No Medical History information was reported.    On 22-Feb-2022, the patient received dose of mRNA-1273 (Spikevax) (unknown route) 1 dosage form. On 22-Feb-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, 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), 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) 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 (Spikevax) (Unknown), the reporter did not provide any causality assessments.   No concomitant medications were reported.    The vial was moved to the fridge on 19 Jan 2022 and administered post 30 days from the initial storage at 2 degree Celsius to 8 degree Celsius.  It was unknown if the vial was undergone a previous temperature excursion. The storage condition at the time of the excursion was frozen storage/refrigerated storage. The state of the vaccine at the time of the excursion was partially thawed/liquid. The maximum temperature reached was 8°C. the total duration of the excursion refrigerated temps for max of 4 hours. The temperature fluctuations occurred as frozen-refrigerated and refrozen.   No treatment information was reported.
