Researchers developing a vaccine against malaria have published results showing a high success rates so far. The scientists at an American biotech company irradiated mosquitoes to weaken the malaria causing parasites they carry. The enfeebled parasites were then injected into humans to trigger an immune response. Naomi Grimley reports.

That person might build up immunity, but it might take as many as a thousand bites to make that happen. Now an American biotech company in Maryland has built on that knowledge. Researchers irradiated mosquitoes extracted the malaria causing parasites and injected them into volunteers, 12 out of the 15 who'd been given the highest dose, then developed immunity.”
