Scientists in the UK have admitted they got things wrong in the early days of the coronavirus pandemic

According to British media reports, a number of scientists and experts admitted in interviews that they made mistakes in the early days of the global COVID-19 outbreak, including their understanding of the novel coronavirus vaccine, their opinion on whether masks should be worn and their prediction of the development trend of the Novel Coronavirus.Peter Openshaw, professor of experimental medicine at Imperial College London and an infectious disease expert, said he did not initially expect the coronavirus vaccine to be so successful.”To be honest, I didn’t believe the COVID-19 vaccine would work at first.Because until now, there have been no examples of vaccines for human coronaviruses, and vaccines for animal coronaviruses didn’t seem to work very well.”Peter said to him.However, he was surprised by the results of a trial at the end of 2020 on the effectiveness of the COVID-19 vaccine.”We mentioned the use of a vaccine in the first Novel Coronavirus report from the Faculty of Medicine, but at the time no one believed that an effective Novel Coronavirus vaccine would be available any time soon.So it was a shock to receive the first test reports on the efficacy of the Novel Coronavirus vaccine just before Christmas 2020.”Peter described the report as “the best Christmas present ever” because it showed that the Novel Coronavirus vaccine worked far better than he had predicted.In an interview with Foreign media, Peter said that as someone who has studied virus immunity for 30 years, he should have predicted that the vaccine would be useful in preventing novel Coronavirus, but regrettably underestimated its effect.”As a scientist, I’d love to see my views changed by scientific facts.I also pay tribute to the Oxford team for their remarkable contribution to the fight against COVID-19.”Professor Andrew Pollar, director of the Vaccine Unit at Oxford University, said he had not changed his mind about vaccinations, but said he had been misunderstood.”Some people think I’m against vaccinations, but I’ve never been against vaccinations.”I just think that the first and second doses of COVID-19 vaccine should take precedence over the third and fourth booster doses given that vaccine supplies are limited.”Andrew explained that more lives could be saved if existing vaccine doses were distributed more fairly around the world.”Given limited resources, I support giving priority to the first and second doses of COVID-19 vaccine to people who have not been vaccinated.That doesn’t mean I’m against people getting booster shots. I’m just more in favor of vaccine equity.”Susan Michie, professor of health psychology at University College London, said she had seriously underestimated the effectiveness of face masks in protecting against COVID-19.”In the early days of the global coronavirus outbreak, I do not think there is sufficient evidence that masks are effective in preventing novel coronavirus transmission, so I do not advocate wearing masks.”Susan said that initially she thought the Novel Coronavirus transmission was mainly through droplets, and that it could also happen if an infected person touches a mask and then touches other surfaces, so she did not think wearing a mask would be effective in preventing transmission of the virus.▲ In June 2020, German researchers found that effective mask wearing can reduce the rate of novel coronavirus transmission by up to 40%.Susan changed her mind, however, when she discovered that the main route of transmission in Novel Coronavirus is through aerosols.”The German study and other convincing evidence have changed my mind and I now believe that wearing masks is essential for preventing Novel coronavirus infections.”In June 2020, German researchers found that effective mask wearing can reduce the rate of novel coronavirus transmission by up to 40%.However, after Susan changed her views, she was subjected to months of taunts and attacks.”Someone asked me on a TV show, ‘How long do you need to wear masks?My answer is that people probably need to wear masks forever.”Before she could explain the next sentence, “It will depend on the environment and the risk of infection,” she was interrupted.She was bombarded with attacks and taunts on social media, with some even calling her a “dangerous lunatic”.”The scientific community continues to show that wearing a mask is really effective in preventing Novel coronavirus transmission,” she said.Neil Ferguson, an epidemiologist at Imperial College London who has seriously underestimated the rate of Novel coronavirus transmission and mutation, identified three things he said were wrong in an interview with British media.”First, we seriously underestimated the number of international visitors to the UK who were missed out in the early days of the global coronavirus outbreak.”According to Neil, he estimated that 70% of international tourists who entered China in February and March 2020 were not tested for COVID-19, but subsequent analysis showed that more than 90% of international tourists in that period were not tested for COVID-19 at the time of entry.It was only in March 2020, when hospitals in the UK began systematic testing, that we realised how serious the Novel Coronavirus outbreak had reached.”Second, we expected the Novel Coronavirus to mutate, but we did not expect the novel Coronavirus to mutate so quickly and so violently.”When the Novel Coronavirus variant Alpha first emerged, Neal explained, he was surprised by the speed of its spread and the extent of its evolution.”Thirdly, predicting the development of novel Coronavirus outbreaks has also become much more difficult than expected.”The first, Neal explains, is human uncertainty.As vaccination rates rise, people believe they have increased immunity and relax containment measures.This, combined with the emergence of a new variant of the Novel Coronavirus pandemic, makes the scientific community’s prediction of the future of the Novel Coronavirus outbreak less certain.”Although we can estimate transmissibility, severity, and vaccine effectiveness of a new variant within a few weeks of its emergence, there is a high degree of uncertainty in each assessment,” Neal explains.These uncertainties are multiplied in the prediction of future novel Coronavirus developments.”Red Star news reporter Fan Xu intern reporter Li Jinrui editor Guo Yu (download red Star news, the news has prizes!)
