Canada and the Development of the Polio Vaccine

During the first half of the 20th century, poliomyelitis, a.k.a. polio or “The Crippler,” hit Canada harder than anywhere else. Successive polio epidemics peaked in a national crisis in 1953. By that time, however, scientists at Connaught Medical Research Laboratories of the University of Toronto had made key discoveries that enabled American medical researcher and virologist Jonas Salk to prepare the first polio vaccine.

Canada went on to play an important role in the development of the oral polio vaccine and international efforts to eradicate the disease.
