Well, actually, HIV/AIDS has been one of Big Pharma's BIGGEST successes. They have turned this into a chronic disease rather than one that kills in 6 months.
Not much of a success.
They have succeeded in convincing this insanely promiscuous group that they can now go out and engage in their deadly behavior at record levels.
And the virulence of the HIV is not in check. They can still infect (and do.)
So we've got even more folks with this "chronic disease."
