Mice were protected against lethal Plasmodium yoelii malaria by vaccination with a Triton X-100 lysate of whole parasitized erythrocytes. For full effectiveness this vaccine required an adjuvant, and we have found that recombinant gamma-interferon has strong adjuvanticity in this model when given either intraperitoneally or subcutaneously. Specific immune responses that were enhanced included antibody, T cell help, and delayed hypersensitivity.
