The Hulk's healing ability is, as far as I can tell, the strongest of any Marvel character to date. While it is extremely difficult to injure him in the first place, if it does occur any injury regardless of severity heals almost instantly. It's also been shown that the Hulk has some resistance to mystical energies, but could it overcome something like Vampirism, or Lycanthropy? His healing factor has a (vaguely) scientific explanation of a constant regeneration of his cells fueled by his Gamma rage, but it is often shown in comics that science can be trumped by magic (i.e. Superman's weakness to magical forces) Given that it would be nearly impossible for a regular vampire to even bite the Hulk even in a base, non-enraged state. I would think it possible for say Dracula or Lilith, or any of the top tier vamps to, given the right circumstances, bite and infect the Hulk. Has anything like this ever been shown before?
I am aware that the Hulk from the Marvel Zombies universe was infected, but I believe that was more of a scientific reason for the plague; I'm looking for a supernatural based ailment.
