Uganda Launches Ebola Vaccine Trial Amid New Outbreak
KAMPALA,Feb.1 (Xinhua) — The World health Organization (WHO) has donated 2,160 doses of an Ebola trial vaccine to Uganda to evaluate its efficacy in combating the virus. this comes after a recent outbreak claimed the life of a 32-year-old male nurse at Mulago National Referral Hospital in Kampala, marking the eighth Ebola outbreak in the East African nation.
The WHO is collaborating with Uganda’s Ministry of Health, Makerere University Lung Institute, and the Ugandan Virus Research Institute, alongside global filovirus and trial experts, to initiate the trials. “The aim of the vaccine trial is to evaluate a potentially efficacious candidate vaccine, and if efficacious, to possibly contribute to ending the ongoing outbreak and protect populations at risk in the future,” saeid the WHO.
Eligible participants include those at the highest risk of sudan Ebola virus disease (SVD), such as close contacts of confirmed cases or individuals who have died from the disease. Study sites will be located in areas where thes contacts reside.
Ther are currently no approved treatments or vaccines for the Sudan virus. However, early supportive treatment has been shown to significantly reduce fatalities. During uganda’s previous SVD outbreak, which began in September 2022 and ended in January 2023, there were 164 cases and 77 deaths.
A WHO committee of external experts evaluated candidate vaccines during that outbreak, providing recommendations for their suitability in clinical trials. ”The vaccine trial processes underway include orientation of the research teams on the trial procedures, and logistics arrangements. Research teams have been deployed to the field to work along with the surveillance teams as approvals are awaited,” the WHO stated.
Case fatality rates for SVD have historically ranged from 41 percent to 100 percent in past outbreaks, underscoring the urgency of this trial.

Uganda is taking a crucial step in combating the deadly Sudan Ebola Virus Disease (SVD) with the launch of a new vaccine trial. The World Health Organization (WHO) has donated 2,160 doses of an experimental vaccine, marking a critically important effort to curb the ongoing outbreak. To delve deeper into this initiative, we spoke with Dr. Amina Kato, an infectious disease specialist and one of the leading experts on Ebola research, to understand the trial’s meaning, its collaborative efforts, and the potential impact on future outbreaks.
The Importance of the Ebola Vaccine Trial
Senior Editor: Dr. Kato, thank you for joining us. Could you start by explaining why this trial is so critical for Uganda and the global fight against Ebola?
Dr. Amina Kato: Absolutely. This trial is pivotal because it targets the Sudan strain of the Ebola virus, for which there are currently no approved vaccines or treatments.the Sudan variant has historically had a case fatality rate ranging from 41% to 100%, making it one of the most lethal strains. By evaluating this experimental vaccine, we’re not only aiming to contain the current outbreak but also to develop a tool that could protect vulnerable populations in the future. It’s a proactive step to prevent the devastating loss of life we’ve seen in past outbreaks.
Collaborative Efforts Behind the Trial
Senior Editor: this trial involves multiple organizations, including the WHO, Uganda’s Ministry of Health, and local institutions like Makerere University. How does this collaboration enhance the trial’s effectiveness?
Dr. Amina Kato: Collaboration is the backbone of this initiative. The WHO brings global expertise and resources, while Uganda’s Ministry of Health ensures that the trial aligns with national health priorities. Local institutions like Makerere University and the Ugandan Virus Research Institute provide critical on-the-ground knowledge and infrastructure. This synergy allows for a well-coordinated trial that integrates global standards with local context, enhancing both its efficiency and relevance.
Who Are the Eligible Participants?
Senior Editor: The trial is targeting close contacts of confirmed SVD cases or deceased individuals. Why is this group prioritized, and what does this mean for the trial’s success?
Dr. Amina Kato: Close contacts are at the highest risk of contracting the virus, so prioritizing them ensures that the vaccine is tested in a population where the need and potential benefit are greatest. This approach also allows us to gather data on the vaccine’s efficacy in real-world scenarios. If accomplished, it could considerably reduce transmission chains, which is key to controlling outbreaks. Additionally, focusing on this group aligns with ethical considerations, as it provides protection to those most vulnerable.
Lessons from the Previous Outbreak
Senior editor: Uganda’s previous SVD outbreak, from september 2022 to January 2023, saw 164 cases and 77 deaths. What lessons from that outbreak have informed this trial?
Dr. Amina Kato: The previous outbreak highlighted the urgent need for effective interventions, particularly vaccines. It also reinforced the importance of early supportive care, which, while not a cure, can significantly reduce fatalities. The WHO and other partners used that outbreak to evaluate candidate vaccines, which laid the groundwork for this trial. Additionally, the experience underscored the necessity of rapid response and community engagement, which are critical components of this current initiative.
The Challenge of High Case Fatality Rates
Senior Editor: SVD has historically had case fatality rates ranging from 41% to 100%. How does this trial aim to address such a high mortality rate?
Dr. Amina Kato: the high fatality rate is a stark reminder of the virus’s lethality. This trial aims to provide a preventive measure that can stop the virus in its tracks before it claims more lives. If the vaccine proves effective, it could drastically reduce the spread of the virus, thereby lowering the number of cases and fatalities. Additionally, the trial’s data will inform future strategies for managing outbreaks, including rapid deployment of vaccines in affected areas.
Senior Editor: Dr. Kato, thank you for sharing these insights. It’s clear that this trial represents a significant advancement in the fight against Ebola. For our readers, this initiative offers hope not only for ending the current outbreak but also for safeguarding communities against future threats.
Dr.Amina Kato: Thank you. it’s a collective effort, and I’m hopeful that this trial will pave the way for more effective solutions in the global battle against Ebola.
