An experimental Ebola vaccine will soon enter phase one of a clinical trial on humans, the National Institute of Health said Thursday. Initial testing will take place at the NIH’s Clinical Center in Bethesda, Maryland, while the NIH is in the process of working out tests in Ebola-stricken West Africa. The vaccine was developed by the National Institute of Allergy and Infectious Diseases (NIAID) along with top pharmaceutical company GlaxoSmithKline.
