What vaccinations do children need in Canada?

Canada's vaccination system provides free protection for children against serious infectious diseases through provincial and territorial immunization programs. Although schedules may vary between provinces, all Canadian children have access to comprehensive vaccination from birth to adolescence.

1. General vaccination system in Canada

National structure

The National Advisory Committee on Immunization (NACI) provides recommendations on the use of vaccines in Canada, but each province and territory determines its own optimal schedule based on these recommendations, local data, and evidence. All recommended childhood vaccines are provided free of charge regardless of province of residence.

Key vaccination milestones

Children are usually vaccinated at the following ages:

  • Birth to 2 months
  • 4 months
  • 6 months
  • 12 months
  • 18 months
  • 4–6 years

  4. Update your immunization record.

Following this schedule and working closely with healthcare professionals will ensure that your child is well protected against serious diseases in Canada.
