"In theory, if China wants to achieve mass immunization, the vaccination rate needs to reach 83%. At present, China has vaccinated 1.15 billion people, accounting for 81.9%. I am full of confidence in achieving mass immunization by the end of this year.". In December 11th, the one of the "one belt, one road" International Scientific Organization Alliance launched the science forum of the Tai Wan District in Shangri-La, Guangzhou. At the life sciences sub forum held on the same day, Zhong Nanshan, winner of the medal of the Republic, academician of the Chinese Academy of engineering and famous respiratory expert, said in his speech < p > prediction: the national mass immunization can be realized by the end of the year < / P > < p > this Dawan District Science Forum takes "exploring the future and sharing science" as the theme and adopts the method of "online video + offline participation" to hold 1 high-standard plenary meeting, 6 sub Forums and 1 characteristic activity of Bay District Science and Innovation Summit. Focusing on the prediction and early warning of COVID-19 and other major public health emergencies in the future, the life sciences forum will invite representatives of leading scientists and biomedical companies at home and abroad, as well as biopharmaceutical companies, to explore the future development trend of world Life Sciences and offer suggestions for the development of life sciences in the Great Bay area of Guangdong, Hong Kong and Macau. At the Forum on Life Sciences, Zhong Nanshan, a member of the Republic medal, academician of China Academy of engineering and a famous respiratory expert, said that in early 2020, COVID-19 infected the world with 256 million people and 5 million 260 thousand people died in the world since COVID-19 began to wreak havoc around the world.

Under the guiding ideology of the supremacy of life in China, strict epidemic prevention has been carried out from top to bottom, and remarkable results have been achieved < p > when will mass immunization be available in China? Zhong Nanshan gave a time prediction. "In theory, if China wants to achieve mass immunization, the vaccination rate needs to reach 83%. At present, China has vaccinated 1.15 billion people, accounting for 81.9%. I am full of confidence in achieving mass immunization by the end of this year." < p > what is the effect of strengthening needle protection of domestic vaccine? Zhong Nanshan said, "from a large number of experiments abroad, the protective effect of domestic vaccine booster needle in the real world is 50% ~ 80%. At present, some laboratory data also found that the antibody produced by xenogeneic vaccine increased significantly, but the high antibody produced in the laboratory does not necessarily mean that it has strong defense ability in the real world." < p > drugs: China is also developing small molecule drugs for Xinguan < / P > < p > in terms of drug research and development for Xinguan, Zhong Nanshan introduced that the first domestic "Xinguan" specific drug brii-198 was officially approved by the State Food and Drug Administration recently, "This specific drug really solves many problems, which is the result of our joint efforts. In the future, we will develop small molecule drugs and traditional Chinese medicine. According to the characteristics of RNA virus, there are two main targets, one is the research on the structure of 3CL protease, and the other is the small molecule oral drug, which has a preventive and therapeutic effect of more than 80% on mild and moderate patients. The other is RdRp (RNA dependent RNA polymerase) -Nsp7-nsp8 complex ', which can only be put on the market after the third phase of research and development abroad. There are also several small molecule drugs under research and development in China. Another advantage is that traditional Chinese medicine has compound and unilateral prescriptions. At present, local research institutes and universities are stepping up the development and will soon be put into clinical use. " < / P > < p > in his speech, academician Zhong Nanshan also reviewed the development of Biosciences and expressed his compliments to scientists. "When I was in college in 1955, I saw two young people, a biologist and a physicist, who successfully discovered the double helix structure of DNA by means of X-ray diffraction, opening the era of molecular biology. This subversive discovery laid the foundation for the scientific development of genetic engineering, protein engineering and molecular biology in the 21st century. At the same time, it laid the foundation for the new crown to fight against epidemic and disease in the past two years Early intervention plays a role in promoting traditional Chinese medicine. "

fight against the epidemic: efforts need to be made between the disciplines and the state.

Zhong Nan Shan also said where COVID-19 came from, what is the middle host? How does aerosol define? How can aerosol be transmitted? Several problems remain to be studied. For COVID-19's fixed transmission rule, early pathological development after infection, and more precise treatment targets, etc. All interdisciplinary subjects of exhibition research should make joint efforts. "Whether it is virus traceability or vaccine research and development, there is an urgent need for joint efforts from all walks of life at home and abroad." < p > collected and written by: Nandu reporter Yang Liyun, Li Wen, Li Chunhua photography / video: Nandu reporter Chen Chong intern Li Muyun < / P > < p > < / P > < p >
