【B1】______When they dry up, they leave ugly scars on the skin. For centuries it killed the rich and poor alike, spreading fast when it took hold in an area, and often seriously disfiguring or blinding those sufferers who escaped death. It was not until 1980 that the World Health Organization declared that the disease was eradicated, after the final recorded case in Somalia in 1977.
【B2】______It eventually offered reliable protection and caused smallpox to disappear completely. Jenner was bom in 1749 and, after studying medicine, lived and worked as a doctor in a small village, Berkeley, in rural Gloucestershire, England. There he saw people suffering both from smallpox and from cowpox, a weaker, much less dangerous form of infection, frequently found in
cows. He made the interesting observation that the local people who caught cowpox because of their daily contact with cattle did not catch smallpox, even if close friends and family were infected. By experimenting on local people, therefore, Edward Jenner was able to prove, in 1796, that injections of the cowpox virus could provide protection against smallpox. This process was called vaccination, from vacca, the Latin word for cow.
【B3】______The immunity he provided against one of history’s most terrifying diseases brought him fame and fortune. He was paid generous sums by the government when the authorities realized the importance of his achievement. He was also given the freedom of the City of London in 1805, an honour not lightly granted. He died in 1823.
【B4】______ By this time, vaccination had become a compulsory part of many countries’ public health programmes. It may seem surprising that Jenner’ s great discovery was not fully exploited at the time. This can be partly explained by the fact that complete eradication required a concerted effort from all countries.
【B5】______ The lives of millions of people have been saved by his careful observation and clinical work.
