Congo has started a vaccination campaign targeting healthcare workers in Bunia to combat what officials characterize as the most rapidly expanding Ebola outbreak in history. The initiative, which began on Saturday, prioritises front-line healthcare staff amid ongoing challenges posed by the outbreak caused by the Bundibugyo virus.

The vaccination rollout is particularly focused on the Bunia and Mongbwalu areas of Ituri province, the regions severely impacted by the epidemic. In total, the campaign plans to vaccinate approximately 20,000 front-line workers within a six to nine-month timeframe. The Ervebo vaccine will be administered as part of a compassionate-use programme while ongoing clinical trials are conducted. Health authorities aim to safeguard those individuals who are most at risk due to their essential role in managing the outbreak.

Current Situation of Ebola Outbreak

As of the latest reports, Congo has confirmed 7,541 cases of Ebola, with 3,639 fatalities and 1,823 recoveries. The outbreak is primarily concentrated in Ituri province, making it the deadliest among the 17 documented Ebola outbreaks in the country’s history. The situation has deteriorated, influenced by numerous factors such as insecurity, displacement of communities, a strike by health workers, and significant population movements.

The World Health Organisation (WHO) has described the conditions as challenging, expressing concerns that the outbreak could surpass the toll of the 2014-2016 West Africa Ebola epidemic, which resulted in over 11,000 deaths mainly in Guinea, Liberia, and Sierra Leone.

With public health infrastructure strained, the approach to controlling the disease has become increasingly complex. Major General Gaby Kasongo Mulumba, Ituri’s military governor, emphasized the importance of this vaccination campaign by noting that it is crucial to protect lives and that targeting front-line workers isn’t arbitrary given their heightened exposure to the virus.

Concerns from Healthcare Workers

Healthcare professionals in Bunia have expressed varying views on the vaccination. One worker, Dr Jeannot Elua, commented that receiving the vaccine is an obligation for health staff, acknowledging its perceived benefits. He stated that many had received prior vaccinations as part of mandated health protocols.

Another front-line health worker, Dr Jean Paul Uzele, reported uncertainty regarding the necessity of a second vaccine. He indicated that while he would accept a new dose if offered, he remains unsure whether further vaccination is essential for those who have already been vaccinated during earlier outbreaks.

Last month, another campaign involving the Ervebo vaccine was initiated in Kisangani, Tshopo province, targeting 14 health zones across three provinces. The WHO confirmed that a total of 70,000 doses of the vaccine have been authorised for use in Congo, with 50,000 allocated for front-line health workers, while the remaining doses will assist in clinical trials to determine their efficacy against the Bundibugyo virus, which currently lacks both licensed vaccines and treatments.

While the Ervebo vaccine is licensed for the Zaire strain of the Ebola virus, authorities noted its potential to offer limited protection against the Bundibugyo variant. However, rigorous study is ongoing to ascertain the vaccine’s effectiveness against this specific strain, underscoring the urgent need for comprehensive measures to control the outbreak.
