The mechanisms behind seasonal influenza outbreaks are unclear, but understanding these patterns could help health officials wrangle with a notoriously mercurial medical specter caused by a rapidly mutating virus.

Using virus histochemical analysis, the investigators looked at the pattern of attachment of two genetically engineered emerging H7 viruses (containing the hemagglutinin (HA) of either influenza virus A / Shanghai / 1 / 13 or A / Anhui / 1 / 13) to fixed human respiratory tract tissues and compared the findings to attachment patterns seen with human influenza viruses with high transmissibility but low virulence (seasonal H3N2 and pandemic H1N1) and highly pathogenic avian influenza (HPAI) viruses with low transmissibility and high virulence (H5N1 and H7N7).

The never - before - described virus did not involve the novel H1N1 but instead picked up the surface genes from the seasonal human H1N1 virus that has long infected humans and combined them with what's known as the triple - reassortant swine influenza.

In additional experiments, the scientists found that participants who had significant antibody responses did not necessarily also have significant immune system T cell responses to avian viruses, indicating that these two arms of immunity can be independently boosted after vaccination or infection; that individuals who reported receiving seasonal influenza vaccination had significantly higher antibodies to the avian H4, H5, H6, and H8 subtypes; and that participants with exposure to poultry had significantly higher antibody responses to the H7 subtype, but to none of the other subtypes tested.

Each year, the U.S. Food and Drug Administration, in collaboration with the Centers for Disease Control and Prevention and the World Health Organization, decides which strains of influenza virus to include in the seasonal flu vaccine.
