On September 16 local time, U.S. President trump and the director of the Centers for Disease Control and prevention, Redfield, once again disagreed on the issue of vaccines and masks. Robert Redfield, director of the U.S. Centers for Disease Control and prevention, said on the same day that the vaccine may be ready as early as November or December this year, but the first dose is very limited and may be used for the most vulnerable groups, while full supply to the public will wait until the end of the second quarter or the third quarter of 2021. However, trump believes that Redfield’s timeline is wrong. On the same day, trump refuted Redfield at a press conference, saying that he was wrong or wrong. When he talked to Redfield, he did not say so. Trump said the vaccine would start distribution as early as sometime in October, and once the time was set, it would begin. Trump has repeatedly said that he is confident to launch the vaccine by the end of this year, but the process of accelerating the launch of the vaccine is facing public doubts. An associated press poll in May showed that only about half of Americans said they would be vaccinated. The vast majority of those who don’t get vaccinated say they are worried about safety. At the same time, Redfield also said that wearing masks may be more effective than vaccination, and masks are the most important and effective anti epidemic tool. In Trump’s view, this view is also wrong. “No, masks are not as important as vaccines. Maybe masks work, but don’t forget that many people didn’t like the concept at first. ” At present, the CDC has not responded to the president’s remarks. According to data from Johns Hopkins University, there are more than 6.629 million confirmed cases and more than 196000 deaths in the United States.
