Australian researchers have identified immune cells which could fight all strains of influenza virus a finding that raises hope for a universal vaccine which does not need to be updated annually. The team from the Peter Doherty Institute for Infection and Immunity have identified immune cells called killer T cells that can fight all influenza viruses - A B and C. It is a paradigm-shifting discovery which could lead to the development of a world-first universal one-shot flu vaccine that does not need to be updated annually the researchers said. Influenza viruses continuously mutate to evade recognition by our immune
