Is this trial a fit for you?

Likely a good fit

Ideal candidates are children aged 3–59 months who live in the catchment area of a participating health centre in Burkina Faso or Mali and whose parent or guardian can give written consent.

Probably not a fit

Children with known chronic illnesses, a history of severe allergic reactions to vaccines, or those living outside participating catchment areas are unlikely to receive benefit from participation.

What this trial studies

This is a multi-site, phase-4, cluster-randomised non-inferiority trial in Burkina Faso and Mali where health centre catchment areas are randomised to different vaccine delivery strategies. One arm delivers the 3-dose R21/Matrix-M primary series aligned with seasonal malaria chemoprevention (SMC) for children aged 3–59 months, while the comparator arm uses country-specific routine EPI or pre-SMC campaign delivery for children aged 5–36 months. Effectiveness will be measured by clinical malaria incidence as well as vaccine coverage, acceptability, and operational feasibility under real-world conditions. Clusters are followed through the malaria season to compare health and programmatic outcomes between the integrated and routine delivery approaches.

Why it matters

Potential benefit: If successful, this integrated approach could reduce malaria cases in young children and simplify delivery by combining vaccination with existing SMC campaigns.

How similar studies have gone: Previous trials of R21/Matrix-M have shown promising efficacy in seasonal settings, but combining R21 delivery with SMC in routine programmatic delivery is largely untested.
