Delaware health officials report a measles outbreak in the state. 23 confirmed cases have been reported, all from Kent County.
These are the first positive measles cases in more than a decade.
The best way to protect against measles is with the measles, mumps, and rubella (MMR) vaccine. MMR is safe and effective – serious reactions are extremely rare. Two doses of MMR vaccine are about 97% effective at preventing measles; one dose is about 93% effective.
