This is why we can't have nice things.

Authorities arrested a suburban Milwaukee pharmacist Thursday suspected of deliberately ruining hundreds of doses of coronavirus vaccine by removing it from refrigeration for two nights.

The Grafton Police Department said the former Advocate Aurora Health pharmacist was arrested on suspicion of reckless endangerment, adulterating a prescription drug and criminal damage to property. The department said in a news release that he was in jail. Police did not identify the pharmacist, saying he has not yet been formally charged.

His motive remains unclear. Police said that detectives believe he knew the spoiled doses would be useless and people who received them would mistakenly think they’d been vaccinated when they hadn’t.

Advocate Aurora Health Care Chief Medical Group Officer Jeff Bahr told reporters during a teleconference Thursday afternoon that the pharmacist deliberately removed 57 vials that held hundreds of doses of the Moderna vaccine from refrigeration at a Grafton medical center overnight on Dec. 24 into Dec. 25, returned them, then left them out again on the night of Dec. 25 into Saturday. The vials contained enough doses to inoculate 570 people.

A pharmacy technician discovered the vials outside the refrigerator on Saturday morning. Bahr said the pharmacist initially said that he had removed the vaccine to access other items in the refrigerator and had inadvertently failed to replace it.

The Moderna vaccine is still viable for 12 hours outside refrigeration, so workers used the vaccine to inoculate 57 people before discarding the rest. Police said the discarded doses were worth between $8,000 and $11,000.
