Scientists have designed a new generation of universal flu vaccines that protects against majority of the known viral strains and help prevent future global pandemics that could kill millions.
The researchers devised two universal vaccines . one can protect against up to 88 percent of known flu strains worldwide in a single shot , spelling the end of the winter flu season.
Another vaccine covers 95 percent of known US influenza strains , they said.
The components of this vaccine would be short flu virus fragments called "epitopes" that are already known to be recognised by the immune system .
The study was published in the journal Bioinformatics.
