It seems countries like this could benefit massively from an effective vaccine

I'm not sure why this is downvoted. Africa is the most affected continent of the HIV pandemic.

> Although the continent is home to about 15.2 percent of the world's population, more than two-thirds of the total infected worldwide – some 35 million people – were Africans, of whom 15 million have already died. Sub-Saharan Africa alone accounted for an estimated 69 percent of all people living with HIV and 70 percent of all AIDS deaths in 2011.
