Tdap Required for 7th Grade School Entry

In Washington State, the Tdap vaccine is required for school attendance in certain grades. The Tdap is a booster vaccine which continues to protect your child against tetanus, diphtheria, and pertussis - diseases they were immunized against as a young child.

This is a reminder that as of August 1, 2020 the Tdap school requirement has changed to 7th grade to better align with the updated 2019 national immunization schedule In the past, the Tdap booster was required starting at 6th grade.

For the 2022-2023 school year, all students attending 7th grade must have had one dose of the Tdap vaccine given at or after age 10 to be accepted for school entry. Students who are not up to date will not be allowed to start school on the first day of school.

Please review your student’s immunization records to ensure they are compliant with the law. If you are unsure if your student is up to date, please reach out to your healthcare provider. 

To update your child’s Tdap immunization record at school, you will need to turn in a medically verified immunization record to your school nurse. Your child’s health care provider can print this for you, or you can print it from MyIR or MyIRMobile, which are free Department of Health online tools that allow families to view and print their official immunization records. For detailed information about how to get access to MyIR or MyIRMobile visit:

If you have already given the school documentation that your child has had the required Tdap vaccine or your child has a valid exemption on file with their school, no further action is needed.

Exemptions may be claimed for personal/philosophical, religious or medical reasons. Measles, mumps, and rubella may not be exempted for personal/philosophical reasons. To request an exemption a completed Certificate of Exemption must be submitted to the school or child care center.
