Rubella is a faint rash in a child but devastating in the unborn, causing Congenital Rubella Syndrome with deafness, blindness, and lifelong damage. An Australian eye doctor first connected the dots in 1941, and the 1964 to 1965 U.S. epidemic harmed some 20,000 babies. The vaccine aimed to protect the children of people who might catch it, and the U.S. declared rubella eliminated in 2004.
The epidemic figures are standard but approximate. Elimination is not eradication, since rubella remains endemic in parts of the world and U.S. cases are imported, and the epidemic's toll included many pregnancies ended for fear of severe damage.
