Washington, Nov 26 (PTI) An experimental mRNA-based vaccine against all 20 known subtypes of influenza virus provided broad protection from otherwise lethal flu strains in initial tests, according to a study.

This could serve one day as a general preventative measure against future flu pandemics, the researchers from University of Pennsylvania, US, said.

According to the study, tests in animal models showed that the vaccine dramatically reduced signs of illness and protected from death, even when the animals were exposed to flu strains different from those used in making the vaccine.
