Factors significantly affecting the risk of immune compared to being susceptible to malaria. Increased probability of infants having only asymptomatic infections (immune) if mother used ITN during pregnancy relative to ITN non-use (as reference = 1); and decreasing probability of being immune to disease as socioeconomic status (SES) decreases, with least poor as reference. *Adjusted for ITN use, socioeconomic status, residence and placental malaria
