From the article: "One important limitation to a T-cell vaccine
targeting HIV itself is that HIV exists in so many variations and is
constantly mutating."

Even this piece of the HIV Bible is disputed by some members of the
HIV medical killing squad.  I raised this point with my HIV doctor. He
told me that resistance due to HIV mutation wasn't a problem: he said
he had patients who had remained on the same 'treatment' for years.
His thinking was that once he had found a personal treatment planned
that 'worked,' the patient would stay on it indefinitely.

I believe 'worked' in this case is defined as producing the fewest
side effects.

I think all this nonsense about HIV mutating is just a smokescreen to
cover up the fact that it cannot be found.  Presumably when sales of
HIV drugs start to fall, because they've achieved their aim of killing
those 'infected,' an HIV wonder vaccine will suddenly be discovered.
