FDA Chief Scientist Denise Hinton told Pfizer in a letter Friday that she was authorizing the emergency use
of the company’s vaccine.
The FDA’s emergency use authorization will now kick-tart the federal government’s distribution
of the potentially lifesaving doses to 64 states, territories and major cities across the nation.
The government plans to distribute 2.9 million doses of the vaccine within 24 hours,
followed by an additional 2.9 million doses 21 days later for patients to get their second shot.
