Grafton Police were called to the Advocate Aurora Health Hospital in Grafton on Wednesday, December 30, 2020, on a report that a former employee of the pharmacy had intentionally removed the vaccines from the refrigerated storage and left them to sit out overnight, rendering about 570 doses of the vaccine useless according to health professionals, a police spokesperson said. When the news of the destruction of doses first became public knowledge in late December, it was believed that the act was accidental. Upon further investigation, however, it was determined that it was intentional. Later, the former hospital worker admitted to intentionally removing the vaccine know that if not properly stored the vaccine would be ineffective.
