What are the ethics, though, of refusing to get a vaccine? if Alex Honnold had fallen off the face of El Capitan, he would have killed only himself. Is it not the same in the case of someone refusing to be vaccinated, given that the vaccination is available to everyone who does want it?
There is one difference, I suppose. The person who refuses vaccination and subsequently gets a serious case of COVID-19 causes society to spend a good deal of money treating them in the hospital. (Even if they have insurance they are needlessly increasing the costs of care for everyone.)
