How often should the refrigerator temperature be monitored for vaccine storage?

Vaccines are sensitive to temperature variations, which can significantly affect their efficacy and safety. Therefore, the correct practice is to monitor the refrigerator temperature twice daily. This frequent monitoring helps ensure that the storage conditions remain within the required range, typically between 2°C to 8°C (36°F to 46°F), which is crucial for maintaining the potency of vaccines.

By checking the temperature two times a day, health care providers can detect and respond quickly to any deviations that could compromise vaccine integrity. This approach is consistent with guidelines from public health organizations that emphasize the importance of maintaining consistent storage temperatures for immunobiologics. Regular temperature checks also facilitate proper documentation, which is essential for accountability and quality assurance in vaccine management.
