Immunization Requirements for Attending School

Students aged 4–17 attending school in Ontario must be immunized according to Ontario’s Publicly Funded Immunization schedule. Being fully immunized protects students against many diseases that are easily spread in schools.

Grade 7 Immunizations

The Health Unit provides immunizations in local schools for Grade 7 students. Grade 7 students have the opportunity to receive up to three vaccines at school, at no cost: Hepatitis B, Human Papilloma Virus (HPV) (Gardasil 9), and Meningococcal ACYW-135 (Menactra). Hepatitis B and HPV are voluntary vaccines. Meningococcal vaccine is required for students to attend school in Ontario.

Immunizations for Children

Immunization is a safe and effective way to protect children from vaccine preventable diseases. Routine immunizations in Ontario begin at two months of age and continue throughout life. All routine childhood immunizations are free and can be given by the child’s Health Care Provider. If they do not have a Health Care Provider, the child can be immunized at one of the Health Unit’s immunization clinics.
