This spontaneous case was reported by an other health care professional and describes the occurrence of PRODUCT TEMPERATURE EXCURSION ISSUE (Doses administered after more than 1 temperature excursion during a period of 33 weeks on 2021) and POOR QUALITY PRODUCT ADMINISTERED (Doses administered after more than 1 temperature excursion during a period of 33 weeks on 2021) in a 47-year-old male patient who received mRNA-1273 (Moderna COVID-19 Vaccine) (batch nos. 019B21A and 014M20A) for COVID-19 vaccination. No Medical History information was reported. On 02-Mar-2021 at 4:03 PM, the patient received dose of mRNA-1273 (Moderna COVID-19 Vaccine) (unknown route) .5 milliliter. On 30-Mar-2021 at 4:07 PM, received dose of mRNA-1273 (Moderna COVID-19 Vaccine) (unknown route) dosage was changed to .5 milliliter. In March 2021, the patient experienced POOR QUALITY PRODUCT ADMINISTERED (Doses administered after more than 1 temperature excursion during a period of 33 weeks on 2021). On an unknown date, the patient experienced PRODUCT TEMPERATURE EXCURSION ISSUE (Doses administered after more than 1 temperature excursion during a period of 33 weeks on 2021). At the time of the report, PRODUCT TEMPERATURE EXCURSION ISSUE (Doses administered after more than 1 temperature excursion during a period of 33 weeks on 2021) and POOR QUALITY PRODUCT ADMINISTERED (Doses administered after more than 1 temperature excursion during a period of 33 weeks on 2021) outcome was unknown. For mRNA-1273 (Moderna COVID-19 Vaccine) (Unknown), the reporter did not provide any causality assessments. Age of patient was reported as 47.89 years for batch number 014M20A and 47.96 for batch number 019B21A. No concomitant medications were reported. Batch number 014M20A underwent temperature excursion on 02-Mar-2021 with temperature 27 degrees Fahrenheit at 09:00 AM, 29 degrees Fahrenheit at 10:00 AM, 32 degrees Fahrenheit at 11:00 AM, 33 degrees Fahrenheit at 12:00 PM, 35 degrees Fahrenheit at 02:00 PM and 36 degrees Fahrenheit at 03:00 PM. This vial was moved to fridge on 24-Feb-2021 and beyond use date for the vial was reported as 26-Mar-2021. Product moved to clinic on 02-Mar-2021. 16 vials were sent to clinic. Condition of vaccine prior to administration was not frozen. Batch number 019B21A underwent temperature excursion on 30-Mar-2021 with temperature 33 degrees Fahrenheit at 09:00 AM. This vial was moved to fridge on 23-Mar-2021 and beyond use date for the vial was reported as 22-Apr-2021. Product moved to clinic on 30-Mar-2021. 03 vials were sent to clinic. Condition of vaccine prior to administration was not frozen. The vials were only punctured right before administration and all doses were drawn from the vial due to high-pace clinic. Temperature recordings were taken using a Fisherbrand traceable temperature monitor at every hour. After administration, the vial was returned to the freezer/refrigerator, or maintained at room temperature. It was reported that the patient was administered with vaccines that experienced more than 1 temperature excursion during 33 weeks in 2021. The HCP explained that each time a vial was put into a cooler, there was a period of 1 hour or 1 and half hour approximately, when the temperature data logger registered 34 or 35 degree F. Treatment medications were not reported.
