Pharmaceuticals have greatly improved health in developing countries, but many people in developing countries do not obtain even inexpensive pharmaceuticals and little pharmaceutical R&D is oriented toward products needed by developing countries, such as a malaria vaccine. Access to existing products could be improved by facilitating differential pricing, for example by subsidizing donation programs, and reforming health care delivery. R&D incentives could be improved if rich countries or international organization committed to purchase needed products when they are developed and make them available to the poor.
