Weir vaccination and lancet, cased, London, England, 1865-1875
Invented by Graham Weir, a doctor, sometime before 1866, this vaccination lancet was used for giving smallpox vaccines by scarification. This was a technique that broke the skin to introduce cowpox lymph material into the body. Cowpox is a milder form of smallpox and an attack of the former gives immunity to the latter. However, vaccination does not give life-long immunity. The four small blades were used to scratch the skin lightly in a cross-hatch pattern. The sharp pointed blade was used to collect the lymph material from a pustule of a person already vaccinated with cowpox. The blade was also used to apply the lymph material to cuts made in the skin of another person. The lancet with the tortoiseshell case would have been used in the same way.

After successful vaccination campaigns throughout the 1800s and 1900s, the World Health Organisation certified the eradication of smallpox in 1979. Smallpox is the only human infectious disease to have been completely wiped out.
