Women born after 1957 may need measles booster

With confirmed U.S. cases of measles at a

25-year high, doctors at the Children’s Hospital of Philadelphia and Vanderbilt University in Nashville are now advising people born between 1957 and 1968 to make sure they received a measles shot, and all women born between 1957 and 1989 to consider a booster. Why? The vaccine was introduced in 1963 and improved to 90% efficacy in 1968. The booster, which increases levels of protection to 97%, was implemented in 1989. Women born before 1957 are presumed immune due to exposure to the then-common disease.
