Merozoite surface protein 1 (MSP-1(19)) is a leading malaria vaccine candidate. Specific antibodies contribute to immunity; binding to macrophages is believed to represent the main action of malaria antibodies. We show that an MSP-1(19)-specific immunoglobulin G3 (IgG3) monoclonal antibody can passively transfer protection to mice deficient in the alpha chain of Fc-gammaRI whose macrophages cannot bind IgG3.
