Are you serious? Most of Europe at least is at numbers that would've created herd immunity with the alpha variant (had the vaccine actually stopped transmission). I'd say that's pretty widespread.
I'm more referring to the fact that Europe is nowhere near the low end of the vaccination percentage health officials stated was necessary to have any chance at controlling this.
Ok, I think initial estimates (back in 2020) were that we'd need a vaccination rate of around 80-85% (which many countries have now). But that got thrown out of the window with force with Delta.
