New Moderna Flu Shot for 50+ Boosts Protection, Speeds Up Vaccine Production
Regulators approved Moderna’s mFlusiva, a new mRNA flu vaccine, for adults 50 to 64 (fully) and 65+ (accelerated) after trials showed about 27% greater effectiveness than standard flu shots; the vaccine, available this fall, uses mRNA technology to allow faster production and potential yearly updates to match circulating strains, though side effects may be stronger than traditional vaccines; if you’re eligible, get whichever flu shot is available to start protection early in the season.
