State law (MS 121A.15) requires that each student in a Minnesota school be protected from childhood diseases by receiving immunizations. Parents may obtain a legal exemption for medical reasons or conscientious beliefs. All students new to Saint Paul Public Schools must bring their immunization records or exemption record to the Student Placement Center when they enroll in school. Immunizations include diphtheria, pertussis and tetanus (Dtap/Tdap); polio; measles, mumps and rubella (MMR); Hepatitis B and varicella (chicken pox).
