In contrast, the immunogenically subdominant stem region of HA is highly conserved and recognized by antibodies capable of binding multiple HA subtypes. Here we report the structure-based development of an H1 HA stem-only immunogen that confers heterosubtypic protection in mice and ferrets. Six iterative cycles of structure-based design (Gen1-Gen6) yielded successive H1 HA stabilized-stem (HA-SS) immunogens that lack the immunodominant head domain. Antigenic characterization, determination of two HA-SS crystal structures in complex with stem-specific monoclonal antibodies and cryo-electron microscopy analysis of HA-SS on ferritin nanoparticles (H1-SS-np) confirmed the preservation of key structural elements. Vaccination of mice and ferrets with H1-SS-np elicited broadly cross-reactive antibodies that completely protected mice and partially protected ferrets against lethal heterosubtypic H5N1 influenza virus challenge despite the absence of detectable H5N1 neutralizing activity in vitro. Passive transfer of immunoglobulin from H1-SS-np-immunized mice to naive mice conferred protection against H5N1 challenge, indicating that vaccine-elicited HA stem-specific antibodies can protect against diverse group 1 influenza strains.
