What does cold chain mean?
Delivering vaccines to all corners of the world is a complex undertaking. It takes a chain of precisely coordinated events in temperature-controlled environments to store, manage and transport these life-saving products. This is called a cold chain.
What is the Cold Chain Management Process? The cold chain management process includes the storage, packaging, tracking, transportation, customs clearance, product management, and delivery of products safely and securely.15-Nov-2021
What is 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 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 is the first step in the cold chain?
Steps in the Cold Supply Chain
Unpack vaccines from the transport container and store them in their packaging regardless of their bulkiness. Removing vaccines from the original packaging exposes vaccines to room temperature and light. Check the temperature to ensure the vaccines have not been exposed to temperatures above 35°F or below 32°F.
What are the key elements of cold chain?
The main elements of a cold chain involve:
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
What is active cold chain?
An active cold chain for pharmaceutical transport means that pharmaceuticals are transported in active temperature-controlled containers. Active containers keep an exact temperature inside the container and can adjust for ambient temperatures.07-May-2019
Cold chain packaging systems are designed to maintain sensitive products at the correct temperature (i.e. cold, warm, frozen, etc). There are three basic types of cold chain packaging systems available: active, passive and hybrid.05-Sept-2022
Why do we need cold chains?
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.
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.
Who is responsible for cold chain?
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.
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 long can vaccines be out of cold chain?
No more than two weeks of vaccine stock should be ordered in advance of use to prevent excess vaccine loss in the event of a cold-chain breach.
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.
Which vaccines should be frozen?
Varicella vaccine (A) and MMRV vaccine (C) MUST be stored in the freezer.
Never place freeze-sensitive vaccines in direct contact with the ice packs. Surround them with OPV/BCG/JE vaccines. Keep a thermometer in the cold box. Place two rows of conditioned ice packs above the vaccine vials.
What is ILR in cold chain?
Ice-lined refrigerator (ILR)

What is cold chain PDF?
The cold chain. • The cold chain is the system used for keeping. and distributing vaccines and other Biologicalsin good conditions. • It consists of a series of storage and transport. links, all designed to keep vaccines within an acceptable range until it reaches the user.
