Résumé : Seasonal malaria chemoprevention (SMC) by mass administration of sulfadoxine pyrimethamine + amodiaquine (SPAQ) reduces the burden of malaria in children aged 3–59 months. The occurrence of adverse drug reaction (ADR) may affect the success of this intervention. There are few studies of SMC adverse event surveillance in sub-Saharan Africa, particularly in Burkina Faso, a highly endemic country. Our main objective was to characterize the ADRs reported during SMC campaigns in Burkina Faso. Secondly, we evaluated the performance of the pharmacovigilance integrated into the SMC program in order to support safe administration of SMC.
