DRC Receives 16,000 Ervebo Vaccine Doses Amid Record Ebola Outbreak

Health authorities in the Democratic Republic of Congo received 16,250 doses of the Ervebo vaccine late Friday, August 21, 2026, arriving at N’djili International Airport in Kinshasa to combat the fastest Ebola outbreak in history, according to reports from Agence France-Presse and The Associated Press.

The shipment marks the initial arrival of 70,000 total doses promised by the World Health Organization and its partners, with additional supplies expected to land early next week, according to the Congolese Ministry of Health. Of the total allocation secured for the country, 20,000 doses are designated for a clinical trial, while 50,000 doses are intended for frontline and health workers, the World Health Organization stated.

Vaccine Deployment and Clinical Trial Plans

The current epidemic is driven by the rare Bundibugyo virus, which currently lacks an approved specific treatment or vaccine. While the Ervebo vaccine, manufactured by Merck and produced in Germany, is licensed to treat the Zaire strain of Ebola, World Health Organization experts are initiating a full-scale human trial to test whether it offers cross-protection against the circulating Bundibugyo strain.

The Ervebo vaccine has already been used several times, and in particular on a very large scale during the 2018-2020 outbreak Samuel Roger Kamba, the Democratic Republic of Congo’s Minister of Health, told the press on the tarmac of Kinshasa airport.

While World Health Organization experts do not yet know definitively if Ervebo protects humans against the Bundibugyo strain, early data from animal trials suggest it could offer some protection, according to Agence France-Presse. Other vaccines targeting the Bundibugyo strain remain in clinical trial phases, including an mRNA candidate developed by Moderna and another by the University of Oxford, alongside an rVSV Bundibugyo vaccine developed by Singapore-based Hilleman Laboratories.

Unprecedented Spread and On-the-Ground Challenges

The country’s 17th Ebola outbreak was officially declared on May 15, though health officials believe it was spreading for several weeks prior, primarily hitting northern and eastern regions where state presence is weak and health infrastructure is lacking. As of Friday, August 21, 2026, the outbreak has recorded 2,516 deaths out of 5,290 confirmed cases, according to figures released by Congolese authorities and cited by The Associated Press.

It is growing exponentially Julien Harneis, the United Nations’ senior Ebola coordinator, warned on Friday, August 21, 2026, according to Agence France-Presse. Data from the Africa Centre for Disease Control indicates transmission has not yet peaked and could potentially reach three times its known rate.

Containment efforts continue to face severe operational hurdles. Armed conflict between the government and rebel groups controlling key cities in the hot spots, attacks on medical personnel and facilities, an itinerant labor population, and displaced citizens have severely hampered the public health response, according to The Associated Press. Furthermore, symptoms of the Bundibugyo virus overlap with other common illnesses like malaria, allowing the virus to easily spread undetected without robust diagnostic infrastructure.
