Immunization Coverage
Vaccine coverage refers to the proportion of a population that is appropriately immunized against a specific vaccine-preventable disease (VPD). Maintaining high immunization coverage is essential for the effective prevention and control of VPDs. PHO leads the provincial surveillance of immunization coverage, including the annual coverage assessment of school pupils for Ontario’s publicly-funded immunization programs.
To obtain or inquire about an immunization record, or for general immunization information, please contact your local public health unit.
