Congo begins vaccinations to fight the fastest-growing Ebola outbreak in history

One hundred days after the official declaration of the Ebola epidemic in the Democratic Republic of Congo, researchers are in a race against time.

As of 24 August, the Bundibugyo variant of the virus had 5,656 confirmed cases and 2,715 deaths.

Health workers and other people working on the front lines of the Ebola response are among the first to receive the vaccine.

However, the vaccine being distributed this week is licensed for another strain, and its effectiveness against the Bundibugyo strain of Ebola has not been determined.
