A new monoclonal antibody discovered and developed at the National Institutes of Health safely prevented malaria for up to 9 months in people who were exposed to the malaria parasite. The small clinical trial is the first to show an antibody capable of preventing malaria in people. A total of 25 participants received at least one dose of an antibody named CIS43LS, and four of them received a second dose. Among adults who had never had malaria infection or vaccination, CIS43LS prevented malaria.
