“For the next several days, Hoffman and the other volunteers bit their nails and hoped the vaccine would keep them healthy. (Those who come down with the disease are given drugs to kill the parasites.) By day ten, three volunteers were sick, but Hoffman and two others felt fine. Excitement began to swell; no injected malaria vaccine had come close to 50-percent protection—and this was its very first trial. ‘We thought we were going to win the Nobel Prize,’ Hoffman says.”
