Immunize Canada

One hundred years ago, infectious diseases were the leading cause of death worldwide. In Canada, they now cause less than 5% of all deaths – thanks in part to immunization programs across the country.

Immunization protects individuals and communities by preventing the spread of disease. As more people are immunized the disease risk for everyone is reduced. Immunization has probably saved more lives in Canada in the last 50 years than any other health intervention. Immunization is the single most cost-effective health investment, making it a cornerstone in the effort to promote health.
