MMR

The MMR vaccine (M-M-R II) protects against measles, mumps, and rubella. It is recommended that children receive two doses, at 12 - 15 months, and at 4 - 6 years. Adults may also be vaccinated. The vaccine is very effective—for example, one dose is estimated to be 93% effective at preventing measles, with two doses at 97%.
