Find immunization and exemption data
Oregon school immunization and exemption data can be found on the Oregon Health Authority website, which provides the most up-to-date county- and school-level immunization data. Schools must share their immunization and exemption rates for each vaccine required for school attendance twice a year:
- Within 30 days of the beginning of the school year.
- Within 30 days after Exclusion Day, which is always the third Wednesday in February.

The state aims for at least 95% of children to be immunized for community protection, though the percentage varies by disease. When 95% of children are vaccinated in a school or child care, this significantly reduces the chance of spreading the disease among vulnerable individuals.
Senate Bill 895 is a law about school immunizations that went into effect during the 2015-2016 school year and continues today. Key changes made by Senate Bill 895:
Religious exemptions signed prior to March 1, 2014 are no longer valid. Parents who are requesting a non-medical immunization exemption will now be required to complete the new two-step process below prior to Exclusion Day in February.
- Certificate of Immunization Status (CIS) form obtained from your child’s school office – fill in the dates of any vaccines your child has received, and fill out the nonmedical exemption section of the form by marking the vaccines for which you would like an exemption, and sign the form; AND
- Vaccine Education Certificate—get this certificate after receiving the required education about immunizations from your child’s health care provider or after watching the online vaccine education module.
Schools and children’s facilities will be required to have their immunization and exemption rates available at their main offices, on their websites (this page serves that need) and for parents on paper or electronic format.
