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.

Glycerine was sometimes used simply as a diluent by some continental vaccine producers. However, Copeman found that vaccine suspended in 50% chemically-pure glycerine and stored under controlled conditions contained very few "extraneous" bacteria and produced satisfactory vaccinations. He later reported that glycerine killed the causative
