Protein Helps Immune System Mount “Instant Strike” Against Deadly Flu Viruses

Researchers at the University of Rochester have identified a protein in the immune system that appears to play a crucial role in protecting against deadly forms of influenza, and may be particularly important in protecting against emerging flu viruses like the avian flu. The researchers believe that a vaccine made with a live but weakened strain of flu virus – such as the inhaled flu vaccine introduced last year – may activate this part of the immune system and offer the best defense against avian flu.
