For well over a thousand years，smallpox was a disease that everyone feared. The disease killed

century. By the end of the eighteenth century，smallpox was responsible for about one in ten deaths around the world. Those who survived the disease were left with ugly scars on their skin.

It had long been well known among farmers that people who worked with cows seldom caught smallpox;instead,they often caught a similar but much milder disease called cowpox(牛痘) .A British doctor called Jenner was extremely interested in this，and so he studied cowpox. He believed that,by vaccinating (接种疫苗) people with the disease, he could protect them against the much worse disease smallpox. In 1796，he vaccinated a boy with cowpox and,two months later,with smallpox. The boy did not get smallpox. In the next two years, Jenner vaccinated several children in the same way，and none of them got the disease.

News of the success of Jenner' s work soon spread. Vaccination soon became a common method to protect people against other diseases caused by virus，such as rabies(狂犬病) ，and vaccines were sent across the world to the United States and India.

It took nearly two centuries to achieve Jenner ，s dream of getting free of smallpox from the

whole world. In 1967, the world Health Organization (WHO ) started a great vaccination program， and the last known case of smallpox was recorded in Somalia in 1977. The story of vaccinations does not end there, however. There are many other diseases that kill more and more people every year. Besides,many new diseases are being discovered. The challenge for medical researchers will,therefore，probably continue for several more centuries.
