Heck, the previous strains were already too contagious. Anyway, it seems neither a covid vaccine, booster, or immunity from getting it before work very well in not catching covid. At least, they hopefully reduce the possibility of having to be hospitalized. I had what probably was covid in Feb. of 2020 and definitely had it in June of 2022 after being vaccinated but no booster. Both cases were fairly mild, didn't even go to the doctor over the first case, which didn't even occur to me at the time that it might be covid.
There is so much crazy crap that conspiracy theory nuts have been putting out against covid and covid vaccines that the government and media need to do something to debunk it. Ignoring it isn't the answer.
