Nature: Share the risks of Ebola vaccine development
Seth Berkley, chief executive of Gavi, the Vaccine Alliance

“…Vaccine development is driven not by the risk that a pathogen poses to people, but by the economic pay-off. … That helps to explain why, more than a year on from the first confirmed cases of the ongoing Ebola outbreak in West Africa, no vaccine is available, even though work started towards one more than a decade ago. … Governments and donors need to invest in public health capability, and they need to take on more of the risk of investing in vaccine development. We must view vaccines as the ultimate deterrent: make sure they are there, and pray that we never have to use them” (3/18).
