The only way to prevent measles is by receiving measles immunization: This is commonly given as a shot containing measles, mumps, and rubella vaccine (MMR) or a shot containing measles, mumps, rubella, and varicella vaccine (MMRV). The MMRV is not recommended for anyone older than 12 years of age. The current recommendation is that everyone receives two doses of the vaccine after 1 year of age. If the vaccine is received before 1 year of age, the person should receive two additional doses.
The measles vaccine is also available as a single vaccine; however, in most cases, there is no reason to utilize the measles vaccine alone without mumps and rubella vaccine. The complete schedule of recommended vaccinations is available from the CDC (http://www.cdc.gov/vaccines/recs/schedules/child-schedule.htm).
