PREVENTING INFECTION  An experimental vaccine against malaria has tested well in  early research. The  Anopheles mosquito, one shown here, spreads the parasite causing malaria.

The long, bumpy path to a malaria vaccine may have hit a smooth stretch as an early-stage study finds that multiple injections with inactivated malaria parasites can protect against the disease.

The findings are tantalizing but preliminary. The study was small, and the vaccine required five intravenously delivered doses to work, which would be an obstacle for teams attempting mass vaccination in developing countries. Also, the shots were tested in adults, not children, who are the prime victims of malaria.
