The safety of each vaccine is thoroughly studied before it is approved for use.
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.
Vaccine safety monitoring is ongoing.
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 immunization provider/clinic or health care provider. Health care providers report these events to the correct channels to monitor vaccine safety. Learn more.
