How do vaccines reduce the spread of measles?
Quick Answer
Measles vaccines prevent infection in most people and stop the virus from moving through communities. High coverage is needed because measles spreads very easily.
The Full Story
Measles is one of the most contagious human diseases, so it requires exceptionally high vaccination coverage to prevent outbreaks. The measles vaccine is usually given as part of the MMR combination vaccine, which also protects against mumps and rubella. Two doses provide strong protection for most people, and widespread vaccination has dramatically reduced measles deaths worldwide. However, outbreaks can still occur when vaccination rates fall or when the virus is imported into undervaccinated communities. Because measles can cause pneumonia, encephalitis, and immune suppression, preventing spread is crucial.
