mRNA flu vaccine offers immune protection against diverse strains

Article excerpt

Researchers at Washington University School of Medicine developed an experimental mRNA flu vaccine that trains the immune system to recognize a broader range of influenza viruses than traditional shots, according to a new study. The approach could provide stronger, longer-lasting protection by targeting multiple flu strains simultaneously rather than the limited set covered by annual vaccines. mRNA technology, already proven in COVID-19 vaccines, allows researchers to quickly reprogram immune responses. The findings suggest a potential path toward more durable flu protection, though the vaccine remains investigational and has not yet completed clinical trials.
