Increased immunogen valency improves the maturation of vaccine-elicited HIV-1 VRC01-like antibodies.

ABSTRACT: Antibodies belonging to the VRC01-class display broad and potent neutralizing activities and have been isolated from several people living with HIV (PLWH). A member of that class, monoclonal antibody VRC01, was shown to reduce HIV-acquisition in two phase 2b efficacy trials. VRC01-class antibodies are therefore expected to be one component of an effective HIV-1 vaccine elicited response. In contrast to the VRC01-class antibodies that are highly mutated, their unmutated forms do not engage HIV-1 envelope (Env) and do not display neutralizing activities. Hence, specifically modified Env-derived proteins have been designed to engage the unmutated forms of VRC01-class antibodies, and to activate the corresponding naïve B cells. Selected heterologous Env must then be used as boost immunogens to
