Rapid antibody development yields possible treatment for yellow fever
Yellow fever, a hemorrhagic disease that is common in South America and sub-Saharan Africa, infects about 200,000 people per year and causes an estimated 30,000 deaths. While there is a vaccine for yellow fever, it can’t be given to some people because of the risk of side effects, and there are no approved treatments for the disease. An international team of researchers, led by MIT Professor Ram Sasisekharan, has now developed a potential treatment for yellow fever. Their drug, an engineered monoclonal antibody that targets the virus, has shown success in early-stage clinical trials in Singapore. This class of antibodies holds promise for treating a variety of infectious diseases, but it usually takes several years to develop and test them. The MIT-led researchers demonstrated that they could design, produce, and begin clinical trials of their antibody drug within seven months. Their approach, which condenses the timeline by performing many of the steps necessary...
