Face coverings are “the most powerful public health tool” the nation has against thecoronavirus and might even provide better protection against it than a vaccine, the head of the U.S. Centers for Disease Control and Prevention told lawmakers Wednesday.
“We have clear scientific evidence they work, and they are our best defense. I might even go so far as to say that this face mask is more guaranteed to protect me against Covid than when I take a Covid vaccine.”
CDC Director Dr. Robert Redfield said.
Redfield told the U.S. Senate Appropriations Subcommittee on Labor, Health and Human Services, Education, and Related Agencies that a potential coronavirus vaccine, which will likely be available in limited quantities by the end of this year, may only have an immunogenicity of 70%.
