Vaccine for flu to be tested on humans

Adam9 writes: British scientists are on the verge of producing a revolutionary flu vaccine that works against all major types of the disease. Described as the 'holy grail' of flu vaccines, it would protect against all strains of influenza A — the virus behind both bird flu and the nastiest outbreaks of winter flu. Just a couple of injections could give long-lasting immunity — unlike the current vaccine which has to be given every year.
