Researchers from the University of Oxford and their partners have today reported findings from a Phase IIb trial of a candidate malaria vaccine, R21/Matrix-M, which demonstrated high-level efficacy of 77% over 12-months of follow-up.
In their findings (posted on SSRN/Preprints with The Lancet) they note that they are the first to meet the World Health Organization’s Malaria Vaccine Technology Roadmap goal of a vaccine with at least 75% efficacy.
The authors report (in findings in press with The Lancet) from a Phase IIb randomised, controlled, double-blind trial conducted at the Clinical Research Unit of Nanoro (CRUN) / Institut de Recherche en Sciences de la Santé (IRSS), Burkina Faso. 450 participants, aged 5-17 months, were recruited from the catchment area of Nanoro, covering 24 villages and an approximate population of 65,000 people.
