The measles vaccine was first introduced in the United States in 1963. Before 1989, federal guidelines recommended only one dose of the measles vaccine, so people vaccinated before the guidelines changed generally do not have the coverage thatâs now advised.
Before the measles vaccine was introduced in the 1960s, many children came down with the disease by age 15. About 3 million to 4 million people got measles each year in the United States. Among them, about 500 people a year died, and 4,000 developed encephalitis, or brain swelling.efore the measles vaccine was introduced in the 1960s, many children came down with the disease by age 15.
