My overall take on masks is they might reduce your chances of getting it by 5-10% is you wear it around a contagious person, if they wore one it probably goes up to 20% or so. The original vaccine data were over 90%, so this isn't all that impressive of course until you run exponents.
At this point, I'm not wearing a mask unless forced, or knew I was close to a contagious source for a few minutes.
Obviously I was very close to my wife for days after she was positive and didn't get it, I wasn't wearing a mask. My GUESS is the booster worked for me and not for her.
One of her symptoms was sneezing more than usual, which obviously is a spreading event. I didn't really notice it. She said she had some fever off and on, but we were walking 4-5-6 miles a day during the period, she wasn't complaining. Her case obviously was on the mild side, which is great, and she likely has more resistance now than I do to the new types. I MIGHT have sparked my immune system to the new type, I don't know.
We've discussed many times the importance of hospitalizations in all the numbers, we're way down now, and I expect to stay that way.
