Around 700 years ago, real life human beings devoloped a natural immunity to "The Black Plague".
This same mutation, subsequently gives their decendants immunity to the HIV/AIDS viruses of nowadays. [This evolutionary weapon humans have devoloped is designated "CCR5-Delta 32"].... Not kidding..
So if actual human beings can be immune to HIV/AIDS, then I see no reason why Wolvie couldn't beat it. ermm
