Risultati senza precedenti sono stati dati da un vaccino sperimentale contro la malaria sviluppato dall'Istituto statunitense delle allergie e delle malattie contagiose e pubblicati sulla rivista Science.
Fabbricata a partire da parassiti indeboliti estratti dalla zanzara anofela, la cura ha permesso a 6 delle 9 persone trattate con la dose più forte di ottenere il 100% protezione dalla malattia.
La malaria provoca ogni anno 600'000 morti nell'Africa Subsahariana. Sono 30 anni che si prova a produrre un vaccino efficace che ora sembra a portata di mano. Molte verifiche sono tuttavia ancora necessarie e la produzione in larga scala è al momento problematica.
