摘要: Vaccines that elicit broadly protective anti-influenza antibodies. The vaccines comprise nanoparticles that display HA trimers from Group 2 influenza virus on their surface. The nanoparticles are fusion proteins comprising a monomeric subunit (e.g., ferritin) joined to stabilized stem regions of Group 2 influenza virus HA proteins. The fusion proteins self-assemble to form the HA-displaying nanoparticles. Also provided are fusion proteins, and nucleic acid molecules encoding such proteins, and assays using nanoparticles of the invention to detect anti-influenza antibodies.
