What is the correct storage temperature range for refrigerated vaccines?

The correct storage temperature range for refrigerated vaccines is 2°C to 8°C. This temperature range is essential for maintaining the efficacy and stability of vaccines, ensuring that they remain effective when administered to patients. Vaccines that are stored outside this range can experience decreased potency, which could compromise their effectiveness in preventing disease.

Maintaining this specific temperature range is critical as vaccines can be sensitive to heat or freezing, leading to potential loss of immunity. For example, some vaccines can become ineffective if exposed to temperatures below freezing, while others may degrade if kept at too high a temperature.

The other temperature ranges provided either fall below or exceed the recommended limits for vaccine storage, leading to a higher risk of reducing their effectiveness and safety. Proper storage practices are vital in immunization programs to ensure public health and safety.
