School Immunization Information
Information for parents and guardians about Pennsylvania's school immunization requirements.
Important Attendance Information
Students must meet Pennsylvania's school immunization requirements or have an applicable exemption. Students who do not meet the requirements may be excluded from school.
Required single-dose vaccines must be received before the first day of school. For a multidose series, a medically appropriate dose that is due at school entry must be received within the first five school days.
If additional doses are needed and cannot yet be given for medical timing reasons, a medical certificate must document the schedule for the remaining doses. Contact the school nurse and your child's health care provider to review your child's records and any required plan.
Pennsylvania School Requirements
The following summarizes requirements for kindergarten and attendance in subsequent grades. Your child's health care provider can confirm valid doses, spacing, and any catch-up needs.
Kindergarten & Grade-School Attendance
- Four doses of tetanus, diphtheria, and acellular pertussis vaccine, with one dose on or after the fourth birthday.
- Four doses of polio vaccine, with the fourth dose on or after the fourth birthday and at least six months after the previous dose.
- Two doses of measles, mumps, and rubella vaccine (MMR).
- Three doses of hepatitis B vaccine.
- Two doses of varicella (chickenpox) vaccine or evidence of immunity.
A fourth polio dose is not necessary if the third dose was administered at age four or older and at least six months after the previous dose.
Additional Requirements for Seventh Grade
In addition to the grade-school requirements, students entering seventh grade need:
- One dose of tetanus, diphtheria, and acellular pertussis vaccine (Tdap).
- One dose of meningococcal conjugate vaccine (MCV).
These doses are required on the first day of seventh grade. The same requirements apply when a student first enters in a succeeding grade.
Exemptions & Outbreaks
Pennsylvania permits exemptions for medical reasons, religious beliefs, or philosophical / strong moral or ethical convictions. Contact the school nurse about required documentation.
Students with exemptions may still be excluded from school during an outbreak of a vaccine-preventable disease.
What Families Should Do
- Review your child's immunization record with their pediatrician or other health care provider.
- Contact the school nurse for instructions on submitting records, medical certificates, or exemption documentation.
- Address missing records or doses before school begins whenever possible.
For PreK enrollment, ask the school nurse which age-appropriate immunization requirements and documentation apply.
