What is a cold chain system?
The cold chain is a set of rules and procedures that ensure the proper storage and distribution of vaccines to health services from the national to the local level. The cold chain is interconnected with refrigeration equipment that allows vaccines to be stored at recommended temperatures to maintain their potency.
Cold chains are common in the food and pharmaceutical industries and also in some chemical shipments. One common temperature range for a cold chain in pharmaceutical industries is 2 to 8 °C (36 to 46 °F), but the specific temperature (and time at temperature) tolerances depend on the actual product being shipped.
What are the types of cold chain?
There are two types of cold chain packaging systems: active and passive. Active systems consist of cold chain transport containers featuring advanced electric or battery-powered temperature controls. Active systems often have built-in cooling units or rely on dry ice as a coolant.21-Jul-2020
The objective of the Scheme of “Integrated Cold Chain and Value Addition Infrastructure” is to provide integrated cold chain and preservation infrastructure facilities, without any break, from the farm gate to the consumer. It covers creation of infrastructure facility along the entire supply chain viz.05-Sept-2022
Why is cold chain important?
Why is the cold chain important? The cold chain ensures that perishable products are safe and of high quality at the point of consumption. Failing to keep product at the correct temperatures can result in textural degradation, discoloring, bruising, and microbial growth.
What is a cold chain? A cold chain is a temperature-controlled supply chain comprising refrigerated production, storage and distribution facilities supported by equipment that can constantly maintain the required low-temperature range.
What are the elements of cold chain?
A cold chain can functionally be considered as the close interaction between three technologies:
The group launched the “Fresh by FAST” brand with the goal of offering an integration of refrigerated transport, cold storage for frozen and chilled temperatures, value-added services such as blast freezing, meat processing, packaging, and dry warehousing for related items that do not require refrigeration.28-Oct-2021
Who is responsible for cold chain management?
Maintaining the cold chain is important to ensure that effective and potent vaccines are administered to patients. Immunisation providers are responsible for ensuring all staff are trained in vaccine storage and cold chain management.
A cold chain failure occurs when vaccines are compromised or destroyed by freezing, being overheated or being exposed to direct sunlight/fluorescent light. Cold chain management practices nationwide are based on the National Guidelines.
What is cold chain introduction?
“Cold Chain” refers to the process used to maintain optimal conditions during the transport, storage, and handling of vaccines and biologics, starting at the manufacturer and ending with the administration to the patient or client.
Negligent staff, insufficient training, non-compliance with established protocols and inefficient use of equipment are some of the typical reasons cold chains fail. Some of the most common “human error” horror stories involve: Bad handling —damaged containers due to haphazard handling.13-Jun-2018
How do you store vaccines?
The vast majority of vaccines should be stored at between 2-8⁰C in a refrigerator, with a preferred average of 5⁰C, though some should remain frozen in a range between -15 to -50⁰C. Additionally, many should be protected from light and are packaged appropriately, as UV-light can damage them.
Steps in the Cold Supply Chain
How do you maintain a cold chain?
Cold chain is said to be properly maintained if and only if there is proper temperature monitoring (twice daily monitoring), proper review of vaccine vial monitoring to check exposure of vaccine to heat, undertaking shake test to check exposure of vaccine to freezing temperature, adherence to the first expiry first out 22-Jul-2021

Where does the cold chain start?
refrigerated facility
“If a cold chain is what you call the transport chain that goes from a laboratory to the field – where vaccines must be kept at a certain temperature from the moment they are produced, until they are administered in order for them to work – a reverse cold chain is the process of stool samples that need to be tested 16-Nov-2017
What is cold chain PDF?
Cold chain is a system of storing and transporting vaccines at recommended temperatures from the point of manufacture to the point of use.
Cold chain is the system of transporting and storing vaccine within the range of 2°C to 8°C (strive for 5°C - the midway point). A cold chain breach is the exposure of vaccines to light or temperature outside the recommended range of 2°C to 8°C, excluding fluctuations up to 12°C lasting less than 15 minutes.22-Mar-2022
What temp should vaccines be stored?
Store vaccines at the recommended temperatures IMMEDIATELY upon arrival. – Store refrigerated vaccines between 35°F and 46°F (2°C and 8°C). – Store frozen vaccines between -58°F and +5°F (-50°C and -15°C). Ensure vaccines are delivered when the facility is open.
