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; Frozen vials, removed and transported at refrigerated temp, re-frozen at ti me of arrival; 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; This spontaneous case was reported by a nurse and describes the occurrence of 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), 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) in a  patient of an unknown age and gender who received mRNA-1273 (Moderna COVID-19 Vaccine) (batch no. 033F21A) for COVID-19 vaccination.     No Medical History information was reported.    On 06-Jan-2022, the patient received dose of mRNA-1273 (Moderna COVID-19 Vaccine) (unknown route) 1 dosage form. On 06-Jan-2022, 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). At the time of the report, 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), 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) outcome was unknown.        For mRNA-1273 (Moderna COVID-19 Vaccine) (Unknown), the reporter did not provide any causality assessments.   No concomitant medications were reported. No treatment information was reported. The facility thought that the vials were received frozen from Moderna, so they have been unpacking them and putting them back into the facility freezer. 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.The vial was moved to the fridge on 01-Dec-2021 and administered post 30 days from the initial storage at 2C to 8C.   This case was linked to MOD-2022-496015 (Patient Link).
