The Democratic Republic of Congo has launched a vaccination campaign in Kisangani, targeting healthcare workers and other aid workers amid a deadly ebolavirus outbreak involving the Bundibugyo variant that has cost at least 2,744 people their lives, utilizing doses of the Ervebo vaccine released by the World Health Organization.
While the current epidemic in central Africa stems from the Bundibugyo variant—for which no approved vaccine currently exists—public health officials are deploying the Ervebo vaccine under a compassionate-use framework. Ervebo was developed to target a different variant of the ebolavirus, the Zaïre strain. This strategy seeks to protect those on the front line in Tshopo and five other affected provinces, where ongoing conflict severely restricts healthcare access.
In Plain English: The Clinical Takeaway
- Cross-Protection Strategy: Health teams are administering a vaccine developed for the Zaïre strain to protect against the Bundibugyo variant, as health authorities see indications that the Ervebo vaccine may offer some protection because the variants are related.
- Compassionate-Use Protocol: Because no approved vaccine exists for the Bundibugyo variant, the intervention relies on a compassionate-use program to safeguard those on the front line first.
- Active Surveillance: Out of 70,000 total doses released by the World Health Organization, 20,000 doses are being used to investigate the effectiveness of the vaccine against the Bundibugyo variant.
Epidemiological Burden and Vaccine Deployment Dynamics
The Democratic Republic of Congo remains a focal point for filovirus transmission. State reports indicate that 5,794 ebola cases have been registered across the country. The current outbreak in the eastern regions is driven by the Bundibugyo variant. According to reports from the Associated Press cited by Congolese authorities, the country has received 50,000 doses from a United Nations coordination group out of the 70,000 total Ervebo doses released by the World Health Organization.
Roger Kamba, the Minister of Health, formally initiated the campaign in Kisangani, the capital of Tshopo province, urging all healthcare workers to be vaccinated. The deployment protocol implements a compassionate-use program, allowing a medicine to be used for a serious illness even if it is not specifically approved for that purpose. Out of the total vaccine supply, authorities are using 20,000 doses to evaluate effectiveness against the Bundibugyo variant.

| Primary Recipients | Healthcare workers and aid workers in Tshopo and affected provinces |
Regional Trajectories: Containment in Uganda Versus Ongoing Crisis in Congo
While the Democratic Republic of Congo works to stem its active transmission chains, neighboring Uganda presents a contrasting epidemiological outcome. On the exact day Congo initiated its vaccination drive, the Africa Centres for Disease Control and Prevention (Africa CDC) alongside the World Health Organization officially declared the end of Uganda’s ebola outbreak.

The outbreak in Uganda was much smaller than in Congo, totaling 20 confirmed cases and two fatalities, with 15 of those cases originating from Congo across the shared border of over 800 kilometers. The final Ugandan patient was discharged on July 16, crossing the critical threshold of 42 days—twice the incubation period of the virus—without recording a single new infection. WHO Director Tedros Adhanom Ghebreyesus credited the resolution to decisive state action. „Oeganda heeft aangetoond dat ebola-uitbraken met daadkrachtig optreden snel onder controle kunnen worden gebracht”, noted Tedros, praising the government’s systematic deployment of active case finding, contact tracing, isolation, clinical care, and infection prevention and control measures at healthcare facilities and border crossings.

Conclusion
The simultaneous launch of vaccination efforts in the Democratic Republic of Congo and the closure of the outbreak window in Uganda illustrate the dual realities of infectious disease management in Central Africa.
