COVID-19

All eligible travelers should be up to date with their COVID-19 vaccines. Please seeYour COVID-19 Vaccinationfor more information.

It is recommended for travelers who plan on eating street food.

Hepatitis B

Recommended for unvaccinated travelers younger than 60 years old traveling to Canada. Unvaccinated travelers 60 years and older may get vaccinated before traveling to Canada.

Travelers are at risk of measles if they have not been fully vaccinated at least two weeks prior to departure, or have not had measles in the past, and travel internationally to areas where measles is spreading.All international travelers should be fully vaccinated against measles with the measles-mumps-rubella (MMR) vaccine, including an early dose for infants 6–11 months, according toCDC’s measles vaccination recommendations for international travel.

Rabies

Dogs infected with rabies are not commonly found in Canada.Rabies is commonly found in some terrestrial wildlife species and bats.If rabies exposures occur while in Canada, rabies vaccines are typically available throughout most of the country.Rabies pre-exposure vaccination considerations include whether travelers 1) will be performing occupational or recreational activities that increase risk for exposure to potentially rabid animals and 2) might have difficulty getting prompt access to safe post-exposure prophylaxis.Please consult with a healthcare provider to determine whether you should receive pre-exposure vaccination before travel.For more information, seecountry rabies status assessments.
