  1. Vaccines are always transported as refrigerated cargo directly by air from the manufacturer to the country where they will be used when delivered. Once they land, they are stored in cold rooms before being distributed to regional and sub-regional cold storage facilities by refrigerated vehicle. Health workers carry vaccines in refrigerators and vaccine carriers by car, motorcycle, donkey, camel or on foot from storage facilities to villages, to vaccinate every child, even in the most remote villages.Our temperature logger for refrigerator can help to monitor temperature in every step.

  2. Storage and transport equipment such as cold rooms, refrigerators, freezers, cold boxes and vaccine carriers must comply with performance standards.  Any temperature abuse, either above or below the safe limit, can result in compromised efficiency or even total loss of products.
