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.
In 1997, the year before the paper was published, measles vaccination rates in the United Kingdom were over 91%. They started to fall in 1998 and in 2003-2004 reached a nadir of just 80%, although rates were even lower than that in specific areas.
