What is the correct storage temperature range for most vaccines?

The correct storage temperature range for most vaccines is 2°C to 8°C (36°F to 46°F). This temperature range is crucial because it helps maintain the efficacy and stability of vaccines. Vaccines contain sensitive biological components that can degrade if exposed to temperatures outside this range, potentially rendering them ineffective.

Storage at 2°C to 8°C allows for optimal preservation of the vaccine's potency, ensuring that when administered, the vaccine will elicit the desired immune response. Health organizations, such as the World Health Organization (WHO) and the Centers for Disease Control and Prevention (CDC), provide guidelines emphasizing this temperature range to ensure the safety and effectiveness of vaccines during storage and transportation.

Other temperature ranges mentioned do not align with standard vaccine storage protocols. For instance, temperatures below freezing or above the recommended range could harm the vaccines, leading to a loss of efficacy. Therefore, adhering to the specified storage temperature is essential for vaccine integrity and public health safety.
