Is there a vaccine effective against H5N1 (avian influenza) in humans?
No. Currently available vaccines will not protect against disease caused by the H5N1 strain in humans. World health organisation is urgently working together with laboratories in the WHO Global Influenza Surveillance Network to develop a prototype H5N1 virus for use by leading vaccine manufacturers.
Various organisations worldwide are working towards producing a vaccine against avian flu (H5N1) including the National Institute for Biological Standards and Control (NIBSC) in the UK. Some organisations and some manufacturers have produced candidate vaccines which can be evaluated in humans. However mass production of a vaccine will not take place unless there is evidence of efficient spread between humans.
