During tests of a new malaria vaccine, intravenous delivery and use of radiation-weakened parasites proved effective at preventing the disease in small groups of adults. Scientists irradiated billions of malaria parasites in lab-raised mosquitos and used them to create the vaccine. The promising results encourage further efforts to test the vaccine’s long-term protection and develop accessible delivery options for malaria hotspots in remote areas.
