Lancets, late 18th-early 19th century.

These lancets belonged to Edward Jenner (1749-1823). In 1796 Edward Jenner (1749-1823) used a lancet to introduce fluid from a cowpox sore through a person's skin, in order to inoculate them against smallpox, a similar but more dangerous disease. He called his method "vaccination", from "vacca", the Latin word for cow.
