Universal flu vaccine may be available within two years, says scientist - The Guardian

Vaccine against all strains of virus hailed as major step in protecting against potentially devastating flu pandemic.

A universal flu vaccine that protects against all strains of the virus could be available in the next two years, according to a leading scientist.

Researchers have been working on universal flu vaccines for more than a decade, but the latest breakthrough, published in Science, is seen as a major step towards a jab that could help protect humans from a potentially devastating flu pandemic.

Seasonal flu vaccines, which protect against up to four strains of the virus, are updated every year to ensure they are a good match for flu viruses in circulation.
