Academician Chen Wei's team has made important achievements in the development of new crown vaccine
According to CCTV news broadcast on March 3rd evening, the scientific research team led by academician Chen Wei of the Academy of military medicine has been working hard to fight on emergency research and achieving important achievements in the development of novel coronavirus vaccine.
In the video, Chen Wei said, "President Xi pointed out that vaccines, as a special product for the wellbeing of people, are essential for epidemic prevention and control. We must keep the leader's instructions in mind and strive to push the recombinant new crown vaccine we are developing to the clinic and application in the shortest time, to provide strong scientific and technological support for winning the prevention and control of the epidemic. "
Chen Wei is a female scientist who has made important contributions to many hard battles such as the fight against SARS and Ebola. She was promoted to the rank of major general in July 2015 and elected as an academician of the Chinese Academy of Engineering in November 2019. The novel coronavirus vaccine is also the "seed athlete" in the running of the new type of coronavirus vaccine.
On January 26 this year, on the second day of the lunar new year, major general Chen Wei, 54, led the expert group to Wuhan. A novel coronavirus nucleic acid detection kit (RT-PCR fluorescent probe) developed by the Military Medical Research Institute and local companies 2 days later (January 28th) was registered by the State Administration of drug supervision for emergency examination and approval. Four days later (January 30), the tent type mobile detection laboratory of the Academy of Military Sciences started to operate. With the application of self-developed detection kits and the full-automatic extraction technology of nucleic acid, the detection time of nucleic acid was greatly shorter than the existing time, which accelerated the speed of diagnosis.
China's most recent novel coronavirus pneumonia is the most popular issue in the January issue of Chen Wei, which is worth mentioning. Novel coronavirus pneumonia is being developed at top speed by the government's support, Chen Wei said.
"But there are inherent cycles and rules in vaccine research and development. However, our understanding of the biological characteristics, pathogenic mechanism, transmission mechanism, susceptible population, etc. of this new virus is still very superficial. Therefore, it is unrealistic for us to get the vaccine within one month as soon as reported on some platforms." "Of course, I can't rule out that a very good research team can do better and faster," Chen said at the time
"On January 28, President trump announced that U.S. scientists will develop a new crown vaccine within 12 weeks, and I believe that our national researchers will not be slower than the United States," Chen said
The novel coronavirus mutation is fast and is also in the category of coronavirus. At present, big data research is developing rapidly. Once new mutation occurs, it is possible to find common target antigens, pathogenesis or receptors through bioinformatics or big data mining, and can quickly guide the improvement of vaccines. Chen Wei said.
