MMR VACCINE

The MMR vaccine is a live, attenuated (weakened), combination vaccine that protects against the measles, mumps, and rubella viruses. It contains the safest and most effective forms of each vaccine.

When this vaccine virus is given to a child, it replicates only a little before it is eliminated from the body. This replication causes the body to develop an immunity that, in 95% of children, lasts for a lifetime.

A second dose of the vaccine is recommended to protect those 5% who did not develop immunity in the first dose and to give "booster" effect to those who did develop an immune response.

Who should have the MMR vaccine?

You do NOT need the measles, mumps, rubella vaccine (MMR) if:

• You had blood tests that show you are immune to measles, mumps, and rubella.
• You are a man born before 1957.
• You are a woman born before 1957 who is sure she is not having more children, has already had rubella vaccine, or has had a positive rubella test.
• You already had two doses of MMR or one dose of MMR plus a second dose of measles vaccine.
• You already had one dose of MMR and are not at high risk of measles exposure.
