The new universal flu vaccine which will only need to be administered just once has been by researchers. The vaccine has been found to be effective against a number of different types of flu virus, including avian flu and swine flu strains.

FLU-v is the first of a new class of breakthrough T Cell vaccines. These are anticipated to be effective against the highly mutagenic influenza virus.

Scientists are planning a large-scale clinical trial and hope to have a vaccine available for widespread use in three to five years time. If trials are successful, it would be offered to the UK’s NHS.
