It seems to me that a Kryptonite vaccine would only make sense if he had an immune system that fought a Kryptonite germ. It also would make sense if it were like ingesting a small enough dosage of a Kryptonite poison until he built up a resistance. However, I don't understand the mechanics behind a vaccine to ward off radiation, unless of course they were simply counting on an unintelligent audience or were writing with an unintelligent staff.
I also find it convenient that Kryptonite is available to every Joe schmoe on the street who asks for it. Whatever happened to the laws of supply and demand?
