Oklahoma State Immunization Information System
OSIIS is a centralized immunization registry that keeps electronic records of vaccines given by health care providers who use the registry.


OSIIS was started in 1994 so it does not have the records of all Oklahoma children. Also, some doctors and clinics do not use OSIIS. Therefore their records may not be complete.

Childcare Centers and Schools
If you cannot locate your child’s personal record or the record from your doctor, it may be necessary to repeat some of the vaccines or arrange for blood tests to document immunity to a particular disease.
County health departments in Oklahoma do not provide blood testing to determine immunity, but some private clinics and laboratories do offer this service.

Out of State Records
If your child received vaccines in another state you can check that state immunization website for information on the state's immunization registry.


Health Care Providers
Check with all your child's previous health care providers. They should have records of any immunizations they conducted.
