dose administered to patient after more than 1 temperature excursion; dose administered to patient after more than 1 temperature excursion/vial stored at cooler storage during high-pace COVID-19 vaccination clinic at the time of the excursion; This spontaneous case was reported by an other health care professional and describes the occurrence of POOR QUALITY PRODUCT ADMINISTERED (dose administered to patient after more than 1 temperature excursion/vial stored at cooler storage during high-pace COVID-19 vaccination clinic at the time of the excursion) and PRODUCT TEMPERATURE EXCURSION ISSUE (dose administered to patient after more than 1 temperature excursion) in a 50-year-old male patient who received mRNA-1273 (Moderna COVID-19 Vaccine) (batch nos. 031L20A and 031A21A) for COVID-19 vaccination.     No Medical History information was reported.   On 13-Feb-2021 at 1:38 PM, the patient received dose of mRNA-1273 (Moderna COVID-19 Vaccine) (unknown route) .5 milliliter. On 20-Mar-2021 at 1:50 PM, received dose of mRNA-1273 (Moderna COVID-19 Vaccine) (unknown route) dosage was changed to .5 milliliter. In 2021, the patient experienced POOR QUALITY PRODUCT ADMINISTERED (dose administered to patient after more than 1 temperature excursion/vial stored at cooler storage during high-pace COVID-19 vaccination clinic at the time of the excursion). On an unknown date, the patient experienced PRODUCT TEMPERATURE EXCURSION ISSUE (dose administered to patient after more than 1 temperature excursion). At the time of the report, POOR QUALITY PRODUCT ADMINISTERED (dose administered to patient after more than 1 temperature excursion/vial stored at cooler storage during high-pace COVID-19 vaccination clinic at the time of the excursion) and PRODUCT TEMPERATURE EXCURSION ISSUE (dose administered to patient after more than 1 temperature excursion) 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 50.49 for dose administered on 13-Feb-2021 and 50.58 for dose administered on 20-Mar-2021.  Concomitant products were not provided.  On 13-Jan-2021, 30 vials were moved to the clinic. On 09-Feb-2021, vaccines with batch number 031L20A were moved to the fridge. On 12-Feb-2021, three vials were moved to clinic. On the same day at 09 A.M, vials underwent temperature excursion with temperature 29 degrees Fahrenheit and between 10 A.M to 11 A.M vials underwent temperature excursion with temperature 35 degrees Fahrenheit. On 13-Feb-2021, at 09 A.M, vials underwent temperature excursion with temperature 32 degrees Fahrenheit. The vaccine beyond use date was reported as 10-Mar-2021.  On 09-Mar-2021, the vaccine with batch number 031A21A was moved to fridge. On 20-Mar-2021, 19 vials were moved to the clinic. On the same day at 09 A.M and 10 A.M, vials underwent temperature excursion with temperature of 34 and 37 degrees Fahrenheit respectively. The vaccine beyond use date was reported as 08-Apr-2021.  The condition of vaccine prior to vaccination was not frozen. It was reported that, the storage condition at the time of the excursion was cooler storage during high-pace COVID-19 vaccination clinic.  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.  It was reported that, the patient was administered with vaccine that experienced more than 1 temperature excursion during 33 weeks on 2021. The health care professional explained that each time a vial was put into a cooler, there was a period of 1 hour or 1 hour and a half approximately, when the temperature data logger registered 34 or 35 degree Fahrenheit.  Treatment medications were not reported.   This case was linked to MOD-2022-566976 (Patient Link).
