Five years ago, Bill Gates made an extraordinary offer: he invited the world’s scientists to submit ideas for tackling the biggest problems in global health, including the lack of vaccines for AIDS and malaria, the fact that most vaccines must be kept refrigerated and be delivered by needles, the fact that many tropical crops like cassavas and bananas had little nutrition, and so on.
No idea was too radical, he said.
Now the five years are up, and the foundation recently brought all the scientists to Seattle to assess the results and decide who will get further funding.
In an interview, Mr. Gates said, “We were naïve when we began.” He underestimated, he said, how long it takes to get a new product from the lab to clinical trials to low-cost manufacturing to acceptance in third-world countries.
Over all, he said: “On drawing attention to ways that lives might be saved through scientific advances, I’d give us an A. But I thought some would be saving lives by now, and it’ll be more like in 10 years from now.”
