Diphtheria, the Strangling Angel of Children, caused over 200,000 U.S. cases and 15,000 deaths at its 1921 peak. It produced one of medicine's first lifesavers, the antitoxin, and one of its first disasters: in 1901 in St. Louis, antitoxin from a tetanus-infected horse named Jim killed thirteen children. That tragedy drove the 1902 Biologics Control Act, the first federal regulation of vaccines.
Credit for the antitoxin is shared beyond von Behring with Kitasato, Roux, and others. The St. Louis case is often called the first modern drug-safety disaster, a widely cited superlative, and the Nome run is heavily mythologized.
