Doctor Scott Podolsky, associate professor of Global Health and Social Medicine at Harvard Medical School, has written in the Annals of Internal Medicine, that ZMapp (an experimental drug that had previously only been tested on monkeys and given to two American missionaires with the Ebola virus) has much in common with methods of treating illness that were being developed toward the end of the 19th century. In Medical News Today, James McIntosh recounts Dr. Podolsky's article.
