Abstract
Malaria remains a significant global health challenge, particularly in sub-Saharan Africa, where it contributes to high morbidity and mortality rates. Natural immunity to malaria, acquired through repeated exposure to Plasmodium parasites, provides partial protection against severe disease but does not prevent infection. This review explores the mechanisms underlying natural immunity, including the roles of innate and adaptive immune responses, and the impact of factors such as age, genetics, and repeated exposure. It also examines the implications of natural immunity for malaria control strategies, particularly in endemic regions where partial immunity helps reduce the disease burden. The review highlights recent advances in immunological research, including the identification of immune markers and biomarkers that correlate with malaria resistance. Additionally, it discusses how natural immunity can inform the development of more effective vaccines and therapies. The review concludes by identifying key gaps in current research and suggesting future directions, including enhancing natural immunity through vaccines and immunotherapies, and the importance of global collaboration in advancing malaria control efforts
