CDC Recommendations on MMR Vaccine

While there is no blanket statement the CDC can give on the MMR vaccine for adults they do have some recommendations, they are:

If an adult does not have evidence of immunity they should get at least one dose of MMR vaccine. Acceptable presumptive evidence of immunity against measles includes at least one of the following:

• Written documentation of adequate vaccination:
• One or more doses of a measles-containing vaccine administered on or after the first birthday for preschool-age children and adults, not at high risk
• Two doses of measles-containing vaccine for school-age children and adults at high risk, including college students and healthcare personnel
• Laboratory evidence of immunity
• Born before 1957 (they likely have immunity because the virus was in wide circulation then)

Adults born from 1957 up to 1989 may have received only one MMR shot and may benefit from a second dose. Since the vaccine is not recommended for everyone a person should talk with their provider.

Healthcare providers should not accept verbal reports of vaccination without written documentation as presumptive evidence of immunity.

Children:

The childhood recommendations are easier, it is:

Two doses of MMR vaccine, starting with the first dose at age 12 through 15 months and the second dose at age 4 through 6 years before school entry
