As health workers in the Democratic Republic of Congo (DRC) continue to battle an ongoing Ebola outbreak, scientists around the world are racing to develop a vaccine against the strain of the virus that’s causing it.

Two approved vaccines exist for Ebola, but they target the Zaire strain of the virus, not the Bundibugyo strain causing the 2026 outbreak, which has so far killed 61 people with 359 confirmed cases in the DRC and neighbouring Uganda.

In this episode, we speak to two scientists at the Oxford Vaccine Group at the University of Oxford, Teresa Lambe and Rebecca Makinson, who are developing a vaccine candidate for Bundibugyo virus. On June 1, they were among three research groups to receive fast-track funding from the Coalition for Epidemic Preparedness Innovations, alongside Moderna and IAVI.
