Today, and even after we have a vaccine, C.D.C. encourages all Americans to embrace the powerful tools that we have right now — to wear a mask, particularly when they’re in public, maintain social distancing, routine vigilant handwashing. Be smart about crowds, and stay home when you’re sick. We’re going to continue to give Congress and the nation the best public health advice. We’re not going to let political influence try to modulate that. Face mask — 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 it, if we did it for six, eight, 10, 12 weeks, we’d bring this pandemic under control. These actually, 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 the Covid vaccine because the immunogenicity 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.
