From 1989 to 1991, a major resurgence occurred, affecting primarily unvaccinated preschoolers. This measles resurgence resulted in 55,000 cases and 130 deaths [17] and prompted the recommendation that a second dose of measles vaccine be given to preschoolers in a mass vaccination campaign that led to the effective elimination in the United States of endemic transmission of the measles virus.
