The most widely used vaccine against measles is the measles, mumps, and rubella (MMR) vaccine. The MMR vaccine provides protection against all three viruses: measles, mumps, and rubella. It is typically administered in two doses, with the first dose given to children between 12 to 15 months of age and the second dose given between 4 to 6 years of age.
In some cases, a measles monovalent vaccine may also be used, particularly in specific outbreak situations or in certain countries. However, the MMR combination vaccine is the most common option in many vaccination programs worldwide.
