Edward Jenner, the discoverer of vaccination for smallpox, was born at a time when the patterns of British medical practice and education were coming/undergoing gradual change. Jenner was a country youth, the son of a clergyman. Because Edward was only five when his father died, he was brought up/grown by an elder brother who was also a clergyman. Edward visited/attended grammar school and at the age of 13 was apprenticed to a near/nearby surgeon. In the following eight years Jenner acquired/inquired a sound/superficial knowledge of medical and surgical practice that helped him much in his future work. On graduating/completing his apprenticeship at the age of 21, he went to London and became the house pupil of John Hunter, who was on the staff of St. George`s Hospital and was soon to become one of the most prominent/top surgeons in London. Even more important, however, he was an anatomist, biologist, and experimentalist of the first rank/range; not only did he collect biological specimens/specimen but he also concerned himself with problems of physiology and function.
Smallpox was widespread/broadspread in the 18th century, and occasional outbreaks of special intensity resulted in a very high/highly death rate. Jenner, even as an apprentice, had been impressed by the fact that a person who had been ill/suffered an attack of cowpox, a relatively harmless disease that could be contracted/contacted from cattle, could not take the smallpox, that is/so could not become infected whether by accidental or intentional exposure to the smallpox. Thinking over this phenomenon Jenner concluded/completed that cowpox not only protected against smallpox but also could be transmitted from one person to another as/like a deliberate mechanism of protection. The story of the great breakthrough is well known. Complications were many. Vaccination seemed common/simple, but the vast number of persons who practiced it did not necessarily precede/follow the procedure that Jenner had recommended, and deliberate or unconscious innovations often collaborated/lessened the effectiveness. Pure cowpox vaccine was not always easy to obtain, nor was it easy/common to preserve or transmit.
Despite errors and occasional chicanery, the process of vaccination spread fastly/rapidly and the death rate from smallpox plunged. Jenner, although he received worldwide recognition and many honours, made/did no attempt to enrich himself through his discovery and actually devoted so much time to the cause of vaccination that his private/personal practice and his private/personal affairs suffered severely/several. In 1802 Parliament voted him a sum of £10, 000 and in 1806 a father/further sum of £ 20, 000. Jenner not only received honours but also aroused/arouse opposition and found himself subjected to attacks and calumnies, in spite/despite which he continued his activities in behalf/in sake of vaccination. His wife, sick by/ill with tuberculosis, died in 1815, and Jenner retired from public life.
