At the time of the report, POOR QUALITY PRODUCT ADMINISTERED (Doses administered after more than 1 temperature excursion during a period of 33 weeks on 2021) and PRODUCT TEMPERATURE EXCURSION ISSUE (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.

The HCP explained that each time a vial was put into a cooler, there was a period of time of 1 hour or 1 hour and a half approximately, when the temperature data logger registered 34 or 35 degree F. Vial with batch number 014M20A was stored on cooler 1, on 03-Mar-2021, excursion time at 9 am 51, at 10 am 34, at 11 am 44, at 12 am 46, at 1 pm 35, at 2 pm 36, at 3 pm 36 and at 4 pm 36. On 03-Mar-2021, excursion temperature at 9 am was 51, total doses given for the day was 200, condition of vaccine prior to vaccination was not frozen, vaccine was moved to fridge on 24-Feb-2021, vial was moved to clinic on 03-Mar-2021. 20 vial was moved to clinic.

Vaccine BUD date was 29-Apr-2021 for batch number 030B21A. Temperature recordings were taken by using a Fisherbrand traceable temperature monitor at every hour. The vials were only punctured right before administration and all doses were drawn from the vial due to high-pace clinic. After administration, the vial was returned to the freezer/refrigerator, or maintained at room temperature. No treatment information was provided.
