VACCINATION IS THE BEST PROTECTION!
All adults born in 1957 or later who have not been vaccinated or have not had measles should be vaccinated. Those vaccinated between 1963-1968 may have received a measles vaccine that was found to be less effective. If you are not sure whether you were vaccinated, it is safe to get another measles vaccine.
The only people who should not get measles vaccine are those who are immunocompromised or pregnant, or those who have had an allergic reaction to previous vaccine (rare, ~1 in a million). Talk with a trusted healthcare professional to find out if you should get vaccinated.
