have designed influenza vaccine candidates based on group 2 influenza hemagglutinin (HA) proteins. These group 2 HA proteins were engineered to remove the highly variable head region and stabilize ...

Prior exposures to specific types of seasonal influenza viruses promote cross-reactive immunity against the H5N1 avian ...

H5N1 influenza is evolving rapidly, weakening the effectiveness of existing antibodies and increasing its potential threat to ...

New computational modeling of avian influenza variants' immunoprotein interactions—developed by a research team at the ...

The isolation of influenza virus 80 years ago in 1933 ... for viruses isolated during the 1900s); The subtype [16 possible hemagglutinin and 9 possible neuraminidase subtypes].

Early flu exposure helps immunity against H5N1 infection, with older adults having stronger antibody responses.

Influenza strains are referred to by a shorthand code, H5N1 for example, that describes which flavors of two particular surface proteins it carries. The H (sometimes HA), is hemagglutinin, a ...

Current nomenclature for influenza viruses (WHO 1980 ... for viruses isolated during the 1900s); The subtype [16 possible hemagglutinin and 9 possible neuraminidase subtypes].

Avian influenza viruses are classified based on a combination of two groups of proteins: the hemagglutinin or 'H' proteins, of which there are 16 (H1-H16) and neuraminidase or 'N' proteins ...
