In August, researchers at Oxford University announced that they will begin a trial of a potential vaccine on healthy UK volunteers once ethical approval is granted, which will eventually extend to the Gambia and Mali. 
Mwezi Agosti, watafiti wa Chuo Kikuu cha Oxford walitangaza kwamba wataanza majaribio ya kinga kwa wa-Ingereza waliojitolea kushiriki zoezi hilo wakishapata ruhusa ya kuzingatia maadili ya tafiti, na kisha zoezi hilo linatarajiwa kufanyika pia kwenye nchi za Gambia na Mali.
