Oklahoma State Immunization Information System - OSIIS

This section provides information on the Oklahoma State Immunization Information System (OSIS), which is a statewide immunization registry operated by the Oklahoma State Department of Health, designed to collect and maintain accurate, complete, and current immunization records for Oklahomans of all ages. Since OSIIS began operations in 1994 and some clinics do not participate in OSIIS, it does not contain the immunization records of all Oklahomans.

How OSIIS Works

• Doctors and clinics record immunizations they have given in OSIIS.
• All of the immunizations given to an individual are entered into that person's record.
• When an individual visits a different clinic, that clinic can view the immunizations given previously.
• OSIIS provides official immunization records for school and childcare entry, camp entry requirements, and any other program that requires an immunization record.
• Clinics, schools, and childcare facilities can check OSIIS to determine what vaccines an individual has received.
• Keep in mind that if an individual received immunizations from a clinic that does not use OSIIS, those immunizations will not be recorded in OSIIS.

Benefits of OSIIS

• Provides a system that can maintain immunization records from many different clinics and doctor’s offices.
• Generates reminder postcards which are sent to parents when their children are "Due" or "Past Due" for immunizations.
• Saves parents time going to the doctor’s office or clinic to obtain a copy of their children’s immunization records because many schools can check immunization records online.
• Helps prevent children, adolescents, and adults from receiving vaccines they have already received.
• Provides schools and childcare facilities quick easy access to immunization records, even if the child received vaccines at more than one clinic.
