In an interview with The Washington Post, Carswell said he recently applied for a kidney transplant but was turned down because he has not received a coronavirus vaccine. And, despite his hospital's requirements that organ recipients be vaccinated against the virus, he's refusing the shots.

Carswell, of Hickory, N.C., acknowledged his condition is a "ticking time bomb," and said he's living every day as though it's his last. Still, he will not take a coronavirus vaccine — even if that means losing out on a potentially lifesaving transplant.

"There is not a situation in this world that I'll get a vaccine," he told The Post. "If I'm laying on my deathbed, and they tell me, 'You have a kidney waiting on you if you get this shot,' I'll tell them, 'I'll see you on the other side.'"
