China news agency, Washington, February 12 (Reporter Chen Mengtong) "Put on a mask, America. Put on the mask. " US President Biden said at the National Institutes of Health on the 11th.

　　Biden made a speech after inspecting the vaccine research center of the institute on the same day. While announcing that the vaccine supply sufficient to cover the entire American population will be put in place ahead of schedule, he once again stressed that the epidemic situation in the United States is still grim, reminding the American people not to take it lightly.

　　Biden announced that the US government had signed a final contract with two pharmaceutical companies, Moderna and Pfizer, that afternoon, and the total 200 million doses of COVID-19 vaccine it purchased would be delivered in batches before the end of July. This means that the supply of vaccines in the United States will reach 600 million doses by then, "faster than expected."

　　Biden further stated that universal vaccination is only the bottom line, and the ultimate goal of the United States is to defeat Covid-19. "This brings us another challenge."

　　Biden wore a mask all the time during the speech. He said, "This is a very important message", "In the next year, wearing a mask can save lives — — A considerable number of lives. "

　　According to Johns Hopkins University data, as of 23: 00 on the 11th, the number of COVID-19 infections in the United States has exceeded 27.39 million, with 475,000 deaths.

　　Biden pointed out that in January 2021, the United States experienced the "deadliest" month of the epidemic — — Lost 100,000 lives. In the United States, the death toll may exceed 500,000 in March, and at the same time, it faces the threat of mutating Covid-19.

　　According to the data of the US Centers for Disease Control and Prevention, as of the 11th, the number of people who received at least one dose of vaccine in the United States was 34.72 million, and the average daily dose in the past week was 1.61 million doses.

　　The Hill pointed out that although former President Trump ordered 400 million doses of vaccine during his tenure, it did not solve the "last mile" problem of vaccine distribution and vaccination. The shortage of vaccine supply that plagues the United States will continue at least in the short term.

　　"Frankly speaking, my predecessor was not ready to vaccinate hundreds of millions of Americans. He didn’t order enough vaccines and didn’t mobilize enough manpower to complete the vaccination work. " Biden said that when he took office, the United States did not have a large-scale vaccination plan, "it was a mess."

　　"We are still in danger of Covid-19 pandemic," Biden stressed. "Wearing a mask is still the easiest way to save lives, but we need everyone to wear a mask."
