Currently, there are ongoing measles outbreaks in the United States. The risk of measles remains low for most of the United States due to high immunization coverage and rapid case identification and response efforts. Measles-mumps-rubella (MMR) vaccination is the best way to protect against measles and its complications.
Measles was declared eliminated in the United States in 2000. This was thanks to a very high percentage of people receiving the safe and effective measles, mumps, and rubella (MMR) vaccine. In recent years, however:
- U.S. MMR coverage among kindergarteners is now below the 95% coverage target—much lower in some communities—and is decreasing.
- Global measles activity is increasing, meaning more chances of an unvaccinated person infected with measles abroad returning to the United States.
