by Edward Jenner
Introductory Note
Edward Jenner was born at his father’s vicarage at Berkeley, Gloucestershire, England, on May 17, 1749. After leaving school, he was apprenticed2 to a local surgeon, and in 1770 he went to London and became a resident pupil under the great surgeon and anatomist, John Hunter, with whom he remained on intimate terms for the rest of Hunter’s life. In 1773 he took up practise at Berkeley, where, except for numerous visits to London, he spent the rest of his life. He died of apoplexy on January 26, 1823.
Jenner’s scientific interests were varied3, but the importance of his work in vaccination has overshadowed his other results. Early in his career he had begun to observe the phenomena4 of cowpox, a disease common in the rural parts of the western counties of England, and he was familiar with the belief, current among the peasantry, that a person who had suffered from the cowpox could not take smallpox5. Finally, in 1796, he made his first experiment in vaccination, inoculating6 a boy of eight with cowpox, and, after his recovery, with smallpox; with the result that the boy did not take the latter disease.
Jenner’s first paper on his discovery was never printed; but in 1798 appeared the first of the following treatises7. Its reception by the medical profession was highly discouraging; but progress began when Cline, the surgeon of St. Thomas’s Hospital, used the treatment with success. Jenner continued his investigations8, publishing his results from time to time, and gradually gaining recognition; though opposition9 to his theory and practise was at first vehement10, and has never entirely11 disappeared. In 1802, Parliament voted him 10,000 pounds, and in 1806, 20,000 pounds, in recognition of the value of his services, and the sacrifices they had entailed12. As early as 1807, Bavaria made vaccination compulsory13; and since that date most of the European governments have officially encouraged or compelled the practise; and smallpox has ceased to be the almost universal scourge14 it was before Jenner’s discovery.
