Are you willing to get the Covid vaccine when offered?

You asked me what concerns I would have for the son in law and then imagined how I would feel, so I may have read that wrong, as you were putting me in the place of the relative who missed out on the transplant.

But for me, if all things were equal, my decision wouldn't be based on a vaccine that wouldn't work as efficiently as in someone healthy and ineffective against Omicron without booster. Regardless of their vaccine status, they will more than likely be in the upper right hand quadrant for severe symptoms and death and will be recommended to do everything possible to avoid COVID because in his condition, there is only hope that the vaccine will do what it needs to, but with his current state of health, future health state, and Omicron running lose, good luck with that.

But let's say that he takes the shot, get's COVID and still die, then what? Or what if he get's the vaccine and dies from adverse effects? He died doing "the right thing?"

Nobody dies from adverse effects of the covid vaccine.

And, you're on a crusade obviously to try to convince yourself and the rest of us that un-vaxed people are unfairly being discriminated against.

I find that to be a silly notion. First, discrimination against those who refuse medical advice while appealing to medical advisers is not unfair. Second, treating people who make difficult decisions differently is completely reasonable. I don't force vegans to eat wagyu when they come to my house and that's very reasonable. Finally, for this post, if the decision making board comes to the conclusion that there is a better candidate based on their criteria and the anti-vax clown is left out in the cold then all of us are better off even if the other guy who received it dies.

You are confusing principle with opinion. If he's prepared to die due to his opinion that vaccines are dangerous or whatever then he has to live or die with that decision. Nobody is forcing him to refuse medical advice.
