The Health Impact Fund: a potential solution to inequity in global drug access.

Global health inequities persist despite significant increases in funding and a growing number of global health initiatives. Especially vulnerable to disease, the poor majority of the world's population currently cannot afford advanced medicines, and the diseases confined to the poor receive little attention from pharmaceutical research. As a complement to the existing intellectual property regime, we have proposed the Health Impact Fund (HIF) as a mechanism that would create incentives for the development and optimal promotion of new high-impact medicines sold at the cost of manufacture. In this article, we outline the HIF and its ethical significance.
