As an adult, do I need the MMR vaccine?
You do not need the MMR vaccine if you
•had blood tests that show you are immune to measles, mumps, and rubella
•are someone born before 1957
•already had two doses of MMR or one dose of MMR plus a second dose of measles vaccine
•already had one dose of MMR and are not at high risk of measles exposure
You should get the measles vaccine if you are not among the categories listed above, and
•are a college student, trade school student, or other student beyond high school
•work in a hospital or other medical facility
•travel internationally, or are a passenger on a cruise ship
•are a woman of childbearing age
Do people who received MMR in the 1960s need to have their dose repeated?
Not necessarily. People who have documentation of receiving LIVE measles vaccine in the 1960s do not need to be revaccinated. People who were vaccinated prior to 1968 with either inactivated (killed) measles vaccine or measles vaccine of unknown type should be revaccinated with at least one dose of live attenuated measles vaccine. This recommendation is intended to protect those who may have received killed measles vaccine, which was available in 1963-1967 and was not effective.
Why are people born before 1957 exempt from receiving MMR vaccine?
People born before 1957 lived through several years of epidemic measles before the first measles vaccine was licensed. As a result, these people are very likely to have had the measles disease. Surveys suggest that 95% to 98% of those born before 1957 are immune to measles. Note: The “1957 rule” applies only to measles and mumps—it does NOT apply to rubella.
