I'm not really sure what the end game was going to be, but the nurse was pilfering the vaccine from a distribution site in Detroit.

ClickOnDetroit reports that the nurse was working at the mass vaccination site at the TCF Convention Center in downtown Detroit. She was investigated after another nurse working the site saw her pocket two vials. The nurse was employed by an independent contractor.

“Our vaccines are stored in a secured location,” Detroit Chief Operating Officer Hakim Berry told ClickOnDetroit. “Even when we deliver they are with a security guard. We account for every syringe that we give out.”

I'm not really sure there's a black market for the vaccine, so I'm unsure what the end game was here. It was only two vials, so maybe she just wanted to vaccinate some younger relatives. At any rate, you can't take stuff that isn't yours, so off she goes.
