Merck’s experimental and unlicensed Ebola vaccine is being used in latest outbreak

The World Health Organization has started to vaccinate thousands of people considered at high risk of contacting the infectious and often-deadly disease Ebola in the Democratic Republic of Congo. The WHO said Monday it is working with NGOs and community leaders to administer an experimental vaccine that was studied in a trial in Guinea in 2015, but has not yet been used to contain a major outbreak. Most are in a remote town, but there are four confirmed cases in Mbandaka, the provincial capital which has a population of more than 1 million people.
