HIV may not have mutated so far but many viruses do in the end. When and if the HIV does and it probably will one day it could be even more deadly than it is now.
"probably" is too strong. "possibly" might do it, but even then, i'd doubt it.
viruses mutate for a variety of reasons, same as anything else. however, successful mutations - those which are passed on - are those which enable the organism to survive more easily or more efficiently - reproduce more quickly, or get into the host cell more efficeintly, as examples. there's little point in HIV mutating, as it's pretty well perfect for its job, at the moment. i'm not saying it won't, but there's no need for it to do so, from a biological point of view.
viruses are clever little things in the way they operate, which is why they're impossible to cure for them - there's no cure for the common cold, either, which is why it's so pointless taking medicines for it. vaccines aren't actually a cure, as such, as they are prophylactic.
oh, i'm on a roll - ask me about viruses - it's all flooding back to me...
