On an unknown date, the patient experienced PRODUCT TEMPERATURE EXCURSION ISSUE (Vial temperature maintained 2-8 degrees Celsius for 10-15 minutes before thawing/Dose administered after temperature excursion) and PRODUCT STORAGE ERROR (Transport occurred on 07Apr2022 and dose was administered on 09May2022/Returned to the freezer). At the time of the report, EXPIRED PRODUCT ADMINISTERED (Vaccine transported on 07Apr2022, Previously frozen at the previous facility and dose administered after 30-day use by date), PRODUCT TEMPERATURE EXCURSION ISSUE (Vial temperature maintained 2-8 degrees Celsius for 10-15 minutes before thawing/Dose administered after temperature excursion), PRODUCT STORAGE ERROR (Transport occurred on 07Apr2022 and dose was administered on 09May2022/Returned to the freezer) and INAPPROPRIATE SCHEDULE OF PRODUCT ADMINISTRATION (First dose received on 15-Oct-2021 and Second dose received on 09 May 2022) outcome was unknown. For mRNA-1273 (Spikevax) (Intramuscular), the reporter did not provide any causality assessments. Concomitant  Blood pressure, Diabetes, Over-the-counter medications were provided. Reporter stated that during the transport the vial temperature maintained 2-8 degrees C for 10-15 minutes.
