Measles, Mumps and Rubella (MMR)

The MMR vaccine protects against infection from measles, mumps and rubella in one needle.
• Routinely given to all children after their first birthday.
• A 2nd dose of MMR is given to all children at 4 to 6 years of age as MMRV vaccine, which also protects against Varicella (Chickenpox).
• This vaccine may also be recommended for some adults based on risk factors and previous immunization history.
When given on the recommended schedule:
• 85-100% of those fully vaccinated are protected against measles after 1 dose.
• 76-95% of those fully vaccinated are protected against mumps.
• 95-100% of those fully vaccinated are protected against rubella.

• At this time there are no other ways to prevent these diseases.
• Hand washing and covering the mouth and nose while coughing/sneezing can help reduce the spread of disease.

• The risk of a serious reaction or side effect from this vaccine is much less than the risk of measles, mumps or rubella.
• If you experience any side effect worse than what is listed below, please seek medical advice and notify the health unit.


• Mild pain at injection site
• Redness and swelling where needle was given

Less Common

• Fever, feeling unwell and/or rash 6-23 days after the needle was given. This rash is not contagious and goes away in a few days.
• Swelling of salivary glands
• Enlargement of lymph nodes
• Joint symptoms


• Blood disorder called Thrombocytopenia (low platelet count) which effects how the blood clots. Most often resolves within 3 months after the needle was given.
• 1 in 1,000,000 people will develop swelling of the brain (encephalitis). 1 in 1000 of those with measles will also develop this swelling of the brain

• Anyone with an allergy to any of the vaccine components or who has had an allergic or anaphylactic reaction to this vaccine.

• This excludes allergy to eggs as the trace amount of egg protein in the MMR Vaccine appears to be insufficient to cause an allergic reaction.
• Hypersensitivity reactions that occur with MMR vaccination are usually due to other components of the vaccine (gelatin, neomycin).

• Anyone with a weakened immune system.
• Anyone who is pregnant. Women should delay pregnancy for one month after receiving a live vaccine.
• Anyone with active untreated tuberculosis (TB).
• Anyone who has had another live vaccine in the last 4 weeks
