Immunization Module: The Cold Chain
Study Session 6 The Cold Chain
In this study session you will learn about the cold chain — the equipment and procedures that you will use to keep vaccines within the correct temperature range (between 2oC and 8oC), so that they remain in good condition. Vaccines should be stored carefully at all times, beginning at the factory where they are manufactured and at every stage until the moment they are given to children and mothers. Excess heat or cold will reduce the vaccine potency (strength), increasing the risk that recipients will not be protected against vaccine-preventable diseases.
The cold chain has three main components: equipment for vaccine transport and storage, well-trained personnel, and efficient management procedures. In this study session, and the next two sessions, you will learn how all three components are required to ensure that vaccines are transported and stored safely.
