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. Connaught Labs also solved the problem of producing the vaccine on a large scale. Canada went on to play an important role in the development of the oral polio vaccine and international efforts to eradicate the disease.

SARS in Canada

Smallpox in Canada

Smallpox is an infectious disease caused by the variola virus. The disease arrived in what is now Canada with French settlers in the early 17th century. Indigenous people had no immunity to smallpox, resulting in devastating infection and death rates. In 1768, arm-to-arm inoculation became more widely practised in North America. By 1800, advances in vaccination helped control the spread of smallpox. Public health efforts also reduced rates of infection. In the 20th century, Canadian scientists helped the World Health Organization eradicate smallpox. Eradication was achieved in 1979, but virus stocks still exist for research and safety reasons.
