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.

This website is for Canadians, including healthcare consumers and providers, who are seeking reliable information on immunization for all ages. It is developed, published, managed and updated regularly by the Secretariat for Immunize Canada, and the content is reviewed by immunization experts.


During National Immunization Awareness Week, you will see increased publicity about the importance of immunization and the success and impact that immunization has had in protecting and saving lives. Many organizations, in Canada and around the world, participate in international strategies to raise awareness about the important role of vaccines.

Immunize Canada invites you to help celebrate National Immunization Awareness Week with us from 21 to 28 April 2018.
