Malaria Consortium is a British charity that works on preventing, controlling, and treating malaria and other communicable diseases in Africa and Asia.

Its seasonal malaria chemoprevention (SMC) program—one among many programs carried out by this organization—distributes preventive anti-malarial drugs to children under five to reduce incidence during the high transmission season. As of June 2021, GiveWell estimates that SMC can protect a child from malaria at a cost of about $7, and that a donation in the range of $3000–$5000 is expected to save a life (GiveWell 2020a; GiveWell 2020b; GiveWell 2021). (The cost of protecting a child from malaria is much higher than the cost of saving a life because a small fraction of people who receive protection would otherwise have died of malaria, and because of other factors (GiveWell 2020c).)

Malaria Consortium's SMC program has been a GiveWell top-rated charity since 2016 (Sanchez et al 2021), and its cost-effectiveness is estimated to be in the same range as GiveWell's other priority programs (GiveWell 2020a). Malaria Consortium is also featured in The Life You Can Save's list of "best charities" (The Life You Can Save 2021).
