I think you are a little off on what constitutes the carrot approach. Being an outcast of normal society until you get a vaccine sounds rather stick-ish to me.
Eta: oh, I see you’re in China. I guess if you’re not in an organ donor prison camp, it’s all carrots.
Here in Italy healthcare workers must be vaccinated. If they refuse, they are offered office jobs if possible. If not, they will lose their employment.
I’m not convinced vaccine passports are a good idea in all cases, but for healthcare this seems totally reasonable.
The same rules that would cause (some) Amish (and possibly Mennonites) to refuse vaccination would also prevent them from working what we would call “frontline jobs”: The purpose is to prevent, as much as possible, interaction between the Amish community and “the English” (everyone else). And when you follow a rule like that (literally) religiously, it really does do a lot to prevent disease spread: It’s like the social distancing and “podding” that we’ve all been encouraged to do for the past year, except that they’re experienced at it (they don’t need to leave their community to buy groceries, for instance).
While there are some legitimate comments to be made about human rights issues in China, this is just a cheap stereotype and is more of a pot-shot than anything else. These types of comments are not appropriate in this forum. Please do not do this again.
