Background and Date of Approval

The Measles, Mumps, and Rubella vaccine is a combination vaccine Measles, Mumps, and Rubella vaccine that protects against three infectious diseases: measles, mumps, and rubella. It is a routine childhood vaccination in many countries, including the United States. Measles is a highly contagious viral infection that can cause serious complications, including pneumonia, encephalitis (brain swelling), and even death. Mumps is a viral infection primarily affecting the salivary glands, causing swelling and pain in the jaw area. It can also lead to complications like meningitis (inflammation of the brain layer), deafness, and inflammation of the testicles or ovaries. Rubella is a viral infection that causes a rash and fever. While it is generally a mild illness, it can have severe consequences if contracted by pregnant women, as it can lead to congenital rubella syndrome in the unborn child. The U.S. Food and Drug Administration (FDA) first licensed the vaccine in the United States in 1971.
