That's not going to last long, though. If (and I think it's a long shot) more than a handful of governments start to reimpose mask mandates, your kid (to use your story) is going to have to get tons more sticks because there's going to be a whole lot of poking going on. And some of the people getting that treatment aren't going to accept it.
Businesses didn't want to enforce mask mandates in the first place, even when there was no vaccine. There's no way they're going to do it if the bosses and employees are all vaccinated. And at least in Illinois, any type of police or agency enforcement against businesses was few and far between even in the worst days of COVID. If this turns into a serious problem, vaccine passports may be the only answer - preferable at the national level. Let's hope more people take the hit and get vaccinated.
