Vaccine May Head Off Malaria’s Worst Effects

U.S. and Australian researchers may have found a new approach to vaccinating against malaria, which has so far been impossible to prevent with a shot. They developed a vaccine that works against a toxin produced by the malaria parasite, and said that while it didn’t protect mice against becoming infected, it prevented the deadly and more debilitating effects of infection.

If the approach works in further experiments, it might be a way to save some of the 2 million people, mostly children, who die of malaria every year, the researchers wrote in Thursday’s Nature.
