The vaccine reserved for you did not go to the third world instead.
Once a vial is opened the vaccines contained therein can’t be shipped overseas and will expire in a few hours. I could therefore wait outside a Walgreens before closing and get the shot.
Except Im not a utilitarian. I cannot take what is rightfully another’s just because they cant enjoy it. I believe that all young people should have refused the shot, therefore liberating millions of doses. Mine is but the first (literal) drop in what should be an ocean; and Im actively encouraging my friends to do the moral thing and refuse to get boosted.
I don't know where to draw the line myself, so I wonder what kind of rules you set for yourself. This sounds like one of the most extreme examples I've heard.
