Gates: it is unlikely to be more contagious after the Omicron variant

Share with friends and circles of friends with wechat scanning QR code on January 12, US local time on Tuesday, Microsoft co-founder Bill Gates and Devi Sridhar, Professor of global health and director of global health governance program at the University of Edinburgh, jointly participated in the Q & A activity on twitter. They talked about novel coronavirus pneumonia vaccines, including the shortcomings of the new crown vaccine and the trend of disease development. Novel coronavirus pneumonia vaccine has two major defects in p>

's 45 minute conversation, Gates said. It is unable to prevent repeated infection caused by virus variants and to protect the duration of the vaccine. "Novel coronavirus pneumonia is unlikely to be more susceptible to spread after the" variant "virus. We should expect that the new crown pneumonia is much less infected. For the rest of the year, the virus can be treated like seasonal flu Gates also talked about several familiar topics in the past two years, including the mistakes made in dealing with the epidemic, the opportunity to obtain vaccines, and defended his conspiracy theory about taking the opportunity to implant chips into the human body. Gates said he didn't expect himself and Dr. Tony Fauci, an infectious disease expert, to be the object of this false information campaign. He asked, "some things, such as when I implant a chip into the human body, are meaningless to me. Why should I do this?" the following is Gates's Q & a session: Q: now, what scientific or technological breakthroughs will have a greater impact on ending the epidemic Gates: our existing vaccines can well prevent severe infection and death, but they have at least two key defects: these vaccines still can not prevent variant virus infection, and the duration of protection seems to be very limited. We need vaccines that can prevent repeated infections and last for many years Q: I absolutely agree with you that the next generation vaccine should have the ability of eliminating immunity. Second question: what challenges are still facing in popularizing global vaccination Gates: during 2021, the supply of vaccines will be greatly limited, and most of them will flow to rich countries. Now we have a lot of supply on the whole, and the problem turns to logistics and demand. In addition, health systems in developing countries are a limiting factor. MRNA vaccine still can't meet all the needs, so it's still quite complicated to find out who injected what vaccine Q: there are many discussions about Pfizer, Moderna and other pharmaceutical companies' responsibility for vaccine supply. What role do these companies play in ensuring pricing and supply, especially in low - and middle-income countries Gates: when we have enough supply, we will use the hierarchical pricing strategy. At that time, the cost paid by rich countries is much higher than that of middle-income countries, while the cost paid by low-income countries is the least. When supply is limited, rich countries cannot bid higher than other countries, so the government remains the key Q: given that you have been warning against respiratory infectious diseases for many years, looking back from 2020 to 2021, what do you think is the biggest mistake made by most countries (with resources) in dealing with the epidemic Gates: several countries like Australia have taken rapid action to screen infection cases on a large scale and isolate infected people, which can greatly reduce the number of deaths. Once the number of infections in a country surges, it may be too late to take action. Therefore, the response in the first few months is crucial. In addition, some countries have done better in reducing mobility, using masks and protecting older persons. But we were not prepared and did not practice in advance. Do you think the world will unite to prepare for the next similar crisis? I hope so, but I'm not sure Q: a question of great concern is the online error information about vaccines, masks and other interventions on Facebook and other platforms. How should we deal with this challenge? Especially when expertise is ignored and conspiracy theories are spread as if they were facts Gates: trusted institutions such as the World Health Organization (who) and the Centers for Disease Control and prevention need more resources to detect the epidemic situation early (monitor) and communicate better. Social media is lagging behind in trying to publish factual information, and there will be a lot of debate on how to do better in this regard. People like you, me and Dr. Tony forge are affected by a lot of misinformation. I didn't expect this. Some things, such as rumors that I took the opportunity to implant a chip into the human body, are meaningless to me. Why should I do that Q: speaking of the mission of the Gates Foundation, what do you think is the biggest challenge facing the development of poor countries? Have we regressed in terms of girls' education and child survival Gates: from 2000 until the outbreak of the epidemic, we have made great progress in health and other goals. But the epidemic is a huge setback, including that rich countries do not pay enough attention to the needs of developing countries. I hope we can turn this around. I am optimistic about polio eradication. We are very close to our goal. It will take much longer to eradicate malaria, HIV, and strengthen nutrition, but better tools are coming. Education also needs innovation, which lags behind the field of global health, especially girls' education Q: here is another thorny question: where do you think sars-cov-2 came from? What data do you want to view? Is this information important to prevent future outbreaks

Gates: the data are awesome enough to indicate that it comes from other species, which is correct for most epidemics. People will continue to study this, and we should ensure the caution of the laboratory. There will be outbreaks from other species in the future, so we need to invest and be prepared Q: the last question, maybe everyone wants to know the answer, that is, how and when will the epidemic end? Does Omicron indicate that we will "coexist with the virus"? Or will there be other dangerous virus variants in 2022 Gates: as countries experience the epidemic of Omicron variant virus, their health system will be challenged. Most severely infected people will be unvaccinated. Once the outbreak caused by Omicron virus is over, fewer infections should be seen in the rest of this yearThis novel coronavirus pneumonia can be treated more seasonally than influenza. p> more transmissible variants are unlikely to occur, but Omicron surprised us during this epidemic. At least next year, Omicron will make more people immune to the virus. In the future, we may be vaccinated every year. Trevor Bedford, an associate professor of epidemiology at Washington State University, started a dialogue on how to avoid the next epidemic, which is very important. I appreciate his work in this regard. We can do better next time! (small)
