Congo has begun vaccinating healthcare staff against Ebola in Bunia, the epicenter of the fastest-growing outbreak of the disease in history. Health workers and other front-line workers in the Ebola response are being prioritized to receive the Ervebo vaccine. That vaccine was effective in past Ebola outbreaks caused by a different, more common type of virus. Clinical trials are ongoing to find a licensed vaccine for the current outbreak, caused by the Bundibugyo virus, which has no licensed vaccine or treatment. The rollout is targeting the Bunia and Mongbwalu zones in Ituri province, health authorities said Saturday. Both zones are among the hardest hit by the virus.
