Phase Ia study to assess the safety and immunogenicity of the Pvs25-IMX313 vaccine, administered in Matrix-M1 adjuvant in healthy adults in the UK

This is an open-label, single-center, non-randomized, first-in-human Phase Ia study. Volunteers will be recruited into one of three groups (n=8-10 per group) at the Centre for Clinical Vaccinology and Tropical Medicine (CCVTM), Oxford over approximately 18 months. All volunteers will receive three doses of Pvs25-IMX313 in Matrix-M1, administered intramuscularly and given four weeks apart. Enrolment will be staggered with clinical and safety reviews, follow-up visits, and monitoring via a diary card.
