Ugandan researchers begin Ebola vaccine trial in Masaka
The first participants have been vaccinated in an Ebola vaccine trial in Masaka, Uganda. The launch comes in a country that has experienced Bundibugyo-virus outbreaks; the licensed vaccine developed after the West African epidemic targets a different Ebola species.

Key facts
- The supplied source excerpt does not verify the Oxford Vaccine Group’s role or the details of its collaboration with the Ugandan research team.
- The supplied source excerpt does not verify Dr Nicole Lurie’s characterization of the Bundibugyo outbreak.
- The supplied source excerpt does not verify Dr Nicole Lurie’s claim about licensed vaccines or treatments for Bundibugyo virus.
- The supplied source excerpt does not verify the stated estimates for lives saved by the Oxford-AstraZeneca COVID-19 vaccine or doses used worldwide.
- The outlets’ headlines report that Uganda launched an Ebola vaccine trial (per modernghana.com, France 24, oxfordstudent.com).
The brief
Researchers in Uganda have vaccinated the first participants in an Ebola vaccine trial in Masaka, according to Cherwell. The outlet says the vaccinations took place on 6th October.
Headlines from Modern Ghana, France 24, The Oxford Student and Africanews also report that an Ebola vaccine trial has launched or begun in Uganda; The Oxford Student describes the vaccine as Oxford-developed and the study as a Phase I clinical trial. Cherwell reports that the Oxford Vaccine Group is working with the Ugandan research team.
The group’s stated contribution includes support for the study’s scientific design and coordination, safety oversight, and assessment of vaccine safety and immunogenicity. The article does not provide a participant count or details of the vaccine candidate beyond the information in the headlines.
Dr Nicole Lurie, CEPI’s Executive Director for Emergency Preparedness and Response, told Cherwell that the Bundibugyo outbreak remains the fastest-growing and second-largest Ebola outbreak recorded. Lurie also said there is currently no licensed vaccine or treatment for that outbreak.
Those assessments are attributed to Lurie; Cherwell does not provide separate figures for the outbreak or further details about available care. Lurie said CEPI needs US$128M to keep its emergency research and development work on Bundibugyo moving. She warned that insufficient additional funding could prevent development of the vaccine candidates.
Her remarks link the funding request to continued research and development, but the article does not identify a funding decision or a deadline. Cherwell also cites the Oxford-AstraZeneca ChAdOx1 COVID-19 vaccine as a precedent for Oxford vaccine development.
It says the vaccine received emergency-use approval in the UK in December 2020, was estimated to have saved six million lives during 2021, and had more than 3 billion doses used worldwide. These figures concern the COVID-19 vaccine, not the Ebola trial.
The immediate documented next steps are the trial’s ongoing work with the Ugandan research team and the research and development activity Lurie says CEPI’s funding would support. The account gives no further trial timetable, recruitment target or decision date.
The headlines identify the trial as underway in Uganda, while Cherwell supplies the account of the first vaccinations and the stated research, safety and funding details.
Why it matters
- The trial tests a vaccine against Bundibugyo virus, a species linked to past outbreaks in Uganda and the Democratic Republic of the Congo; the licensed Ebola vaccine targets a different species. If the candidate proves safe and effective, it could give health authorities a tool to protect people at risk in future Bundibugyo outbreaks, where existing vaccine coverage may not apply.
What to watch next
- Over the next several weeks, the Ugandan trial team’s updates on recruitment will show how quickly the Masaka study is enrolling participants.
- In the coming weeks and months, watch for safety-monitoring updates, including whether investigators report any serious adverse events among vaccinated participants.
- As follow-up data accrue, investigators’ assessments of immune responses will indicate whether the vaccine prompts the responses the trial is designed to measure.
- Watch for Uganda’s health authorities and researchers to clarify how trial findings relate to Bundibugyo-virus protection, since the licensed Ebola vaccine targets a different species.

How we got here
Uganda’s 2007–08 Bundibugyo Ebola outbreak was the first recorded outbreak caused by Bundibugyo virus. In 2012, the Democratic Republic of the Congo recorded another Bundibugyo-virus outbreak, with 57 cases and 29 deaths.
The distinction among Ebola viruses matters because the licensed vaccine that emerged from the 2014–16 West African epidemic targets the Zaire ebolavirus species, not Bundibugyo virus. In November 2019, the European Commission authorized Merck’s rVSV-ZEBOV vaccine, Ervebo, for prevention of disease caused by Zaire ebolavirus.
