U.S. Centers for Disease Control and Prevention Director Robert Redfield told a Senate panel on Wednesday that face masks are better at protecting against the coronavirus disease than a potential vaccine.
During a hearing on the federal response to COVID-19 (coronavirus disease) hosted by the Senate Appropriations Subcommittee on Health and Human Services, Dr. Redfield testified:
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 because the immunogenicity [ability to provoke an immune response] may be 70 percent. And if I don’t get an immune response, the vaccine is not going to protect me. This face mask will.
The director of the CDC, a component of the U.S. Department of Health and Human Services (HHS), failed to cite any data to support his mask claim.
