Vaccines are among the most strictly regulated medical products in Canada. All vaccines undergo an in-depth testing process and must be shown to be safe and effective before being approved for use in Canada. This process goes through several phases to gather all the scientific information necessary to ensure the safety and efficacy of the vaccine. Learn more.
After a vaccine is approved, its safety is continuously monitored. Canada has several systems in place to carefully monitor the safety of vaccines. It's important to report any adverse events after immunization to your doctor or local health unit. Health care providers are trained to report these events to the correct channels to monitor vaccine safety. Learn more.
