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.
The measles outbreak in the U.S., which includes most of the 102 cases in 14 states between Jan. 1 and Jan. 30 this year, likely did originate from outside this country. Whether it came from an immigrant living in the U.S. illegally, however, is unknown.
