No Medical History information was reported.    On 15-Oct-2021, the patient received dose of mRNA-1273 (Moderna COVID-19 Vaccine) (unknown route) 1 dosage form. On 15-Oct-2021, the patient experienced EXPIRED PRODUCT ADMINISTERED (They just recently found out that the vials are received in refrigerated temperatures and not frozen/ They have been accidentally administering refrozen vials to their patients). On an unknown date, the patient experienced PRODUCT STORAGE ERROR (They just recently found out that the vials are received in refrigerated temperatures and not frozen/ They have been accidentally administering refrozen vials to their patients) and PRODUCT TEMPERATURE EXCURSION ISSUE (Frozen vials, removed and transported at refrigerated temp, re-frozen at ti me of arrival).
