Selfishness is not a crime. In fact, to be blunt, in our society, it’s often treated as a positive attribute. Of course, we don’t call it “selfishness” - we call it “rugged individualism,” or “personal choice,” or whatever - but it’s all about elevating the individual, and individual rights, above any sense of obligation to one’s community, or to our society as a whole. What is “right for me” is defined as a higher priority than what is “right for all of us.” This is a choice we have made as a society. You can criticize it, or extol it - but regardless, it’s one of the things that makes us more vulnerable, as a society, to things like pandemics (and for that matter, to out-of-control gun violence, which is another situation in which we’ve elevated personal “rights” above the commen good). When people talk about “American exceptionalism,” this is part and parcel of what they’re talking about, although most won’t acknowledge that.
I agree with PC, actually, that we should not mandate an experimental, or “investigational” vaccine; it’s less clear that we should continue to not mandate that vaccine when it leaves investigational status. We require polio vaccines, we require measles, mumps, rubella, diphtheria, pertussis, tetanus - you can’t enroll in public school, or attend university, without these vaccinations. We used to require the smallpox vaccine, until WHO determined that smallpox had been eradicated in the wild. So, a vaccine mandate is nothing new or controversial (except with the true “anti-vax” people who have convinced themselves that vaccines, in general, cause autism, baldness, heebie-jeebies, etc., and with certain religious sects that believe… God knows what). It comes down to whether we see this disease as serious enough to require vaccination, or not. I would argue that any disease that has the potential to massively overload the nation’s emergency care capabilities, to the point that hospitals cannot accommodate other patients, should require vaccination, when a fully-approved vaccine is available. To refuse vaccination in such a situation is to invite other people to die, because you’ve overwhelmed our society’s ability to provide emergency care. There’s a point at which “selfish” becomes sociopathic.
