"I do think this is one of the challenges we'll have to see, whether we're able to contain, control and end the current outbreak with the current security situation, or do we move into the idea that this becomes more of an endemic Ebola outbreak in this region, which we've never really confronted", Dr. Redfield told The Washington Post.
A total of 2100 doses of "rVSV-Ebola" vaccine are to be administered to the health workers to protect them against Zaire type virus, the strain that is now circulating in some parts of DRC.
Health workers are usually among the first to be infected in an Ebola outbreak. It will be administered only to around 2000 first contact health care workers who are working near the borders of DRC in the north Kivu province says the WHO and would not be available for the general public.
Ebola first appeared in 1976 in Sudan and Congo, and gets its name from a river in the latter nation. The vaccine was given to more than 16,000 volunteers in Africa, Europe and the United States in 2015, and was found to be effective against the Ebola virus.

The minister explained that the vaccine is only available for frontline health workers who are at high risk of contracting EVD as they manage suspected cases. "This is targeted vaccination", Dr Aceng emphasized.
