Have you had your measles shot? How to know if you need the measles vaccine or booster
If you were born 1967-1991: The measles vaccination program started in 1963, according to the CDC. The vaccine was made better by 1967 and the first dose was routinely recommended starting that year, while the second dose — also known as the booster shot — was routinely recommended in 1991, Offit said.

“If you received one dose, you have about a 90 percent chance of being protected. Which is to say, if you were born between 1967 and 1991, you have a 90 percent chance of being protected,” he noted.

“If you were born after 1991 and have received both doses, you have about a 97 percent chance of being protected.”
