received the Monovalent Moderna COVID-19 vaccine instead of the Bivalent Moderna COVID-19 vaccine; Patients received the Monovalent Moderna COVID-19 vaccine instead of the Bivalent Moderna COVID-19 vaccine; Patients received the vaccination after a temperature excursion/ Facility had a temperature excursion in the freezer; No adverse event; This spontaneous case was reported by a nurse and describes the occurrence of WRONG PRODUCT ADMINISTERED (received the Monovalent Moderna COVID-19 vaccine instead of the Bivalent Moderna COVID-19 vaccine), WRONG PRODUCT ADMINISTERED (Patients received the Monovalent Moderna COVID-19 vaccine instead of the Bivalent Moderna COVID-19 vaccine), PRODUCT TEMPERATURE EXCURSION ISSUE (Patients received the vaccination after a temperature excursion/ Facility had a temperature excursion in the freezer) and NO ADVERSE EVENT (No adverse event) in a female patient of an unknown age who received mRNA-1273 (Moderna COVID-19 Vaccine) (batch no. AR5186C) for COVID-19 vaccination.     No Medical History information was reported.    On an unknown date, the patient received dose of mRNA-1273 (Moderna COVID-19 Vaccine) (unknown route) 1 dosage form. On an unknown date, the patient experienced WRONG PRODUCT ADMINISTERED (received the Monovalent Moderna COVID-19 vaccine instead of the Bivalent Moderna COVID-19 vaccine), WRONG PRODUCT ADMINISTERED (Patients received the Monovalent Moderna COVID-19 vaccine instead of the Bivalent Moderna COVID-19 vaccine), PRODUCT TEMPERATURE EXCURSION ISSUE (Patients received the vaccination after a temperature excursion/ Facility had a temperature excursion in the freezer) and NO ADVERSE EVENT (No adverse event). At the time of the report, WRONG PRODUCT ADMINISTERED (received the Monovalent Moderna COVID-19 vaccine instead of the Bivalent Moderna COVID-19 vaccine), WRONG PRODUCT ADMINISTERED (Patients received the Monovalent Moderna COVID-19 vaccine instead of the Bivalent Moderna COVID-19 vaccine), PRODUCT TEMPERATURE EXCURSION ISSUE (Patients received the vaccination after a temperature excursion/ Facility had a temperature excursion in the freezer) and NO ADVERSE EVENT (No adverse event) outcome was unknown.        For mRNA-1273 (Moderna COVID-19 Vaccine) (Unknown), the reporter considered NO ADVERSE EVENT (No adverse event) to be not related. No further causality assessments were provided for WRONG PRODUCT ADMINISTERED (received the Monovalent Moderna COVID-19 vaccine instead of the Bivalent Moderna COVID-19 vaccine), WRONG PRODUCT ADMINISTERED (Patients received the Monovalent Moderna COVID-19 vaccine instead of the Bivalent Moderna COVID-19 vaccine) and PRODUCT TEMPERATURE EXCURSION ISSUE (Patients received the vaccination after a temperature excursion/ Facility had a temperature excursion in the freezer).    Concomitant medications were not reported.  The patient received booster dose of Moderna Monovalent vaccine.  The facility had a temperature excursion in the freezer. They had an inspection and had seen that their DDL was not recording the temperatures. The storage condition was reported as frozen at the time of the excursion. The vials were within unbroken cartons and were of the sizes 2.5 ml and 5.5 ml..  Patients received the 611-year-old Moderna COVID-19 vaccine instead of the 12+ Moderna COVID-19 vaccine  Because only manual recording was done twice a day, the maximum and minimum temperatures reached by the vials were unknown.  The excursion duration was unknown. The vaccine was returned to the freezer.   The visual inspection showed the vaccine state as still frozen.  The vial underwent temperature excursion for the first time.  Treatment medications were not reported.
