gave you the shots, or your primary care office.

Important caveats about state immunization registries
- Coverage varies. Most state registries did not begin collecting adult records reliably until the 2000s or 2010s. If you were vaccinated as a young child before your state's registry existed, your records may not be in the system at all.
- Cross-state gaps. Registries are state-based. If you were vaccinated in one state and moved to another, your new state's IIS almost certainly doesn't have those records.
- Provider-reported. Records only appear if the provider who administered the vaccine reported them to the registry. Pharmacy shots, workplace flu clinics, and old military records often do not.
- If you cannot find your records, most schools and employers will accept a quantitative titer as proof of immunity for MMR, varicella, hepatitis A, and hepatitis B — often faster than tracking down old records.
