A pharmacist at a Wisconsin hospital has been arrested and accused of intentionally removing more than 500 doses of Moderna vaccine from refrigeration last week, knowing that the vaccines would be rendered useless and that the people receiving them would think they were protected against the virus when they were not, the police department in Grafton, Wisconsin, said Thursday. The pharmacist, a man whom the police did not name, was arrested on recommended charges of first degree recklessly endangering safety, adulterating a prescription drug and criminal damage to property, all felonies. It was not clear what his motive may have been. The Grafton police department is investigating the incident along with the FBI and the FDA. On Thursday, Jeff Bahr, the president of Aurora Health Care Medical Group where the pharmacist worked, said the hospital had consulted with Moderna and had been reassured that the spoiled vaccines would not harm the individuals who received them. He said the 57 people who received the vaccine had been notified.
