CEPI plans to start Phase II trials of a Rift Valley fever vaccine in Kenya, following successful Phase I results in the UK. The trials, led by the University of Oxford and KEMRI-Wellcome Trust, will involve 240 healthy adults to assess safety and efficacy. The vaccine, ChAdOx1 RVF, uses the same platform as the Oxford-AstraZeneca Covid-19 vaccine and has shown promise in both human and livestock protection.
