Zhang Wenhong: Accelerate the speed of vaccine research and development and increase confidence in controlling the epidemic |
China News Service, Beijing, November 16. Zhang Wenhong, Director of the Department of Infectious Diseases, Huashan Hospital, Fudan University, Shanghai, noted that the current rapid development of vaccines indicates that human science and technology are constantly developing. Therefore, it is very strong in controlling the new corona epidemic. trust. He also reminded that attention should be paid to the new coronavirus.
Zhang Wenhong recently accepted an exclusive interview with the Chinese news agency “Focus on China” in Beijing.
Speaking of vaccine research and development issues of public interest, Zhang Wenhong said that after a new infectious disease arises, vaccine research and development is developed under emergency conditions, and the speed will accelerate. And development has accelerated this time.difficultHistorically, it has been an accelerated and regular R&D process, but now the technical force is better than before, so the R&D speed will be faster. This shows that human science and technology are constantly developing, and it will only get faster and more accurate at unimaginable speed. “It is precisely because of this that I have great confidence that the new corona epidemic will eventually be brought under control.”
Zhang Wenhong predicts that by the end of this year or early next, the world will basically start vaccinating related vaccines.
Speaking of people’s perception that “the number of asymptomatic infections is increasing and the number of deaths does not seem to be that many,” Zhang Wenhong said that the rate of increase in the number of cases is not consistent with the rate of increase in deaths, that is, The fatality rate of new patients has decreased worldwide; there is also a data called weekly fatality rate, which has also decreased. This can give everyone the illusion that the virus is not as poisonous as it used to be.
He pointed out that the model for calculating the fatality rate is the key to the problem. Diagnostic capabilities have vastly improved around the world. Many asymptomatic people will be tested and many asymptomatic infections will be found. In the initial stage, the diagnostic capacity cannot cover asymptomatic people, so the early onset of the disease is severe and the mortality rate is naturally higher. Now that asymptomatic people are also being tested, the death rate will be very low. “This is normal because the same group of people is not being selected.”
Second, on a global scale, the population with the highest mortality rate is the elderly. This high-risk group has begun to protect itself. The case fatality rate for young people is inherently low. The global epidemic is characterized by (mainly) young people infected after the restart of society, but their fatality rate is low.
Third, from January to the present, new crown rescue supplies around the world have been continuously replenished. Preventing and controlling the epidemic means fighting. The better the logistical support, the more successful the battle will be and the higher the success rate of patient rescue.
Zhang Wenhong also pointed out that it is often wrong to guess the cause of a phenomenon at will. For example, now that the death rate has dropped, but if you are not in the medical system, it is easy to think that the virus is not as powerful as before.
Therefore, Zhang Wenhong stressed that we must still pay attention to the virus.
