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. Fewster never made any claim to have discovered vaccination. John Fewster Dr John Fewster (1738–1824) was a surgeon and apothecary in Thornbury, Gloucestershire. Fewster, a friend and professional colleague of Edward Jenner, played an
Smallpox vaccine for further vaccinations. These were done and in 1798 Jenner published an analysis of 23 'cases' including several individuals who had resisted natural exposure after previous cowpox. It is not known how many Jenner vaccinated or challenged by inoculation with smallpox virus; e.g. Case 21 included 'several children and adults'. Crucially all of at least four who Jenner deliberately inoculated with smallpox virus resisted it. These included the first and last patients in a series of arm-to-arm transfers. He concluded that cowpox inoculation was a safe alternative to smallpox inoculation, but rashly claimed that the protective effect was lifelong. This
