Measles is a highly contagious respiratory virus that causes a febrile rash illness and poses significant health risks.

The introduction of routine measles vaccination has led to a dramatic decline in the incidence of measles. Endemic measles has been eliminated in Canada since 1998. However, Canada continues to see measles cases related to travel. Measles can easily be spread to individuals who have not been previously infected or immunized against measles.

Staying up to date with vaccines:

Children

In Ontario, as a part of routine vaccinations children receive two doses of measles vaccine before the age of 7.

• Children receive one dose of the MMR vaccine (measles, mumps & rubella) at 12 months.
• Children receive a second dose of measles containing vaccine, MMRV vaccine (measles, mumps, rubella & varicella), between 4 and 6 years old.
• Infants 6-11 months: One dose of MMR vaccine may be given if infant is travelling outside of Canada. (Note: Two additional doses of measles-containing vaccine must be administered after the child is 12 months old to ensure long lasting immunity to measles).

Adults born before 1970

Generally assumed to have natural immunity. One dose of MMR vaccine is recommended prior to travel outside of Canada, unless there is lab evidence of immunity or history of lab- confirmed measles.

Born in 1970 or later

Adults born in or after 1970 likely received one dose of a measles-containing vaccine. In 1996, two doses became standard in Ontario.
Those who have only received one dose of MMR vaccine are eligible to receive a second dose if they meet any of the criteria below (only one booster is needed):

• Health care workers
• Post-secondary students
• Planning to travel outside of Canada
