The MMR vaccine helps prevent measles, mumps, and rubella. These diseases can cause serious illness, complications, or death. People born in the U.S. before 1957 are considered to be immune.

Who should get the MMR vaccine (if no evidence of immunity):

• People born in 1957 or later
• Women who are not pregnant, but could become pregnant; rubella could cause miscarriage or serious birth defects
• International travelers, close contacts of people with weakened immune systems, and college students
• Health care workers

Who should not get the MMR vaccine

• Pregnant women
• People with a weakened immune system
• People with HIV infection and a CD4 count under 200
