You do not need measles, mumps, and rubella (MMR) vaccine if you meet any of these criteria for evidence of immunity:
• You have written documentation of adequate vaccination:
o at least one dose of a measles, mumps, and rubella virus-containing vaccine administered on or after the first birthday for preschool-age children and adults not at high risk for exposure and transmission
o two doses of measles and mumps virus-containing vaccine for school-age children and adults at high risk for exposure and transmission, including college students, healthcare personnel, international travelers, and groups at increased risk during outbreaks
• You have laboratory confirmation of past infection or had blood tests that show you are immune to measles, mumps, and rubella.
• You were born before 1957.*
If you do not have evidence of immunity against measles, mumps, and rubella, talk with your doctor about getting vaccinated. If you’re unsure whether you’ve been vaccinated, you should first try to find your vaccination records. If you do not have written documentation of MMR vaccine, you should get vaccinated. The MMR vaccine is safe, and there is no harm in getting another dose if you may already be immune to measles, mumps, or rubella.
If you received a measles vaccine in the 1960s, you may not need to be revaccinated. 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.
