Ervebo Vaccine Clinical Trial Launches in Bunia

A clinical trial of the Ervebo vaccine, targeting 20,000 people over 9-12 months, began vaccinating healthcare workers in Bunia, Ituri on Sept 19, 2026. Ervebo is already proven effective against the Zaire ebolavirus strain; the trial will test whether it also protects against the Bundibugyo strain driving the current outbreak, for which no specific vaccine yet exists. More than 3,000 people had already been vaccinated in Tshopo province and over 700 in Bas-Uélé under the same initiative.
