The U.S. Food and Drug Administration has for the first time approved a vaccine for the prevention of the deadly Ebola virus disease.
The agency announced the approval of Ervebo, a single-dose, injectable vaccine manufactured by American pharmaceutical company Merck. The announcement, made Thursday, comes a month after the European Union and the World Health Organization, the global health arm of the United Nations, both approved the Ebola vaccine.
Ebola cases are very rare in the United States. Those that have occurred have been the result of people getting infected in other countries and then travelling to the United States, or health workers falling ill after treating Ebola patients.
