## Resource

Seasonal malaria chemoprevention (SMC)—a program that provides preventive antimalarial medication to young children during the months when malaria is mostly likely to be transmitted—is one of the most cost-effective programs GiveWell has identified. Malaria Consortium’s SMC program has been one of our Top Charities since 2016, and we’ve recommended more than $500 million in grants to the program. Most of our funding to date has supported programs in West Africa, where strong evidence gives us confidence in the effectiveness of the drug combination used. In eastern and southern Africa, malaria chemoprevention programs could potentially help many more children, but we have substantial uncertainties about drug effectiveness in that region. In this episode, GiveWell CEO and co-founder Elie Hassenfeld speaks with Senior Researcher John Macke about the CHAMP trial, a randomized controlled trial of chemoprevention drugs we’re supporting in Malawi, and how it could shape our malaria grantmaking. This research is one example of how GiveWell is building for the future: investing in research now that could substantially expand our ability to direct funding cost-effectively in the years ahead. Elie and John discuss: Why eastern and southern Africa present different challenges: One of the drugs used in seasonal chemoprevention shows widespread resistance in the region, and existing trial evidence about the effectiveness of chemoprevention there has limitations. While we’ve supported SMC in parts of Uganda and Mozambique, we’ve been cautious about scaling up without stronger evidence on which drug combinations work and whether using certain drugs could increase resistance. What this trial will tell us: The trial will test three drugs alone and in different combinations across roughl…
