DRC receives 70,000 Ervebo vaccines to bolster frontline Ebola response

The WHO and partners have allocated 70,000 Ervebo Ebola vaccine doses to the Democratic Republic of Congo to bolster the response to the Bundibugyo-driven outbreak, with 50,000 earmarked for frontline health workers and 20,000 for a late-stage trial to determine cross-protection against Bundibugyo. The deployment occurs amid the fastest, deadliest Ebola surge in the country’s history, and while Ervebo is approved for Zaire ebolavirus, its effectiveness against Bundibugyo remains under study.

DR Congo Ebola Outbreak Becomes Deadliest

DRC's Bundibugyo Ebola outbreak has become the deadliest in the country's history, with about 4,945 confirmed cases and 2,325 deaths across six provinces, and the Bundibugyo strain has no approved vaccines or treatments. The outbreak is moving rapidly, with a roughly 47% case-fatality rate, reflecting weak health systems and complicating response, making it the second-deadliest Ebola epidemic on record behind West Africa's 2014-2016 crisis.
