Sirima SB, et al. - Safety and immunogenicity of Plasmodium falciparum Apical Membrane Antigen 1 Diversity Covering (PfAMA1-DiCo) candidate vaccine was tested among European and African adults who received AMA1-DiCo with either Alhydrogel or GLA-SE. Findings revealed that regardless of the adjuvant, AMA1-DiCo vaccine was safe and immunogenic, however, GLA-SE appeared more potent than Alhydrogel at inducing IgG responses.
