4 The Cold Chain and Logistics:
What does anything else matter if the vaccine isn’t good? I’ll be presenting a short overview of the cold chain as it works in developing countries. There will be more information and discussion on some of these issues in case studies this week. But for now….. First I’d like to in brief understand about what you will be doing in your assignments? How many of you will be working on SIAs? How many on polio campaigns? Which of you are working on measles campaigns? Routine immunization strengthening? surveillance or data management only? Every one of you has as part of your job, some role which requires understanding cold chain practices in the field! What does it matter if the vaccines are no good? But I’ll need your help because some of you have a lot of experience in maintaining cold chain? How many of you have worked with assuring cold chain in a difficult area already? Excellent—so you are my resources What do we mean by cold chain? Vaccines are sensitive to heat and freezing and must be kept at the correct temperature from the time they are manufactured until they are used. The system used for keeping and distributing vaccines in good condition is called the cold chain. The cold chain consists of a series of storage and transport links, all designed to keep vaccines within an acceptable range until it reaches the user. Logistics and logistics management include vaccines, equipment and supplies that are needed to support the cold chain?

5 The Cold Chain What do we mean by cold chain?
Vaccines are sensitive to heat and freezing and must be kept at the correct temperature from the time they are manufactured until they are used. The system used for keeping and distributing vaccines in good condition is called the cold chain. The cold chain consists of a series of storage and transport links, all designed to keep vaccines within an acceptable range until it reaches the user. Logistics and logistics management include vaccines, equipment and supplies that are needed to support the cold chain? Maintenance of the cold chain requires vaccines and diluents to be: • collected from the manufacturer or an airport as soon as they are available; • transported between 2ºC and 8ºC from the airport and from one store to another; • stored at the correct temperature in primary/central and intermediate vaccine stores and in health facilities; • transported between 2ºC and 8ºC to outreach sites and during mobile sessions; • kept between 2ºC and 8ºC range during immunization sessions; and • kept between 2ºC and 8ºC during return to health facilities from outreach sites. The figure illustrates the cold chain. After vaccines reach the health facility you must: • Keep them between 2ºC and 8ºC in your health facility refrigerator. • Carry them to the immunization session in a vaccine carrier with frozen ice packs or ice. • Keep the vaccines cool using a foam pad in the vaccine carrier while you immunize the children.

6 Which are most sensitive to heat?
In addition to temperature sensitivity , some vaccines are also sensitive to light. BCG and measles are most affected and should be protected from sunlight. Any loss of potency due to heat or light is cumulative, permanent and irreversible.

7 Which do you never want to freeze?
Do Not Freeze Hepatitis B and the tetanus containing vaccines are most sensitive to freezing and should not be frozen. OPV, measles, MR and MMR are added in as they are completely insensitive to freezing. (OPV, Measles, MR, MMR, BCG can be frozen, but not diluents)

8 WHO Recommended Storage Conditions for Vaccines
This slide illustrates the temperatures and time frames for storage at each of the levels of the cold chain for the vaccines. Basically, once delivered to the district level and below, vaccines are kept in the refrigerator compartment. Freezers are used to freeze ice packs only. The correct temperature to store vaccines in a health center is between 2 and 8 degrees C, which in the tropics can only be found in the refrigerator, but there is a margin of safety. If vaccines are kept no lower than 0 degrees or higher than 12 degrees for longer than a week, they may be used.

Opened minimal times per day Generator or kerosene = good ventilation Voltage stabilizers to avoid damage to compressors caused by changes in electricity. Rules for refrigerators. More information can be found in the STOP binder, cold chain section, in Immunization Essentials, chapt. 6 and in Immunization in Practice on your resource CD

13 Storage of Vaccines in Refrigerators
The following two slides illustrate how vaccines should be stored in refrigerators in accordance with their heat and cold sensitivity and air flow within the refrigerator. Vaccines are not to be stored in the bottom shelf as they would be too exposed to cold, and the door should be opened as little as possible to minimize the loss of cold. It takes 24 hours to freeze ice packs. Vaccine that come back from a vaccination session, opened or unopened, should be kept in a special section in the middle marked “use first”.

