On an unknown date, the patient experienced POOR QUALITY PRODUCT ADMINISTERED (Vaccine administered to patient after more than 1 temperature excursion) and PRODUCT TEMPERATURE EXCURSION ISSUE (Vaccine 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.). At the time of the report, POOR QUALITY PRODUCT ADMINISTERED (Vaccine administered to patient after more than 1 temperature excursion) and PRODUCT TEMPERATURE EXCURSION ISSUE (Vaccine 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.) outcome was unknown.        For mRNA-1273 (Moderna COVID-19 Vaccine) (Unknown), the reporter did not provide any causality assessments.   No concomitant medications were reported.

On 14-Feb-2021, Underwent temperature excursion with temperature 32 degrees fahrenheit from 9am to 11am, 35 degrees fahrenheit from 2pm to 3pm. Beyond use date for the vial was reported as 10-Mar-2021.  On 16-Mar-2021, The vaccine with batch number 003B21A was moved to fridge, On 21-Mar-2021 vaccine moved to clinic, temperature was 34 degrees fahrenheit at 09:00 am, 32 degree fahrenheit at 10:00 am and 34 degree fahrenheit at 11:00 am. Beyond use date for the vial was reported as 15-Apr-2021.   Vial was in cooler storage and was not in frozen storage during high-pace COVID-19 vaccination at around 2021. Vials were only punctured right before administration. Vaccines were not frozen at time of administration. 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. Temperature recordings were taken using a traceable temperature monitor at every hour.  No treatment medications were reported.
