Wow, I didn't know this. This is good information, @@. Our county will probably go back to masking and my Mom seems a little paranoid about Covid lately, like she wasn't at first but the longer it goes on the more paranoid she seems about it. I've been trying to explain to her that she's vaccinated and not doing really risky activities so the likelihood of her getting Covid is low. This explanation might help. Although I know with my own paranoia which has nothing to do with Covid, all the rational logical arguments of the world don't help because it's an emotional thing.
