What is measles, mumps, and rubella vaccine?

Measles, mumps, and rubella are serious diseases caused by viruses spread from person to person.

Becoming infected with rubella virus (also called German Measles) during pregnancy can result in a miscarriage or serious birth defects.

The M-M-R II is used to help prevent these diseases by causing your body to develop immunity to the disease. This vaccine will not treat an active infection that has already developed in the body.

MMR vaccine is for use in people 12 months of age and older who have never received the vaccine or had the diseases.