14 Loading top loading refrigerators
This slide illustrates placement of vaccines and icepacks in top loading refrigerators, with considerations of expiry date and heat sensitivity affecting the positioning of various vaccines in the refrigerator.

15 Good or Not Good? In this refrigerator, they have organized vaccines per local policy as well, but they have added in other medicines. Per WHO policy, if this can be avoided through use of a second refrigerator, it should be. In practice, few health centers will be able to have a second fridge. Staff should be careful to minimize opening the fridge and be especially careful in monitoring that temps do not exceed 8 degrees due to excessive opening to get medicines.

16 Good or Not Good? This is not uncommon, especially in countries that are engaged in campaigns. Fridges will be filled at or beyond capacity during the weeks before a campaign.

17 What do you do? These are vials of OPV thrown in the freezer compartment and frozen there. They will be difficult to extract for use. This fridge should also be defrosted for more efficient operations.

18 Is it working? This slide is of the condition one often finds equipment in. The voltage regulator and outside box of all this equipment was covered in rust. But with proper adjustment, temperatures could be kept within the safe range. (Muzzafarpur District, India)

19 Cold Boxes Insulated for short–term use: 2-7 days
Used in campaigns or when refrigerator out of order Consideration for use and storage capacity, outside temperture, available transport . A cold box is an insulated container that can be lined with ice-packs to keep vaccines and diluents cold during transportation and/or short period storage (from two to seven days). Cold boxes are used to collect and transport monthly vaccine supplies from district stores to the health facility. They are also used to store vaccines when the refrigerator is out of order or being defrosted and for outreach and mobile sessions in addition to vaccine carriers. Different models of cold boxes have different vaccine storage capacities. Health facilities usually need one or more cold boxes that can hold: • a one-month supply of vaccines and diluents; and • a one–to–two week reserve stock of vaccines and diluents. In addition to their vaccine storage capacity, cold boxes are selected according to their cold life. Different models have a cold life of two to seven days depending on the temperature outside. The most suitable cold boxes for a particular health facility are determined by: • the vaccine storage capacity needed; • the cold life needed, that is, the longest time that vaccine will be stored in the box; • the weight and the volume of the box, which depends on how you will transport it – by motor vehicle, bicycle, or hand; and • ice-packs compatible with size of the cold box.

20 Vaccine Carriers and Ice Packs
Like cold boxes, vaccine carriers are insulated containers that, when lined with frozen ice-packs, keep vaccines and diluents cold during transportation and/or temporary storage. They are smaller than cold boxes and are easier to carry if walking. But they do not stay cold as long as a cold box – maximum for 48 hours with the lid closed. Vaccine carriers are used to transport vaccines and diluents to outreach sites and for temporary storage during health facility immunization sessions. In small health facilities they are used to bring monthly vaccine supplies from the district store. Vaccine carriers are also used to store vaccines when the refrigerator is out of order or is being defrosted. Different models of vaccine carriers have different storage capacities. A foam pad is a piece of soft foam that fits on top of the ice-packs in a vaccine carrier. There are some incisions on it to allow vaccines to be inserted in the foam. During immunization sessions, the foam pad serves as a temporary lid to keep unopened vaccines inside the carrier cool while providing a surface to hold, protect and keep cool opened vaccine vials. Previously, ice packs were used to keep vaccines cool during immunization sessions outside of vaccine carriers. It is now recommended to use the supplied foam pads for this purpose. The type of vaccine carrier a particular health facility needs depends on: • the type of vaccines and diluents to be transported; • the number of vaccines and diluent vials, and ice-packs to be carried; • the cold life required; • ice-packs compatible with the size of vaccine carrier; • the means of transport to be used. Ice packs should be placed around the outside. Cold sensitive vaccines should not be placed in the bottom, as cold air accumulates there. Removing the lid is not as damaging as opening the door of a refrigerator, because of this accumulation of cold air at the bottom. It takes 24 hours to freeze ice packs. Directions for packing vaccine carriers. 1 At the beginning of the day of the session, take all the frozen ice-packs you need from the freezer and close the door. 2 Condition frozen ice-packs properly, by allowing ice-packs to sit at room temperature until ice begins to melt and water starts to form. You should check to see if an ice-pack has been conditioned by shaking it and listening for water. This will prevent freeze-sensitive vaccines from freezing. 3 Put conditioned ice-packs against each of the four sides of the cold box or vaccine carrier and on the bottom of the cold box if required. 4 Put the vaccines and diluents in the middle of the cold box or carrier. 5 Include a freeze indicator in the packing with the vaccines, 6 In vaccine carriers, place a foam pad on top of the conditioned ice-packs. In cold boxes, place conditioned ice-packs on top of the vaccines. 7 Close the cold box or carrier lid tightly.

