Vaccine Cold Chain
The vaccine cold chain is the process of keeping vaccines at the correct temperature from manufacturing to administration. This is essential because many vaccines can lose effectiveness if they get too hot or too cold. The cold chain involves refrigerated storage, insulated containers, and temperature monitoring tools to ensure vaccines stay safe and potent. Maintaining this chain prevents spoilage, ensuring that when vaccines reach people, they are effective at building immunity against diseases. Proper cold chain management is vital for public health, especially in remote or resource-limited areas.
