An advisory committee to the U.S. Food and Drug Administration (FDA) unanimously recommended approving Moderna's new mRNA-based flu vaccine, mFlusiva, for adults aged 50 and older. The panel concluded that the vaccine's benefits outweigh its risks after reviewing studies showing it reduced flu cases by about 27% in a large trial of people age 50 and older compared to another routinely used vaccine brand, as reported by Los Angeles Times.
Key Takeaways
An FDA panel unanimously recommended approving Moderna's mRNA-based flu vaccine for adults aged 50 and older. The vaccine showed promising results in reducing flu cases and generating strong immune responses, with the FDA expected to make a final decision by early August. If approved, it would be the first seasonal flu shot using mRNA technology in the U.S., potentially improving preparedness for emerging strains.

The FDA is evaluating Moderna's shot ahead of the winter flu season. The company seeks full approval for use in people ages 50 to 64 and authorization for those 65 and older while it conducts additional testing. According to PBS, the vaccine generated a strong protective immune response in a smaller study of people 65 and older compared with a high-dose flu vaccine already recommended for that age group.
The mRNA technology, which was key to ending the COVID-19 pandemic, allows for faster manufacturing than traditional vaccines. Experts believe this could help if the flu virus mutates in a way that requires new doses to match. Dr. Flor Munoz-Rivas of Texas Children's Hospital noted that having this technology available puts us in a better position to be prepared for emerging strains in the future.
The FDA will consider the panel's recommendation and make a final decision by early August, as reported by Reuters. Moderna plans to conduct further studies if approved, including a trial with 400,000 people aged 65 and older. The vaccine showed no major safety issues but caused temporary reactions such as injection-site pain, fever, headache, tiredness, and aches.
