Measles, mumps, and rubella are infections that can lead to significant illness. More than 95% of children receiving the MMR vaccine will be protected from the three diseases throughout their lives.
All children should get the first dose of MMR vaccine at age 12 to 15 months and second dose at age 4 to 6 years.
All adults with no evidence of immunity should get 1 dose the MMR vaccine and 2 doses if in the high-risk group.
