John Fewster (1738 – 3 April 1824)^[1] was a surgeon and apothecary in Thornbury, Gloucestershire. Fewster, a friend and professional colleague of Edward Jenner, played an important role in the discovery of the smallpox vaccine. In 1768 Fewster realized that prior infection with cowpox rendered a person immune to smallpox.^[2]^[3]

Fewster was educated at Bristol Grammar School before a seven-year apprenticeship at the Bristol Infirmary.^[4]

Development of the smallpox vaccine

In 1768, Fewster noted that two brothers (named Creed) had both been variolated (purposefully infected with smallpox) but that one did not react at all to variolation. On questioning, this subject had never had smallpox, but had previously contracted cowpox. This prompted Fewster to wonder whether cowpox might protect against smallpox, a notion of which he was previously unaware. He is reported to have discussed this possibility over a Convivio-Medical Society dinner at the Ship Inn in Alveston. He also encouraged others to take up the inquiry. Amongst those at the meeting was Edward Jenner, a young medical apprentice at the time.^[5]^[6]

Fewster followed up this observation, but only to a limited extent and not in writing.

In 1796, Fewster was called to visit a local boy who was ill with early smallpox and was asked by John Player, the boy’s uncle, whether he would consider inoculating the boy with cowpox to save him from smallpox. According to Player Fewster replied that he had already thought of this but had decided against it as, in his view, variolation was very successful and an alternative seemed unnecessary. Nonetheless, Player reports, Fewster went on to inoculate three children in Thornbury with cowpox, during spring 1796. These vaccinations took place at around the same time as Jenner's first vaccination attempts.^[5]

Fewster never made any claim to have discovered vaccination.^[7]

Many sources claim that in 1765, Fewster read a paper to the Medical Society of London titled "Cow pox and its ability to prevent smallpox". However, the Medical Society of London was created in 1773. See:

Furthermore, the earliest insinuation that Fewster had written a paper titled "Cow pox and its ability to prevent smallpox" appeared in 1886. See:

By Fewster's own account ((Pearson, 1798), p. 102), he merely " … communicated this fact [that prior infection with cowpox provides immunity to smallpox] to a society, of which I was then a member, … ". He made no mention of having written a paper on the subject.
