CON-S vaccination induces higher plasma antibody blocking of the V3-glycan and CD4 binding site on HIV-1 Env. Plasma competition ELISAs for various broadly neutralizing and nonneutralizing monoclonal antibodies that bind to various sites on HIV-1 Env were performed. The antibody and Env used for competition are indicated above each graph. Values are the means and SDs for all six animals. Values for each macaque were measured in triplicate. Twenty percent is the cutoff for positive blocking responses. *, exact Wilcoxon test, FDR corrected, P < 0.05.
