usa has a real problem with this, afaik there is no way to get a duplicate/back up of your hard copy vaccination record. so i’m supposed to carry a piece of paper with me, and not lose it, i guess that’s what makes it a passport. meanwhile ime most places with vaccine requirement accept a photo on my cell phone - not exactly cryptographically signed stuff over here.
