Roughly 500 doses of coronavirus vaccine that had to be discarded were deliberately spoiled by an employee, a Wisconsin health system said Wednesday.

The spoiled doses were reported on Saturday and accidentally left out overnight by an employee at Aurora Medical Center in Grafton, Wis., about 23 miles north of Milwaukee.

Aurora said the employee involved "acknowledged that they intentionally removed the vaccine from refrigeration," according to a statement on Wednesday.
