What is the measles vaccine?
The measles vaccine protects against the virus that causes measles infection.
Vaccines can provide protection against a single disease or can be made to provide protection against more than one disease. Vaccines that provide protection against more than one disease are called combined vaccines.
The measles vaccine is only available as a combined vaccine. It is always combined with mumps and rubella, and sometimes varicella. The vaccine you receive depends on your age, your vaccine requirements and the specific vaccine products that are currently available.

Who should get the measles vaccine?
In general, everyone should get this vaccine. It is given starting in infancy and again in early childhood. It is important to receive the vaccine at the right time. To find out more about when infants and children should get the measles vaccine, see the Ontario Immunization Schedule (Ontario Ministry of Health and Long-Term Care).
Who should not get the measles vaccine?
- People who have had a serious allergic reaction to any ingredient in the vaccine or to a previous dose of the vaccine itself should not receive the measles vaccine.
- Women should not get the vaccination while they are pregnant.
Your health care provider will ask you questions about your health before giving you any vaccine. This will help them identify allergies you might have and safely manage potential allergic reactions.
What are the possible side effects of the measles vaccine?
You could have mild side effects after being vaccinated, but they usually go away in one to two days. Some people can be allergic to the vaccine, just like they might have a food or medication allergy.
