Interesting. I know some places require yellow fever but think that’s the only one commonly required. Seems common for South America. I think a world cruise be fun if ever rich enough so sounds like would need to get it. Personally not a fan of vaccines for multiple reasons, but I got a feeling at some places if you just wanted only what was required they’d try to convince or guilt you into getting the others. Maybe though if knowing you are going to go on a trip where you need it, get it elsewhere... say you go vacation in Europe, probably cheap enough to self pay even without being covered by their insurance. Plus the ingredients can vary by country too. I guess the one approved for Canada and the one approved for the US are different yellow fever wise.
