Immunization has saved more lives in Canada in the last 50 years than any other health measure.
Canada has a very thorough system to approve new vaccines for human use. Only vaccines that have been shown to be safe are approved. Once approved for use, all vaccines are closely monitored by public health officials and Health Canada for their safety. The COVID-19 vaccines currently used in Canada have been administered to millions of people around the world and have been shown to be both safe and effective.
