NO SHOT, NO SCHOOL: Pertussis Vaccinations (Tdap) Now Required for School Entry for All 7th Graders

By law, to attend school, all students entering the 7th grade in public and private schools must show proof that they have received a pertussis vaccine called Tdap. The Tdap vaccine protects them from three diseases: pertussis (also called whooping cough), diphtheria, and tetanus. Most adolescents received a different vaccine called DTaP as infants and young children to help protect them from the same diseases, but need to get a dose of Tdap vaccine now to boost their protection. The Tdap vaccine is recommended for children at 11 or 12 years of age and for teens who have not yet received a dose.

Students will need to show proof of vaccination before they start school. Though not required for school entry, adolescents should also receive meningococcal, human papillomavirus (HPV), and influenza vaccines. 

Visit for details about the requirement; implementation guidelines; and tools including FAQs, article templates, and forms.

  • All students entering into 7th grade are required to show proof that they received a pertussis vaccination (Tdap) to attend school. Students who do not meet this requirement and do not have a valid exemption will not be allowed to attend school.

  • Unvaccinated adolescents should get their pertussis vaccination (Tdap) now, along with any other vaccinations that they are due to receive, to help them meet the school requirement and stay healthy and in the classroom. Vaccinated students should provide proof that they received a Tdap dose, as requested by their school.

    • Because Td vaccine does not prevent pertussis, a record that reads “Td” or “Td/Tdap” will not meet the pertussis vaccination school requirement.
  • To meet the requirement, adolescents must have received a Tdap shot on or after their 7th birthday.* This shot protects them from pertussis, which is commonly called whooping cough, and two other serious diseases, diphtheria and tetanus.

  • If students have proof that they already received a Tdap vaccination (on or after their 7th birthday), they do not need another Tdap vaccine to attend school.

  • Tdap vaccines are required for school entry for all 7th graders, even if they have had pertussis. This is because a person who has had pertussis can get the disease again. 

  • Some students may be exempted from this requirement if there is a valid medical reason for not being vaccinated or if their parent chooses to exempt them due to their personal beliefs. However, this leaves the adolescent at risk for catching and spreading pertussis.

*A DTaP or DTP vaccination given on or after the seventh birthday will also meet the requirement.
