Congo's health minister resigned on Monday after being stripped of responsibility for managing the country's Ebola outbreak, potentially paving the way for the introduction of a second vaccine to contain the spreading epidemic.

Oly Ilunga has overseen Congo's near year-long response to what is the second deadliest Ebola outbreak in history. It has killed more than 1,700 and been declared an international health emergency by the World Health Organization (WHO).

President Felix Tshisekedi on Saturday appointed a team led by Jean-Jacques Muyembe, the head of Congo's biomedical research institute, to coordinate the government's response in Ilunga's place.
