Are you willing to get the Covid vaccine when offered?

I honestly cannot comprehend him not taking the vaccine to get a transplanted heart. I like to look at both sides and usually pretty understanding from both sides but this one I have trouble with. If you are willing to subject yourself rightfully so to stay alive with a new heart, why wouldn't you take the vaccine, when you are about to take a butt load of drugs that will affect you so your body accepts the new heart and will probably be taking a butt load for the rest of your life that will affect you. I get he probably has a principal but darn dude.
