Mmr Vaccine


What is the MMR vaccine?

The MMR vaccine is an injection given to help prevent measles, mumps, and rubella. Measles causes a skin rash to appear on the head and upper neck. The rash slowly spreads to the hands and feet. Mumps infects many parts of the body and usually causes inflammation of the parotid glands. These glands make saliva and are found in the cheeks. Rubella causes a skin rash that usually starts on the face. The rash spreads to the chest, abdomen, back, arms, and legs.

Who should get the MMR vaccine?

  • Infants 6 to 11 months traveling internationally may need 1 MMR shot. They should then follow the same schedule as children 12 months to 6 years.
  • Children 12 months to 6 years 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 who have not had the vaccine should receive 2 doses. Those who have had only 1 dose should receive a second dose at least 4 weeks after the first dose.
  • 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 may need 1 or more doses. Adults born during or after 1957 who are at high risk may need a second dose. This dose is usually given 4 weeks after the first dose. The following adults may have a higher risk for infection:
    • College students
    • Healthcare workers
    • Anyone who has recently been near someone with measles, mumps, or rubella
