Based on extensive research, the World Health Organization, Health Canada and the Public Health Agency of Canada have concluded that vaccines do not cause autism.
Vaccines are extensively tested and manufacturers must submit scientific and clinical evidence to Health Canada demonstrating their vaccines meet safety, efficacy and quality requirements.
Getting your child vaccinated protects them and helps keep our communities safe. When it comes to your family’s health, lean on trusted medical experts, like your health care provider, to answer your questions and get reliable, scientific, evidence-based information.
