Scientists say they have made a breakthrough in designing a vaccine against all 20 known types of flu.

It uses the same messenger ribonucleic acid (mRNA) technology as proven Covid vaccines.

Influenza mutates and the current annual vaccine is updated to ensure the best possible match with the type of flu in circulation, but it would probably not protect against new types of pandemic.

The new vaccine triggered high levels of antibodies, in tests in ferrets and mice, that could fight off a wide range.
