Vaccination units should be equipped with cold chain facilities and equipment are

1. Cold stores or refrigerators for storing and protecting vaccines, the temperature of which must be maintained between +2 degrees and +8 degrees.

2, refrigerated trucks, used for remote transportation of vaccines, to maintain a low temperature during transportation.

3. Ice boxes or ice packs, which can be used for short-distance transportation of vaccines, but the ice packs need to be replaced periodically to keep the temperature low.
