In Lutheran Sweden, the Protestant clergy played a pioneering role in voluntary smallpox vaccination as early as 1800. The first vaccination was carried out in Liechtenstein in 1801, and from 1812 it was mandatory to vaccinate.The question of who first tried cowpox inoculation/vaccination cannot be answered with certainty. Most, but still limited, information is available for Benjamin Jesty, Peter Plett and John Fewster. In 1774 Jesty, a farmer of Yetminster in Dorset, observing that the two milkmaids living with his family were immune to smallpox, inoculated his family with cowpox to protect them from smallpox. He attracted a certain amount of local criticism and ridicule at the time then interest waned. Attention was later drawn to Jesty, and he was brought to London in 1802 by critics jealous of Jenners prominence at a time when he was applying to Parliament for financial reward. During 1790–92 Peter Plett, a teacher from Holstein, reported limited results of cowpox inoculation to the Medical Faculty of the University of Kiel. However, the Faculty favoured variolation and took no action. John Fewster, a surgeon friend of Jenners from nearby Thornbury, discussed the possibility of cowpox inoculation at meetings as early as 1765. He may have done some cowpox inoculations in 1796 at about the same time that Jenner vaccinated Phipps. However, Fewster, who had a flourishing variolation practice, may have considered this option but used smallpox instead.
Terminology
The word "vaccine" is derived from Variolae vaccinae (i.e. smallpox of the cow), the term devised by Jenner to denote cowpox and used in the long title of his An enquiry into the causes and effects of Variolae vaccinae, known by the name of cow pox. Vaccination, the term which soon replaced cowpox inoculation and vaccine inoculation, was first used in print by Jenners friend, Richard Dunning in 1800. Initially, the terms vaccine/vaccination referred only to smallpox, but in 1881 Louis Pasteur proposed at the 7th International Congress of Medicine that to honour Jenner the terms be widened to cover the new protective inoculations being introduced. According to some sources the term was first introduced by Jenners friend Richard Dunning in 1800. References
