Mmr Vaccine

What is the MMR vaccine?

The MMR vaccine is an injection given to help prevent M easles, M umps, and R ubella. These are common childhood infections caused by 3 different viruses.

  • Measles: The measles virus, also known as rubeola, causes a skin rash to appear on the head and upper neck. The rash slowly spreads to the hands and feet. Measles can lead to ear infections, pneumonia, seizures, and brain damage.

  • Mumps: The mumps virus infects many parts of the body and usually causes inflammation of the parotid glands. These glands make saliva and are found in the cheeks. Mumps can lead to hearing problems, meningitis (swelling of the brain covering), or orchitis (swelling of the testicles).

  • Rubella: Rubella, also called German measles, causes a skin rash that usually starts on the face. The rash spreads to the chest, abdomen, back, arms, and legs. A pregnant woman who gets rubella could have a miscarriage or her baby could be born with serious birth defects.

Who should get the MMR vaccine?

  • Infants 6 to 11 months: Only infants traveling internationally should receive 1 MMR shot. They should then follow the same schedule as children 12 months to 6 years.

  • Children 12 months to 6 years: Children usually receive 2 MMR shots. The first dose should be given at 12 to 15 months. The second dose is usually given at 4 to 6 years. The second dose may be given before age 4 if it has been at least 4 weeks since the first dose.

  • Children 7 to 18 years: Children and adolescents who have not had the vaccine should receive 2 doses. Those who have had only had 1 dose should receive a second dose at least 4 weeks after the first dose.

  • Adults:

    • Adults born before 1957: Adults born before 1957 are considered immune and do not need the MMR vaccine unless they work in healthcare.

    • Adults born during or after 1957: Adults born during or after 1957 may need 1 or more doses.

    • Adults born during or after 1957 who are at high risk: A second dose may be given to people at higher risk for measles, mumps, or rubella. The second dose is usually given 4 weeks after the first dose. The following people may have a higher risk of infection:

      • College students

      • Healthcare workers

      • Anyone who has recently been near someone with measles, mumps, or rubella

      • Anyone who plans to travel to a different country
