Robert Redfield, director of the Centers for Disease Control and Prevention, said that they have a clear scientific evidence that masks work and are more guaranteed against COVID.
“We have a clear scientific evidence they work,In fact, this face mask is more guaranteed in protecting me against COVID than when I take up a COVID vaccine. This is 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 told a Senate committee, reports Bloomberg.
He further added that masks are “the most important, powerful public health tool we have.”
