Biden Applauds Pfizers Ongoing Vaccine Development, Reminds Public To Keep Wearing A Mask 11/9/20, 8:40 a.m. ET
President-elect Joe Biden congratulated Pfizer on its ongoing development of a COVID-19 vaccine on Monday, while reminding the general public that widespread vaccination is likely still months away and that face masks remain essential in preventing the spread of the virus.
A mask remains a more potent weapon against the virus than the vaccine, he said in a statement that cited the Centers for Disease Control and Preventions past recommendation to wear a mask.
Pfizer announced on Monday that early data suggests that its vaccine candidate, which continues to undergo a clinical trial, is 90% effective at preventing COVID-19. As Biden said, however, that does not mean a vaccine for the coronavirus, which has killed more than 237,000 people in the United States, is imminent.
Americans will have to rely on masking, distancing, contact tracing, hand washing and other measures to keep themselves safe well into next year. Todays news is great news, but it doesnt change that fact, Biden said.

Pfizer Says Vaccine Is 90% Effective Against COVID-19 In Early Report 11/9/20, 6:50 a.m. ET
Pfizer released an early peek at data from its COVID-19 vaccine trials Monday and said its vaccine candidate was more than 90% effective at preventing COVID-19.
The interim analysis looked at 94 infections recorded among its around 44,000 vaccine trial participants in the U.S. and five other countries. Its unusual for a company to release such data so early.
The data shows that the company seems to be on track to requesting emergency use authorization from the FDA later this month.
Pfizer wont stop its trials until it records 164 infections among all volunteers, a number the FDA is enough to tell how the vaccine is working. The 90% initial rate could change as the study continues.
