Researchers at Georgia State University and Emory University have developed an intranasal influenza vaccine using recombinant hemagglutinin (HA), a protein found on the surface of influenza viruses, as the antigen component of the vaccine.
They also created a two-dimensional nanomaterial (polyethyleneimine-functionalized graphene oxide nanoparticles) and found that it displayed potent adjuvant (immunoenhancing) effects on influenza vaccines delivered intranasally.
