Intermittent preventive antimalarial treatment for Tanzanian infants: follow-up to age 2 years of a randomised, placebo-controlled trial (Publications)
Stopping antimalarial chemoprophylaxis can be followed by increased risk of malaria, suggesting that it interferes with the development of antimalarial immunity. We report analysis of extended follow-up [...] double-blind trial of intermittent preventive antimalarial treatment in infants. The rate of clinical malaria (events per person-year at risk, starting 1 month after final dose of intermittent treatment) was [...] 36%, 95% CI 11-53). Intermittent treatment produced a sustained reduction in...
