Effect of vitamin A supplementation on morbidity due to Plasmodium falciparum in young children in Papua New Guinea: a randomised trial

Notes that many individuals at risk of malaria also have micronutrient deficiencies that may hamper protective immunity. Investigates the effect of vitamin A supplementation on malaria morbidity, and finds that it may be an effective low-cost strategy to lower morbidity in young children. Findings suggest that clinical episodes, spleen enlargement, and parasite density are influenced by different immunological mechanisms from infection and anaemia. (Original abstract - amended)
