In a Facebook post, authorities said the vehicle was stolen Wednesday afternoon from the Strawberry Festival Grounds in Plant City, about 60 miles from Orlando.
The driver got out to ask for directions, left the car open, the keys in the starter and the engine running. The driver worked for CDR Maguire, a contractor that offered vaccination schedules and Covid-19 tests, according to a police incident report obtained by CNES subsidiary WESH-TV.
Authorities did not say how many doses of the vaccine were in the car. It is unclear if the suspect knew there were vaccines in the car.
The vaccine was intended for distribution at the Plant City Vaccination Center on the festival grounds, reports CNK subsidiary WKMG. The stolen vehicle is described as a 2018 gray Hyundai Accent with the Florida label NPJJ58.
Police have released surveillance video of a man who wants to interrogate them in connection with the theft.
Authorities are requesting that anyone with information about the theft contact the Plant City Police Department.
