I really wonder what options they think they have. There isn't a transplant program in the country that won't require full vaccination.
The article makes it seems like his refusal to vaccinate was the only thing keeping him from getting a transplant, but knowing how scarce donor hearts are, I suspect this is not the case. I doubt there was an available, properly matched donor. More than likely, he was never on the wait list to begin with. He probably needed full vaccination even before becoming eligible.
