I re-read my comment, and I realized how impersonal it was. Of course, there is a science-first way of thinking of things and then there are practicalities of being with family. I just traveled from the US to Eastern Europe and back for a family emergency. I spent two weeks with my elderly mother deciding it was OK to potentially expose her based on on a three-day-old COVID test. (There really was no other choice, and luckily all turned out well.) Maybe, even with vaccines, it's all about managing risk to the best of our abilities and dealing with the unknowns.
