Researchers test mRNA technology for universal flu vaccine

(VOVWORLD) - An experimental vaccine provided broad protection against all 20 known influenza A and B virus subtypes in initial tests in mice and ferrets, potentially opening a pathway to a universal flu shot that might help prevent future pandemics, according to a US study published on Thursday.

The two-dose vaccine employs the same mRNA technology used in the COVID-19 shots developed by Pfizer with BioNTech, and by Moderna.

A universal vaccine would not mean an end to flu seasons, but would replace the guess work that goes into developing annual shots months ahead of flu season each year.

"The idea here is to have a vaccine that will give people a baseline level of immune memory to diverse flu strains, so that there will be far less disease and death when the next flu pandemic occurs," study leader Scott Hensley at the University of Pennsylvania said in a statement.
