In Oregon, children are required to have certain immunizations or an exemption to attend public and private schools, preschools, Head Starts, and certified child care programs. The law covers nearly 700,000 students in 3,500 schools and child care facilities. Immunization and exemption records are reviewed every year to ensure children get the shots they need to provide the best protection to themselves and their community. The data below reflect the immunization rates for the school required vaccines. Statewide rates include public, private and online schools. School data are from the Immunization Primary Review Summary reports, collected annually in March by the Oregon Health Authority.
