Centennial School District 28J

Oregon law requires specific vaccines for school and child care attendance based on age and grade level. Parents must submit proof their children are immunized against the specified diseases. Only medical or religious reasons will exempt children from provisions of the law. School administrators are required by Oregon law to deny admission to children who are not immunized.

Immunizations are available at all Multnomah County Student Health Centers. For current year immunization requirements, please see the flyers below:

Multnomah Education Service District: Immunization Information

Changes to Oregon Immunization Requirements (effective August 1, 2025)

1. A Certificate of Immunization Status (CIS) form with a parent signature documenting the date of chickenpox (varicella) disease will no longer be accepted to document immunity. Schools may accept parent signed history of varicalle disease only if received prior to August 1, 2025. 

Acceptable immunity documentation:

• A letter signed by a health care provider with authority to diagnose disease 
• A lab report with reference ranges
• A print out from the Alert Immunization Information System (ALERT IIS) showing immunity
• Documentation from a representative of a local health department

2. Exclusion Day is moving from the third Wednesday to the fourth Wednesday in February. This gives parents an extra week to provide immunization records or documentation of an exemption or immunity to the school. If the school does not have the required immunization records or documentation by Exclusion Day, the student will not be permitted to attend school.
