Prevention of Mumps:

Mumps vaccine (usually MMR), is the best way to prevent mumps. Other things people can do to prevent mumps and other infections is to wash hands well and often with soap, and to teach children to wash their hands too. Eating utensils should not be shared, and surfaces that are frequently touched (toys, doorknobs, tables, counters, etc) should also be regularly cleaned with soap and water, or with cleaning wipes.

Mumps Vaccine:

Two doses of mumps-containing vaccine, given as combination measles, mumps, rubella (MMR) vaccine, separated by at least 28 days, are routinely recommended for all children. The first dose is given on or after the first birthday; the second is given at 4 - 6 years of age.  MMR is a live, weakened (attenuated) vaccine. Most adults who have not been vaccinated should also receive 1 dose of MMR vaccine, but adults who work in healthcare, a school/university setting, and persons at high risk of exposure to mumps should get 2 doses.  Pregnant women and persons with an impaired immune system should not receive live attenuated vaccines (MMR vaccine).
