My wife's nephew is 30 and just bought a bar in small town Wisconsin within the past year.
He did not get the vaccine because, he reasoned, he's young and healthy, so he had nothing to worry about. The vaccine is for old people, like—well, me and my wife. So he's been working six days a week in his bar, no mask on him, no mask on anyone. Everything was fine.
Earlier this month, he contracted COVID. Laid him out pretty good. He was home for ten days while recovering. He's back at the bar now, but he still doesn't have any smell or taste.
He's getting the vaccine now, because it happened to him.
Multiply this by a few million.
