Immunization Information must be provided to the school nurse. By law, your child must have at least one dose of each required vaccine before they are permitted to enter school. PA LAW REQUIRES THAT WITHIN 5 DAYS OF STARTING SCHOOL, the Nurse's Office be provided with proof that your child has received all "Required Vaccines." If further doses of missing vaccine(s) are not medically appropriate during the first 5 days of school, then on or before the 5th day, you must submit a statement, signed by your health care provider, listing the date(s) the remaining dose(s) will be given. The Allegheny County Health Department provides vaccination services. You may call them @ 412-578-8062 for clinic location and hours. Contact the nurse's office for information on obtaining a Medical or Religious / Moral Exemption.
