But funding for ACTs is uncertain. In 2012, the AMFm subsidized about 60% of the world’s total supply of the drugs. With an unusual approach — supplying most of the drugs through small, for-profit pharmacies, rather than public clinics — the programme got more ACTs into circulation. But donors were not convinced that the drugs were reaching the neediest patients. In November 2012, the Global Fund announced that it would merge the AMFm into its broader malaria campaign (see Nature 491, 508; 2012). With so many demands on aid funding, some health experts worry that support for ACT distribution will falter.Fabienne Jouberton, AMFm’s senior officer for price negotiations, acknowledges that it will probably become much more difficult for A. annua growers and drug manufacturers to plan ahead. Rather than negotiating with a single body — the AMFm — they will have to assess demand separately in each individual country. “It’s not optimal,” she says.
