Malaria Vaccine Found 67 Percent Effective in Human Trial
8th May 2015
A malaria vaccine was 67 percent protective against infection in an early-stage trial involving adults in Kenya, according to a study published in Science Translational Medicine today. The results are encouraging, as many malaria vaccines that work well in the lab have failed to show the same efficacy in the field. But low malaria infection rates in the region at the time of the study are putting a damper on the results.
