Re: masking. Covid is a more dangerous virus than the flu or common cold, but at the molecular level it is the same size, regardless of the "variant." Therefore, a virologist should already know if masks work or don't. If you follow Fauci's emails/pronouncements, he first said masks are useless. Then, they were necessary, then two masks. Then you don't need one if vaccinated. Now we're back to masks. If you've spent your professional life studying viruses, you shouldn't be jumping all over on this. I'd like to follow the science but when "experts" don't know their science...
