What is the equipment used to maintain the cold chain?
The common cold chain equipment used in Health Posts are refrigerators, cold boxes, vaccine carriers, ice-packs and foam pads.
A cold box is an insulated box used for transportation and emergency storage of vaccines and ice packs.
How do you store vaccines in a cold box?
In order to protect freeze-sensitive vaccines, frozen icepacks should be conditioned before they are lined in non-freeze preventative CBs or VCs. Conditioned icepacks or cool water packs between + 2°C to +8°C are used to keep vaccines cool inside the non-freeze preventative vaccine carriers or cold boxes.11-Jan-2021
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. Vaccines must be continuously stored in a limited temperature range – from the time they are manufactured until the moment of vaccination.
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.
BCG storage BCG vaccine can be also affected and damaged by heat and light, so it should be stored between +2°C and +8°C. The vaccine powder may be frozen for long-term storage, but the diluent and the reconstituted vaccine must never be frozen.
How many types of cold chains are there?
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
They are used to keep vaccines cool inside the vaccine carrier or cold box. The number of coolant packs required for a cold box or vaccine carrier varies according to the type of cold box or vaccine carriers. Every cold box or vaccine carrier should have at least two sets of coolant packs.
How long can vaccines stay in a cooler box?
Temperature monitoring at school immunisation clinics Correct equipment for storing and transporting vaccine is dependent on the type of conditions (such as ambient temperature) and period of time they will be transported. Portable coolers are adequate for the transport of vaccines for eight hours or less.
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
How do you maintain cold storage?
Monthly Maintenance of Cold Rooms
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.
Which vaccine is most sensitive to freezing?
Some of the most widely used vaccines are freeze-sensitive, including:
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.
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.
DPT, DT, dT, TT, Hepatitis B and typhoid contains such adjuvant and so can not be frozen. Lyophilized or powder type of vaccines do not freeze as they have no liquids in it and so storage in freezer compartment or lower shelves do not make difference.
Why vaccines should be stored in a refrigerator?
When thawing, the recrystallization process exerts tension and shear stress on the proteins. Storing vaccines at cool temperatures also lessens the need for other preservatives and lessens the risk of bacterial growth within the vaccine.11-Nov-2020
Temperature Ranges. Refrigerators should maintain temperatures between 2°C and 8°C (36°F and 46°F). Freezers should maintain temperatures between -50°C and -15°C (-58°F and +5°F).
Is IPV stored in the freezer?
Inactivated vaccines must be kept between 2° and 8°C (between 36° and 46°F) and not frozen.19-Feb-2021
OPV. Pack with dry ice. Should be delivered within 3 days. *Should be frozen.03-Jan-1991
What is the storage temperature of BCG?
The intact vials of BCG VACCINE should be stored refrigerated at 2–8°C (36–46°F). This agent contains live bacteria and should be protected from direct sunlight.
