Definition
John Fewster (1738 – 1824) was an English surgeon and physician noted for his early observations linking cowpox infection with immunity to smallpox, observations that preceded and influenced Edward Jenner’s development of the smallpox vaccine.
Overview
Born in 1738 in the county of Somerset, England, Fewster pursued medical training and established a practice as a surgeon‑physician. In the late 18th century, he became interested in the relationship between cowpox and smallpox after noting that a patient who had contracted cowpox did not develop smallpox subsequently. In 1796, Fewster delivered a lecture to the Bath Medical Society outlining his observations and suggesting the potential for deliberate inoculation with cowpox to prevent smallpox. Although he did not develop a systematic vaccination program, his notes and advocacy are regarded as a contributory influence on Edward Jenner, who, later that same year, carried out the first successful smallpox vaccination experiment. Fewster continued to practice medicine until his death in 1824.
