Abstract: Provided are modified influenza virus subtype 2 neuraminidase molecules lacking all or substantially all of the stalk region that form active, soluble tetrameric neuraminidase when expressed in host cells and vaccine compositions comprising the tetrameric neuraminidase or a nucleic acid encoding the modified monomeric influenza virus subtype 2 neuraminidase molecules that forms tetrameric NA when expressed in a cell. Also provided are methods of using the vaccine compositions to vaccinate or immunize a subject against influenza virus.

Abstract: The present invention provides, among other things, compositions and methods for analyzing the expression and conformation of engineered influenza hemagglutinin In particular, the present invention provides methods of screening in silico designed HA antigens using neutralizing antibody panels specific to conserved epitopes. In some embodiments, the HAs are down selected for inclusion in universal influenza vaccines based upon their binding to neutralizing antibody panels in immunostaining assays.
