The mask does not do anything, just read the data. The N-95 mask in ideal conditions does work to some extent. The American population wanted something to make them feel good about the Covid. So the Great Doctor changed his mind about the mask and everyone started wearing one.
I should have been more clear. It makes no difference to me if the vaccine works or not, we got them both, and it makes no difference to me what anyone says about wearing a mask, we're going to exercise personal choice and continue wearing them in public for a little while longer. What I'm not looking forward to are the angry Karen's and hillbilly Bob's that were once critical of those that wouldn't wear a mask, now turning their sights towards those who do... 😒
