MILWAUKEE (AP) – Clinicians had to discard about 500 doses of the Moderna vaccine after bottles were kept cool for too long at Aurora Medical Center in Grafton.
Lawyer Aurora Health’s officials said someone took 50 vials out of the refrigerator to gain access to other items and could not return them overnight Friday.
Each vial contains 10 doses of vaccine. According to an internal investigation, the failure is an ‘unintentional human error’.
Clinicians were still able to administer some of the vaccine from the vials within the permitted window after cooling. Once the vaccine has been thawed, it cannot be frozen again.
