The Departments of Health, Human Services and Defense hold a briefing on the Trump administration's Operation Warp Speed coronavirus vaccination program on Wednesday after Pfizer released positive data on its Covid-19 vaccine.
Earlier in the day, Pfizer announced that a final data analysis found its coronavirus vaccine with BioNTech was 95% effective against Covid-19, was safe, and appeared to ward off serious illness. The company plans to file an emergency claim with the Food and Drug Administration "within a few days."
Pfizer announced on July 22 that the US had agreed to purchase 100 million doses of its vaccine for up to $ 1.95 billion. The agreement, which is part of Operation Warp Speed, allows the US to purchase an additional 500 million doses of vaccine.
