In the world of monitoring coronavirus vaccines during storage and handling, there are three general temperature profiles. These profiles include refrigerated 2°C to 8°C (36°F to 46°F), frozen -25°C to -15°C (-13°F to 5°F), and ultra-low temperature -80°C to -60°C (-112°F to -76°F). A data logger is used to provide complete monitoring and a record of temperatures of which vaccines have been exposed. The logger enables you to ensure that your vaccines’ potency is preserved and that they have not experienced any temperature excursions.
