f (FVO), 3 (3D7) and h (HB3) in groups 1, 2 and 3 indicate the order of antigen administration.
NA mix - an equimolar mixture of AMA1 antigens from the FVO, HB3 and 3D7 strains of P. falciparum, administered at all three immunization time points.
DiCo mix - an equimolar mixture of the three Diversity-covering (DiCo) proteins, administered at all three immunization time points.
