Although measles was eliminated in the U.S., cases and outbreaks are happening around the country, mostly in unvaccinated people and communities. Measles spreads easily through the air and can cause serious illness, but it’s preventable with the MMR vaccine, which offers 97% protection after 2 doses.

Don’t wait, make sure you and your loved ones are up to date on your MMR vaccine. Schedule your vaccine appointment at MyTurn.ca.gov or with your health care provider.
