  1. Is there a vaccine to prevent mumps?

    Yes. Two doses of mumps containing vaccine usually, given as a combination measles, mumps, and rubella (MMR) vaccine, separated by at least 28 days, are routinely recommended for children. Most adults who have not been immunized should also receive one dose of MMR vaccine. Adults who work in healthcare, schools, or those at high risk of exposure to mumps should receive two doses. There is also a vaccine that protects only against mumps .

    The mumps vaccine currently used was licensed in 1967.

    The mumps vaccine is a live attenuated (weakened) virus. It is recommended that mumps vaccine be given as part of the MMR vaccine (protecting against measles, mumps, and rubella).

  2. Who should get this vaccine?

    Mumps vaccine is recommended for all U.S. children and for susceptible adolescents and adults without documented evidence of immunity.

    The Centers for Disease Control and Prevention (CDC), the American Academy of Pediatrics (AAP), and the American Academy of Family Physicians (AAFP) have all recommended this vaccine.

  3. What side effects have been reported with this vaccine?

    Fever is the most common reaction, occurring in 5%-15% of vaccine recipients. About 5% of persons develop a mild rash. About 25% of adult women receiving MMR vaccine develop temporary joint symptoms such as pain, redness, or swelling. More severe reactions, including allergic reactions, are rare.

    Mumps is a very safe vaccine. Most side effects are mild and related to the measles or rubella components of the MMR vaccine (fever, rash, temporary joint symptoms).

  4. How effective is this vaccine?
    Approximately 80% of individuals become immune to mumps after a single dose of vaccine. The second dose of MMR results in 90% of people immunized being immune to mumps.
