Medical Interventions under Investigation

A WHO background document lists seven experimental therapies and two vaccines under review. The therapies include ZMapp, made by Mapp Biopharmaceutical, which is a mixture of three monoclonal antibodies that are produced in tobacco plants. The drug has already been used in several patients and is thought to have contributed to the recovery of two American medical missionaries who contracted Ebola in Liberia. Other therapies listed include convalescent plasma, hyperimmune globulin prepared from the plasma of immunized animals or previously infected humans, interferons, and products made by Tekmira, Sarepta, Toyama Chemical/Fuji Film, and BioCryst. There are also two recombinant vaccines that have yielded promising results in animal experiments.
