Africa's always going to be a problem. Assuming this vaccine is effective, we need to take the same approach to HIV that we did to smallpox. That will likely mean substantial Western subsidies for poorer nations, and a concerted boots-on-the-ground effort to administer the vaccine. It will be a long time before HIV is eliminated, and it will come at a substantial cost to taxpayers, but it's well worth it to rid ourselves of this disease.

It will also mean knocking the people who are convinced the vaccines cause AIDS out of the political world, lest they destroy our ability to do that. This will require action in both the Western world and in Africa, and will make a number of people very unhappy.
I know most people here don't care about those morons. However, any accounting of the cost has to include the political cost.
