Pfizer released trial results for a vaccine

On 9 November 2020, Pfizer released their trial results for a candidate vaccine, showing that it is 90% effective against the virus. Later that day, Novavax entered an FDA Fast Track application for their vaccine. The 9 November announcement does not mean the vaccine is about to be released. However, virologist and U.S. National Institute of Allergy and Infectious Diseases director Dr. Anthony Fauci indicated that the Pfizer vaccine targets the spike protein used to infect cells by the virus. Some issues left to be answered are how long the vaccine offers protection, and if it offers the same level of protection to all ages. Initial doses will likely go to healthcare workers on the front lines.
