Americans Await Final Approval of First COVID-19 Vaccine as Deaths Reach Record High VOA News The countdown has begun for the U.S. Food and Drug Administration's anticipated final approval of a coronavirus vaccine developed by U.S. pharmaceutical giant Pfizer and Germany's BioNTech, shown to be 95% effective in preventing COVID-19. The FDA is widely expected to authorize emergency use of the vaccine -- possibly later Friday or Saturday -- after a special panel of the agency voted for its approval Thursday. The decision came as the United States recorded a one-day record of deaths from the coronavirus, with more than 3,100 lives lost in a single day earlier this week. As of Thursday evening, the U.S. had recorded 15.5 million cases and more than 291,000 deaths, according to Johns Hopkins University data. Of the 22 people on the FDA panel, 17 voted in favor of authorizing the vaccine, four voted no and one abstained on the question: "Based on the totality of scientific evidence available, do the benefits of the Pfizer/BioNTech COVID-19 vaccine outweigh its risks for use in individuals 16 years of age and older?" The four panelists who dissented largely expressed concern about giving the vaccine to 16- and 17-year-olds. Teens younger than 18 were represented in small numbers in studies for the vaccine, and during the hours of deliberations, some scientists worried the effects on this age group weren't known well enough. The vaccine was approved after hours of deliberation on topics including allergic reactions to the vaccine recorded in Britain this week. The FDA panel's recommendation was hailed by President-elect Joe Biden. .
