Vaccination efforts against Ebola have commenced in the Democratic Republic of the Congo, with health workers in Ituri province receiving doses on Saturday. The campaign, concentrated in areas hardest hit by the outbreak, aims to protect frontline medical personnel who face heightened exposure to the virus. Ituri province, located in the northeastern part of the country, serves as the epicenter of what health officials have characterized as the fastest-growing Ebola outbreak on record.
Approximately 50,000 health and other frontline workers are expected to receive the Ervebo vaccine through the initiative, which is being coordinated by the World Health Organization and Doctors Without Borders. The rollout will extend to North Kivu province, where case counts have increased markedly in recent weeks. The vaccine was originally developed to address the Zaire strain of Ebola, but it is being deployed against the current outbreak caused by the Bundibugyo virus variant, for which no licensed vaccine or proven treatment currently exists.
The use of Ervebo in this context operates under a compassionate-use programme, a regulatory framework that permits deployment of medical products in serious disease situations without specific approval for that particular application. Officials plan to monitor the vaccine’s effectiveness in 20,000 recipients over the course of up to one year, while clinical trials continue to develop licensed vaccines tailored to the Bundibugyo strain. WHO experts have noted that preliminary data from animal studies suggest the vaccine may offer some degree of protection.
Since May, the outbreak has resulted in at least 3,639 deaths and approximately 7,541 confirmed cases, with around 1,823 individuals having recovered. WHO authorities reported in August that 70,000 doses of Ervebo had been authorized for use in the country. While WHO officials have observed what they characterize as encouraging indicators that transmission rates may be declining, Doctors Without Borders cautioned that clear evidence of epidemic control remains absent.
