A friend of mine had a kidney transplant this past summer. She was required to be vaccinated against covid (already had it). She also had to lose a significant amount of weight and pass several tests for blood pressure and other medical risks. They told her that they needed to ensure that whoever received a donor kidney would survive long enough to make it worth “spending” the kidney on, since they are in such short supply. That makes sense to me.<p>If she had been a smoker who refused to stop, could not lose the weight, or not taken measures like getting the vaccine, she would have been considered unqualified.
