Access the New Immunization Requirements Webpage for Families at Designed to help parents understand the rules around school and childcare immunizations, it has all the forms families need to meet the immunization requirements in English and Spanish.

Updated Immunization Requirement Charts for the 2023-24 school year are posted in the Immunization Requirements section on the school and child care immunization webpage The main changes are:

  • Grade roll-up of the grandfathered Tdap age:
  • Grade 7-10 must have a Tdap at age 10+
  • Grade 11-12 can meet the requirement with a Tdap at age 7+
  • Polio vaccine will be required for all students, even those age 18+

Updated Guidance: Students four years old by Sept 1st of the School Year

Students in preschool or kindergarten (including Transitional Kindergarten) who are four years old on September 1st of the school year are required to have the additional dose of DTaP and IPV given at age four and the 2nd dose of MMR and varicella vaccines. Getting these doses can be difficult for late summer birthdays, so the following footnote is added to the school chart:

“Must have additional DTaP IPV, MMR, Varicella vaccine by the 1st day of school or within 30 days after 4th birthday, whichever is later”.
