An up to date immunization record is required prior to your child's first day of enrollment here, except when California State Law allows exemption for one or more immunizations based on rare medical issues. No child will be admitted to Saint Mark's without the required immunizations or a letter signed by a pediatrician for medical reasons. Children entering preschools at age 2 and older should have received immunizations as follows: 3 doses of Polio, 4 doses of DTP, 3 doses of Hepatitis B, 1 dose of Varicella (chicken pox), 1 dose of MMR, 1 or 3 does of HIB (one is sufficient if given after a child’s first birthday). As part of the enrollment packet, a signed doctor’s form is also required including immunization record and details of a child’s general health status.
