In need for a altruist pharma company?

I talked to Jenn yesterday about AIDS and the quest for a cure/vaccine. I was wondering if there was any truly altruistic pharmacetical company in the world who would be willing to invest billions of dollars into this project. The reason was that if they develop the cure, I don't think they are going to get much returns in terms of profit as this would be free medication where it's needed the most. In a capitalist world economy like we have now, it makes no business sense to work on it if the governments don't offer compensation for the R&D. It's hard for me to imagine that we aren't closer to a cure if it wasn't a money issue. Drug companies keep making innovations in fields that have huge scope for profits but not for those which would give near zero return. I might research a little more into this to see how much of progress has been made in this front.
