All your arguments are sound, and I'm still missing your point. Pharma is interested in doing pharma, indeed. But who's interested in your solution, assuming you have one? A significant part of the current electorate (internationally, even) seems to abhor sex ed, condoms, abortions and all that. So tell me again please how you suggest we address teen pregnancy - in THIS world.

The person I was responding to says "HIV is not a solved problem" and "we need a new tool to solve it, a vaccine!"

My argument is simply that new tools are great, but it's not what's going to solve the HIV problem. Distribution, cost, access, stigma, etc are the larger problems to deal with. (We need to solve all the reasons why people aren't using the existing tools)
