Immunization - School Age Children

Student immunization programs have been going on for many years in Ontario, safely protecting our children in schools and in the community. Infectious diseases can spread at school amongst children and adolescents who are not vaccinated. As a parent, you can keep your kids healthy with routine health care and vaccinations. Make sure your children are up-to-date according the Child and Early Years Act, 2014 (for children under the age of 4 years old in licensed child care centres) and the Immunization of School Pupil's Act (for students 4-17 in elementary and secondary schools). The Middlesex-London Health Unit screens records of children attending school to ensure they are complete. Clinics are also offered in grade 7 for three types of vaccines students are eligible for.


Grade 7 Immunization Program

Clinics are held in elementary schools in London and Middlesex County throughout the school year.

Student Record Review

Did you receive a letter from the Health Unit? Every year the Middlesex-London Health Unit reviews records of students that attend elementary and secondary school to ensure their immunizations are up-to-date.
