Instruction leaflet for dried smallpox vaccine B.P. (Ovine), single dose of Lancy-Vaxina for use with scratch technique, by Swiss Serum and Vaccine Institute for Department of Health and Social Security, (DHSS), 1980
The strain of virus used for this vaccine was grown and gathered from the skin of a sheep infected with smallpox. The vaccine was then administered through the skin by a scratch technique. This smallpox vaccine was created for the Department of Health and Social Security (DHSS) in London. Smallpox vaccination programmes led to the global eradication of the disease in 1979.
