A large-scale Malaria vaccine trial at 11 sites in 7 African countries has shown significant success is stopping Malaria in children. This is a massive, huge, awesome breakthrough. The trial was funded by PATH and Gates and developed by GlaxoSmithKline (big pharmaceuticals doing something good?).
Anyway, yay! I look forward to reading and hearing more about this in the coming months and hopefully seeing a final vaccine that will stop some kids dying.
