I agree in theory with that, but maybe from a different perspective. People who have been vaccinated are not seeing symptoms nearly as severe as others, and may likely be causing spread without knowing.I'll tell you right now, people who are not getting the wackzine are also not getting tested so there's no clear data to prove that they are the ones causing this "variant".
Long story short: Turn off your televisions and live a happy life.
One of my brewshop employees was vaccinated... Not sure which one (none of my business)... And popped for covid a couple weeks ago ago. He said it was kind of like a mild cold for a couple of days, but we kept him away until he had a negative test. This was further complicated by my back up guy, who did note get a vaccine ("I'm strong and healthy, why should I be afraid of it") and had covid at the the same time. He was basically in bed for 2 weeks and now weeks later he says he gets exhausted just going up the stairs. For what little it's worth, he wishes he would have gotten a the vaccine. Obviously a small sample size... And we've known for a long time covid impacts people differently, but still interesting how someone's tune can change when they actually have to deal with it.
What I find interesting is how so many of the trump drum beaters still take the hard line on the "wackzine", even though their demagogue helped develop it pretty publicly took it himself. I personally think the way he pushed the development of the vaccine was one of several really positive things Trump did while in office.
... Wait... He's still in office though. Silly me, I always forget my truths!
