Vaccines were not frozen at time of administration. It was reported that each time a vial was put into a cooler, sometimes there was a period of 1 hour or 1 hour and a half approximately, when temperature data logger registered a temperature of 34- or 35-degree Fahrenheit. Temperature recordings were taken using a Fisherbrand traceable temperature monitor at every hour. No treatment medications were reported. This case was linked to MOD-2022-566976 (Patient Link).
