What happened

Food and Drug Administration has approved Moderna's flu vaccine for people aged 50 and older, the company said on Wednesday, marking the first approval of a messenger RNA-based vaccine for seasonal flu.

Why it matters

The shot, mFlusiva, was given a traditional approval for adults aged 50 to 64, and an accelerated approval for those 65 years and older.

Common ground

Moderna has agreed to run an additional study and submit more data in adults 65 and older to confirm the vaccine's benefit in that age group.

Perspective signals

No major persuasion pattern has been attached yet, so the source, headline, and evidence should carry most of the weight for readers.
