Former CDC director criticizes new study that raises doubt about wearing masks | TheHill - The Hill

A former director of the Centers for Disease Control and Prevention (CDC) lambasted a study from Denmark released on Wednesday that concluded that surgical masks do not protect against the coronavirus.

A surgical mask is better than most cloth masks.

"We have clear scientific evidence they work, 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 may be 70 percent and if I don't get an immune response, the vaccine's not going to protect me, this face mask will," Redfield said
