On an unknown date, the patient experienced PRODUCT TEMPERATURE EXCURSION ISSUE (Patient received a vaccine that under went a temperature excursion) and NO ADVERSE EVENT (No adverse event). At the time of the report, PRODUCT TEMPERATURE EXCURSION ISSUE (Patient received a vaccine that under went a temperature excursion), POOR QUALITY PRODUCT ADMINISTERED (Patient received a vaccine that under went a temperature excursion) 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 PRODUCT TEMPERATURE EXCURSION ISSUE (Patient received a vaccine that under went a temperature excursion) and POOR QUALITY PRODUCT ADMINISTERED (Patient received a vaccine that under went a temperature excursion).    Concomitant medication list was not provided. Patients weight was reported as 33 (no unit reported).  Vaccine administration location was reported as LQ.  It was reported that, the vaccine underwent temperature excursion one in the freezer and one in the refrigerator.
