New mRNA flu vaccine offers broader protection against influenza strains
In a 75-person trial, the investigational vaccine produced more flu-specific antibodies and memory B cells than the standard shot, researchers said.

New mRNA flu vaccine offers broader protection against influenza strains
A new study led by researchers at Washington University School of Medicine in St. Louis has found that an investigational mRNA influenza vaccine helps the immune system recognize a wider range of influenza viruses than today's standard flu shot, offering stronger and potentially longer-lasting protection.
mRNA Flu Vaccine Shows Stronger, Longer-Lasting Immune Response
Flu shots reduce hospitalizations and deaths for the roughly one billion people worldwide that get the flu each year. But they are less effective when the vaccine strains don’t closely match the viruses circulating in the community. Today’s vaccines are made months in advance of the flu season due to a long manufacturing process. When projections are off, strain mismatch can reduce the efficacy of the flu vaccines from about 60% (in a good year)…
