DRC's Fastest-Spreading Ebola Outbreak Has No Approved Vaccine to Slow It

The DRC's 17th Ebola epidemic — the fastest-spreading ever recorded, per UN Secretary-General Guterres — is caused by the Bundibugyo ebolavirus species, which has no approved vaccine or treatment. In past Zaire ebolavirus outbreaks, ring vaccination helped break transmission chains. Here, containment depends entirely on case isolation, contact tracing, and supportive care. With 5,794 cases and 2,786 deaths across six provinces, that gap is acute.
