To evaluate antibody specificities induced by SIV versus HIV-1 envelope antigens in non-human primate (NHP), we profiled binding antibody responses to linear epitopes in NHP studies with HIV-1 or SIV immunogens. We found that overall HIV-1 Env IgG responses were dominated by V3, notably with the exception of responses to the RV144 vaccine strain immunogen (A244 Env) that was dominated by V2, whereas the anti-SIVmac239 Env responses were dominated by V2 regardless of vaccine regimens.
