Grandpa Tang Wan, formerly known as Gu, is the former president of Peking Union Medical College, a famous physician and virologist. 20 1910.2, Gu died in Beijing at the age of 92. Mr. Gu devoted his life to fighting polio, commonly known as "polio", which is an acute viral infectious disease of children. He is one of the pioneers of China tissue culture oral live vaccine, and a small sugar pill has become the memory of generations of China people. In 1950s, a disease was very popular in China. That's polio, commonly known as polio. It may cause different degrees of paralysis, and the most serious thing is that you can't breathe spontaneously. Once you get sick, there is no cure. When Gu was in danger, a vaccine was developed after a lot of animal experiments. Gu Zhoufang and his colleagues first experimented with their own bodies. However, polio often occurs in children under 7 years old and must be tested in children. Gu Kailai's eldest son became the first child in China to drink this vaccine. Gu: Our first child was born in 1960, June 4th, 1960. Later, we thought that he just met this requirement. He is less than one year old. We are in this business and don't believe in ourselves. How can people believe in themselves? The vaccine production base was completed in 9 months. After three clinical trials, the vaccine was successfully developed. However, there are more than100000 newborns born in China every year, plus hundreds of millions of children under 7 years old. To produce so many vaccines and ensure their safety, this important task was once again given to Gu. Gu came to Kunming with his mother, wife and son, and established the Institute of Medical Biology of Chinese Academy of Medical Sciences in Huahong Cave, Jade Case Mountain, which is dozens of kilometers away from Kunming. At that time, Yu 'an Mountain was deserted, with no roads, water and electricity, so researchers built houses with big stones on their shoulders. It took only nine months to build a vaccine production base for all children in China. Gu Liedong, the eldest son of Gu: The children of our Institute of Biology go to school together with the children of Yi people, and the conditions are also very difficult. Although there are classrooms in the school house, the windows are broken, and there is no heating equipment in winter. We took a washbasin ourselves, pierced a hole, burned charcoal and put it under the desk to keep warm. Gu Zhoufang lived in a ravine in Yunnan with his mother, wife and three children for seven years. During this period, he and other colleagues successfully developed live attenuated sugar pills. Since then, the average annual incidence of polio in China has dropped significantly, saving hundreds of thousands of disabled children. From June 5438 to October 2000 10, the World Health Organization confirmed that the spread of wild poliovirus in China was blocked and it became a polio-free country. Wang Chen, vice president of China Academy of Engineering and president of China Academy of Medical Sciences: Mr. Gu Zhoufang's contribution should be said to be historic. He is the inventor and provider of the most important scientific and technological means to control and eradicate polio in China, and also one of the most important promoters of this great historical process (polio eradication in China). Gu: I just hope that our burden can be handed over to young people. I wish the national immunization workers take good care of every child, protect every child and let them grow up healthily.
