Summary
The FDA has approved Moderna's MFLUSIVA, the first mRNA-based flu vaccine, for adults aged 50 and older. Unlike traditional flu vaccines, MFLUSIVA uses mRNA to instruct cells to create flu proteins, training the immune system without using a live virus. It has shown to be about 27% more effective than standard flu shots in preventing flu cases and is egg-free, though individuals with PEG allergies should consult their doctor.
