  • 1 dose of tetanus, diphtheria, acellular pertussis (Tdap) 

  • Students must have the Tdap and first MCV to be able to enter 7th grade.

Exclusion From School

In accordance with the above regulation, since you have provided evidence of at least one dose of each vaccine, your child may attend school provisionally after “A plan for completion of the required doses” has been provided.  Your child must comply with current immunization law which requires completion of required immunizations or provide a medical certificate completed by a physician, certified registered nurse practitioner, physician assistant or local health department.  Any student who does not complete the required immunizations will be excluded from school until the requirement is met.

Medical Exemptions

Children need not be immunized if the family physician (M.D or D.O.) provides a written statement that immunization may be detrimental to the health of the child. When the physician determines that immunization is no longer detrimental to the health of the child, the child will have to comply with the above immunization requirements.

Religious Exemptions

Children need not be immunized if the parent/guardian or emancipated child objects in writing to the immunizations on religious grounds, or on the basis of strong moral or ethical conviction similar to a religious belief. The statement must be written on the back of the child’s “Certificate of Immunization” located in the school nurse’s office.
