Health news today spans both medical progress and sobering reminders of vulnerability. The FDA has approved Moderna’s first mRNA flu vaccine for adults 50 and older, a milestone that extends the technology beyond COVID-19 and could reshape seasonal vaccination if uptake is strong this fall. At the same time, new research from England and Wales warns that e-scooter riders face sharply higher risks of traumatic injury, especially brain injury, than cyclists or motorcyclists, underscoring how quickly new forms of transport can outpace safety habits like helmet use. And there was a deeply personal loss in the online health community: TikTok creator Sydney Towle has died at 26 after documenting her battle with rare bile duct cancer, turning her illness into a source of connection and visibility for young people confronting serious disease. Together, the day’s stories capture health as both innovation and human fragility.
