Brief Summary:
This epidemiology study was conducted in parallel with the EPI-MAL-002 (NCT02374450) and EPI-MAL-003 (NCT03855995) studies, enrolling participants from the same health and demographic surveillance system (HDSS) (or equivalent system) populations. The co-primary objectives were to produce longitudinal estimates of parasite prevalence in humans and to record the usage of malaria control measures in areas where the EPI-MAL-002 and EPI-MAL-003 studies were conducted.
Detailed Description:
This study involved 10 annual cross-sectional surveys conducted during malaria peak transmission seasons. The surveys provided point estimates of parasite prevalence and subsequently enabled a longitudinal assessment of the level of endemicity in each area covered by EPI-MAL-002 and EPI-MAL-003. The study was conducted in parallel with EPI-MAL-002 and EPI-MAL-003 to assess parasite prevalence and malaria control measures before (EPI-MAL-002) and after (EPI-MAL-003) vaccine introduction.
By taking into account variations in malaria transmission intensity (MTI) and malaria control intervention coverage, it enabled a more complete assessment of the benefits and risks of the vaccine introduction, and thereby provided greater insight into the potential vaccine impact in EPI-MAL-002/-003 by adjusting incidence data for overall changes in transmission and other malaria control intervention coverage, and assisted in the generalisation of results to other populations.
