Cold Chain Management of Vaccines refers to the systematic process of storing and transporting vaccines within a recommended temperature range—typically between 2°C and 8°C—from the point of manufacture to the point of administration. This temperature-controlled supply chain is critical to maintaining the potency and effectiveness of vaccines, which are highly sensitive to heat, light, and freezing. Effective cold chain management involves the use of specialized equipment such as refrigerated vehicles, cold boxes, data loggers, and temperature monitors, along with strict protocols for handling, storage, and transportation. It plays a vital role in immunization programs worldwide, ensuring vaccines remain safe and effective to protect public health.
