Edward Jenner

About this figure

Edward Jenner (1749-1823) was an English physician who developed and popularized the world's first vaccine, providing protection against smallpox, one of history's most lethal infectious diseases. Trained in London under the surgeon John Hunter before returning to practice medicine in his native Gloucestershire, Jenner took seriously a piece of rural folk knowledge: that dairy workers who had caught cowpox, a mild disease transmitted from cattle, seemed to be protected from smallpox afterward. In 1796, he tested this idea directly, taking material from a cowpox lesion on the hand of a milkmaid, Sarah Nelmes, and inoculating an eight-year-old boy, James Phipps, with it. When Jenner later exposed the boy to smallpox matter, no disease developed.

He repeated similar trials over the following years and, in 1798, published his findings and reasoning in "An Inquiry into the Causes and Effects of the Variolae Vaccinae," coining the term "vaccine" from the Latin "vacca," or cow. The medical establishment received the idea with a mixture of interest and skepticism, and Jenner spent much of his later career defending and refining the practice against critics, but vaccination spread rapidly across Britain and then continental Europe within a few years of his publication, eventually reaching most of the world. Jenner received honors and, later in life, financial grants from Parliament in recognition of the vaccine's value, though he largely withdrew from London medical society to continue his rural practice. The method he pioneered, refined over the following two centuries, ultimately led to the global eradication of smallpox, declared by the World Health Organization in 1980, the only human disease eliminated in this way to date.
