What is cold chain and its components?
The cold chain has three main components, each of which must combine to ensure safe vaccine transport and storage: transport and storage equipment. trained personnel. efficient management procedures.
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
Which cold chain instrument is used at PHC level?
At the PHC level, DF is used only for preparation of ice packs. At the district headquarters, DFs have been supplied for storage of recommended vaccines such as OPV and preparation of ice packs.
Dry ice is actually a staple of cold chain logistics, and is frequently used to deliver perishables to consumers. It maintains a safe temperature, and it lasts for a very long time. Gel packs are also popular, particularly for items that shouldn't get too hot but don't need to be frozen.28-May-2019
What is the temperature of cold chain?
The “Cold Chain” is the system of transporting and storing vaccines within the temperature range of 35°F (2°C) to 45°F (8°C). The cold chain begins when vaccine is manufactured, moves through to the state distribution center and ends with the local immunization provider at the time of administration.
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.
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
Cold chain packaging is a system of packaging and shipping goods maintaining a consistent temperature from manufacture to final destination.12-Jul-2017
WHAT IS Pharma cold chain?
Pharmaceutical Cold Chain Logistics “Cold chain products” refer to medicines that must be kept within a precise temperature range. These products include vaccines, biologics, oncology treatments, some types of insulin and other medicines.18-Sept-2020
Oral polio vac- cine (OPV) is known to retain its potency over a long period if stored at -20°C or below. The storage facili- ties for vaccine in most of the developing countries are inadequate. The cold chain is not strictly adhered to during transport and vaccines are frequently exposed to ambient temperatures.
Which vaccine kept in ice pack?
Ice pack: A water-pack frozen to a temperature between -5°C and -20°C before use. Icepacks are used frozen for the transport of oral polio vaccine (OPV) and used conditioned (see procedure for conditioning further down) for the transport of all other vaccines.11-Jan-2021
The shake test is how you check whether freeze-sensitive vaccines (pentavalent, PCV10, TT or HepB) have been subjected to freezing temperatures, which are likely to have damaged them.
What is the first step in the cold chain?
Cold chain management starts with cold chain storage equipment and facilities. Packaging: when products leave storage facilities, cold packaging is vital to maintaining and monitoring temperature and security.06-Jan-2022
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.
How is vaccine stored?
Vaccine can be stored and transported at -80 °C, -20°C and +2-8°C and shelf life is reduced as vaccine is transferred from one storage temperature to another. Original expiration date should be respected if it comes earlier than the shelf life at -20°C and +2°C to 8 °C.04-Aug-2021
Oral polio vaccine (OPV) is used in other countries. CDC recommends that children get four doses of polio vaccine. They should get one dose at each of the following ages: 2 months old, 4 months old, 6 through 18 months old, and 4 through 6 years old.
Which vaccine should not be stored in freezer?
Preventing Frozen Vaccines The majority of vaccines are not meant to be frozen. Frozen vaccines include the vaccines for chickenpox, shingles and a vaccine combo of Varicella, MMR or MMRV. For vaccines that are only meant to be refrigerated, freezing can be harmful.14-Jun-2019
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 is a cold chain in logistics?
The cold chain process is a logistics management process for perishable products that need refrigerated temperatures to maintain quality and safety from end to end. It involves performing a chain of tasks to prepare, store, and transport products in the cold supply chain.07-Sept-2021
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.
At what temperature are vaccines stored?
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.
