Very few humans have gone up against bird flu. But we've all dealt with seasonal flu for years. Some of our immune systems ...
PHILADELPHIA— Prior exposures to specific types of seasonal influenza viruses promote cross-reactive immunity against the H5N1 avian influenza virus, according to new research from the Perelman ...
Following vaccination, H5 stalk antibodies increased slightly in older adults, but increased substantially in children. These antibodies bound to both the 2004 H5N1 virus and to the clade 2.3.4.4b ...

This means that people who were first exposed to H1N1 or H2N2 viruses before 1968 may have antibodies that can recognize the stalk of H5N1’s hemagglutinin protein. Since the stalk evolves more slowly ...
The lollipop "heads" of hemagglutinin proteins evolve more frequently while the "sticks" of the hemagglutinin lollipops, called stalks, don't evolve as quickly. Researchers tested blood samples from ...

However, hemagglutinin is constantly evolving. The “head” of the protein changes frequently, while the “stalk” remains more stable. Researchers tested blood samples from over 150 people ...
Current influenza vaccines primarily elicit antibodies that recognise hemagglutinin proteins and prevent them ... 150 people born between 1927 and 2016 for antibodies targeting the stalk proteins of ...
Their immunogen composition is revised biannually to optimally match the antigenic drift of the hemagglutinin of circulating influenza ... The substitutions V13I, I34V, L40I, and N44S are located in ...
A single amino acid in the stalk region of the H1N1pdm influenza virus HA protein ... Modulation of the pH stability of influenza virus hemagglutinin: a host cell adaptation strategy. Biophys J. 2016.
