In 2263, when Leonard "Bones" McCoy injects you with the vaccine for Melvaran Mud Fleas, you'd better follow his orders. His Starfleet Medical-issued badge gives him the authority to follow whatever course of action he deems medically necessary to care for his patient.
This screen-accurate badge from the 2009 Star Trek Movie is worn by medical personnel on board every Starfleet vessel, including the famous USS Enterprise. This pin-backed insignia will hold fast to your jacket, shirt, or duty uniform!
So whether you're going blind in your left eye, or you're suffering from a case of numb-tongue, don't worry! He can fix that!
