How often should temperature logs be checked for vaccine refrigerators?

Temperature logs for vaccine refrigerators should be checked at least twice daily to ensure that vaccines are stored within the recommended temperature ranges. This frequency is essential because even minor fluctuations in temperature can compromise the efficacy of vaccines.

By checking the logs twice a day, personnel can promptly identify and address any potential temperature excursions, which could impact the stability and effectiveness of the vaccines. Regular monitoring helps maintain a consistent environment necessary for preserving the vaccines' integrity, ultimately safeguarding patient health and ensuring vaccination campaigns are effective.

The other options suggest less frequent checks, which may not provide adequate oversight to prevent temperature deviations that can occur during the day or night, risking the quality of the stored vaccines.
