One of the two Ebola-infected Dallas nurses was admitted to a National Institutes of Health biocontainment unit in Bethesda on Thursday, just as researchers at the University of Maryland School of Medicine in Baltimore are beginning the first human trials of an Ebola vaccine in Africa.
Dr. Myron Levine, a researcher at the medical school, is a member of the international medical group leading the efforts to end the outbreak. Ebola has infected more than 8,000 people since the first reported case in March, according to the Centers for Disease Control and Prevention.
