Measles, Mumps, Rubella & Varicella (MMRV)

The MMRV vaccine protects against infection from measles, mumps, rubella and varicella in one needle.
  • Routinely given to all children at 4 to 6 years of age as their 2nd dose of measles, mumps, rubella and varicella vaccine.
When given on the recommended schedule:

• 99% of those fully vaccinated are protected against measles.
• 97.4% of those fully vaccinated are protected against mumps.
• 100% of those fully vaccinated are protected against rubella.
• 98% of those fully vaccinated are protected against varicella.

• 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, rubella or varicella.
• If you experience any side effect worse than what is listed below, please seek medical advice and notify the health unit.


• Pain and redness where needle was given.
• Low grade fever.
• Measles/rubella/varicella like rash where needle was given.
• Moderate fever (higher than 39°C or 102.2°F).

Less Common

• 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.


• Anaphylaxis

  • 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 MMRV Vaccine appears insufficient to cause an allergic reaction.
• Hypersensitivity reactions that occur with MMRV 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.
