This video catalogs the history of the vaccine for polio (poliomyelitis), a debilitating disease universally feared in the early twentieth century. The polio vaccine was developed in 1954 by Jonas Salk, following rounds of extensive testing. In April of 1955, after testing its effectiveness, Eli Lilly began production of the vaccine, strictly following safety protocols. Even today, a polio vaccination is a necessary precaution that effectively ensures the health of all children.