23 Tools for monitoring temperature
Temperature monitoring cards Temperature monitoring charts Shake test Vaccine Vial Monitors (VVM)

24 Temperature monitoring chart for facilities
Using the kinds of tools illustrated in the previous slides, a chart such as this one can be generated by facilities to record the temperature of a refrigerator 2x/day. The monitoring chart should also show maintenance that has been performed, repairs and other.

25 Shake Test (for freeze sensitive vaccines)
The shake test is used to see if a vaccine vial is frozen, which is important for Hep B and tetanus containing vaccines. To perform the shake test, take a vaccine vial of the same type, manufacturer and batch number as the vaccine vial you want to test. Freeze the vial for at least 10 hours at -10°C until the contents are solid, and then let it thaw. This vial is the “control” sample and should be labeled as “frozen” to avoid its use for vaccination. Then take a vaccine vial from the batch that you suspect has been frozen. This is the “test” sample. Vigorously shake the control and test samples for 10 seconds, place both vials on a flat surface to rest, and continuously observe them over the following 20 minutes. View both vials against the light to compare the rate of sedimentation. If the test sample shows a much slower sedimentation rate than the control sample, the test sample has probably not been frozen and may be used. However, if the sedimentation rate is similar and the test sample contains flakes, the test sample has probably been damaged by freezing and should be withdrawn from use. The health worker must notify the supervisor immediately to ensure that any other damaged vials are also identified and withdrawn from use.

26 Vaccine Vial Monitor (VVM)
VVMs are used in certain areas of the world, including Asia and Africa. They change color at temperatures specific to the vaccine. For example, a VVM will change color for OPV, the most heat sensitive of vaccines, if a vial is kept at 37 degrees C for 2 days. However, for TT, will change if kept for 30 days at 37 degrees.

27 VVMs on Vaccines 2 vaccine vials with VVMs indicating that they are acceptable for use are shown.

28 Cold Chain in Campaign Setting

29 Cold Chain in Campaign Setting - Polio
Ice Pack Freezing/Assuring Power Source Sunlight is harmful for OPV vaccine Heavy reliance on VVM Usually use 4 ice packs but in some countries, fewer ice packs OK Ice is acceptable if no other choice Try to protect vials from wet Can keep vials out of vaccine carrier as needed until VVM turns—especially when using vaccine carriers for more than 1 day and need to preserve the temperature. Check VVM each time before putting drops in child’s mouth!

30 Cold Chain in Campaign Setting - Measles
Sunlight is harmful for measles containing vaccine Diluent should be cooled before mixing with vaccine After reconstitution Keep the vial out of the light Keep the vial as cool as possible without freezing it Use foam pad to keep open vial whenever available Vaccine should not be pre-drawn Reconstituted vaccine discarded by 6 hours after adding diluent Sunlight is harmful for measles containing vaccine Measles vaccine can’t be frozen Measles vaccine is not stable if it reaches room temperature In the absence of VVM, countries should adhere to WHO policy that vaccine must be used in 6 hour session
