We haven't heard much about that kind of chatter here, but I've seen some talk of it online and while I don't think the majority of people will fall for the same gag twice there was a vocal minority who had quite the hard on for lock downs and virtue signalling, be it just to feel good or because it benefitted them financially so there will always be someone saying its for grandma when its actually for some other ambition

I hope im wrong but apart from China I don't see people taking kindly to it again, be it for sickness or climate maybe CBDCs could drive it though, when theres direct payment/compensation involved you can get the majority to do just about anything
