The Against Malaria Foundation (AMF) is a British charity that provides funding for mass distribution of long-lasting insecticide-treated nets (LLINs) to populations at high risk of malaria. It was founded in August 2004 by Rob Mather (Against Malaria Foundation 2010; Mather 2020).
As of June 2021, GiveWell estimates that AMF can deliver a LLIN at a cost of about $5, and that a donation to AMF in the range of $3000–$5000 is expected to save a life (GiveWell 2020a; GiveWell 2020b; GiveWell 2021). (The cost of delivering a net is much lower than the cost of saving a life because a small fraction of people who receive a net would otherwise have died of malaria, and because of other factors (GiveWell 2020c).)
In addition to funding distribution of nets, AMF has more recently supported research on piperonyl butoxide (PBO) nets, a new type of LLIN (Hollander 2020). Mosquito populations appear to have become more resistant to standard insecticides: according to GiveWell’s rough estimates, this resistance has reduced the effectiveness of insecticide-treated nets by one third in the areas where AMF operates (GiveWell 2020d). Against resistant mosquitoes, PBO nets appear to be more effective than standard insecticide-treated nets: an AMF-funded trial—the largest such trial to assess the effectiveness of PBO nets to date—found that PBO nets reduced malaria 26%, 27% and 16% more than did conventional LLINs after 6, 12 and 18 months, respectively (Sherratt 2019).
AMF is a highly transparent organization. The AMF website lists every donation received (Against Malaria Foundation 2021a) and every LLIN distributed (Against Malaria Foundation 2021b), as well as other related information (Against Malaria Foundation 2021c).
AMF has been a GiveWell top-rated charity every year since 2010, with the exception of 2013, when it was excluded from their ranking due to lack of room for more funding (Karnofsky 2013). AMF is also included in The Life You Can Save’s list of “best charities” (The Life You Can Save 2021).
