Impact of introducing RTS,S/AS01_E malaria vaccine on mortality in young children in Ghana, Kenya, and Malawi: an observational evaluation of a cluster-randomised implementation programme

This study evaluates the impact of the RTS,S/AS01_E malaria vaccine on mortality rates in young children in Ghana, Kenya, and Malawi over a 46-month period following its introduction in 2019. The authors aimed to determine whether the vaccine significantly reduced overall mortality in children eligible for three doses compared to non-eligible children, finding a notable reduction in mortality, with approximately one in eight deaths averted in areas with moderate vaccine coverage. The results underscore the importance of accelerating malaria vaccine deployment in regions where malaria remains a leading cause of child mortality.
