> Globally, given an at-least-middle-class lifestyle (and any other years than 2020–2021), "not travelling outside [your home country]" is actually rather abnormal. It's mostly an American thing. Japanese people don't leave Japan much either. And between those two countries we've now called half the developed world "abnormal". It may be just as accurate to say Europe is the outlier, especially when you consider all of humanity and all of civilized history. Also it obviously depends where people travel to, developed or otherwise. Either way though, the vaccination recommendations in the US (as I'm sure every country) vary depending on whether you plan to travel or not. There isn't a fixed policy for everyone, at least when it comes to recommendations.
