(CNN) The first human trial of an experimental Ebola vaccine has produced promising results, U.S. scientists said, raising hopes that protection from the deadly disease may be on the horizon.
All 20 healthy adults who received the vaccine in a trial run by researchers from the National Institutes of Health in Maryland produced an immune response and developed anti-Ebola antibodies, the NIH said Wednesday.
None suffered serious side effects, although two people developed a brief fever within a day of vaccination.
