Bill Gates's World of Possibility: "Melinda Moree met plenty of naysayers who dismissed the prospects of a malaria vaccine. Then she encountered Bill Gates.
No one had developed a human vaccine against a parasite like malaria before, and the monetary incentives simply did not exist for pharmaceutical companies to develop drugs targeted at poor children. Development would require cooperation among scientists, drug companies, health groups and international governments -- an alliance so large it didn't seem possible, she recalled someone telling Gates."
