LMIV conducts basic research in malaria immunology and pathogenesis, develops and produces prototype malaria vaccines, and conducts early-phase clinical trials of promising vaccine candidates. The lab's goal is to develop malaria vaccines that will reduce severe disease and death among African children and pregnant women and to eliminate malaria from low-transmission areas of the world.
Patrick Duffy, M.D., Laboratory Chief
LMVR studies disease-transmitting insects and broad areas of malaria biology and pathogenesis at locations on the National Institutes of Health campus and overseas. Basic discoveries support the development of new drug treatments, diagnostic tools, and vaccines. The LMVR environment is highly collaborative and is organized to foster research teamwork by experts in various disciplines of the biological, physical, and medical sciences.
Thomas E. Wellems, M.D., Ph.D., Laboratory Chief
