CDC director Robert Redfield suggested in a Senate Appropriations subcommittee hearing on Wednesday that face masks are "more guaranteed" to protect against the coronavirus than a vaccine, citing the potential for some people to not become immune to the virus after receiving the shot.
What he's saying: "These face masks are the most important, powerful public health tool we have. And I will continue to appeal for all Americans, all individuals in our country, to embrace these face coverings. I've said if we did it for 6, 8, 10, 12 weeks, we'd bring this pandemic under control," he said.
The big picture:While face masks are one of the best COVID-19 mitigation strategies we currently have, a vaccine remains the best long-term solution. A number of coronavirus vaccines are now in phase 3 trials, including candidates from Oxford and Moderna that produced immune responses in tests this summer.
What to watch:Redfield told the subcommittee that he believes there will be a "very limited supply" of a vaccine between November and December, and that "we're probably looking at late second quarter, third quarter of 2021" for widespread distribution.
