1960: Before the discovery of a vaccine, most children in the United States had to endure a bout of measles; it was part of growing up. Many suffered nothing worse than three or four days in bed with a rash, a temperature and a cough, but complications and fatalities could and did occur.
Between 1912 and 1916 measles-related deaths averaged 5,300 a year – 26 deaths for every 1,000 reported cases. By the late 1950s the mortality rate had declined to less than one death for every 1,000 cases, but with an average of 542,000 cases of measles annually between 1956 and 1960, this still amounted to a significant number of deaths: 530 in 1956, 389 in 1957, 552 in 1958, 385 in 1959 and 380 in 1960.
