Using the vaccine stacks

• Each device is equipped with multiple interlocking vaccine stacks.
• These vaccine stacks are designed to be stacked together within the device. There are large and small cups, and the cups can be stacked in different configurations, forming a total of 6 stacks- 4 square stacks and 2 triangular stacks.
• Each stack has a black nylon handle. The handles make it easy to lift the vaccine stacks.

Removing the stacks

1. Unlatch and remove the cap from the device.
2. Remove the stack in the middle first.
3. Remove other stacks one by one.
4. Replace and latch the cap.

Loading the stacks

1. Unlatch and remove the cap.
2. Place two triangular vaccine stacks and one square vaccine stack into the device. The square stack is in the middle of the two triangular stacks. Push the vaccine stacks against the inside wall of the device.
3. Place one of the other three square vaccine stacks into the center of the device. Push the vaccine stack against one of the inside walls of the device.
4. Repeat step 3 with another of the square vaccine stacks, positioning it against the inside wall of the device opposite the vaccine stack. This will leave a space in the center of the device for the third vaccine stack
5. Place the last square stack into the center of the device.
6. Replace and latch the cap.

Note: All the vaccine stacks may need to be adjusted for all vaccine stacks to fit into the device.

Loading up with vaccines

• Note: Foam protective pads and plastic dividers can be used to organize them. Vaccines can be placed in the cups vertically or horizontally. Do not overfill the vaccine cups.
• Leave gaps between vials and cups to enable cold air circulation.
• Important: work to complete this entire process within three minutes– or less, ideally. Exceeding three minutes will risk unwanted warming of vaccines and a decrease of safe-storage hold times.

1. Unlatch and remove the cap.
2. Remove the three vaccine stacks from the device and quickly replace the cap.
3. Set the vaccine stacks on a flat surface to fill them.
4. Working quickly, separate the cups from each other by twisting them apart and lifting them off the stacks.
5. Quickly and carefully place the vaccine into the cups.
6. Reassemble the cups by twisting them together into a set of stacks.

Set up vaccines, daily or weekly

• There is a designated “day use” cup, located in the top-most accessible position in the device, designed to hold all of the vaccine vials needed for the day. The “day use” cup is designed to be easily accessible when the device is opened.
• To administer the vaccines efficiently, you can arrange the vaccines in the designated “day-use” cup so that they will be easily accessible throughout the day.
• This process can be done daily or weekly – depending upon the volume of vaccine usage. If possible, to minimize the warming of the vaccines, arrange the cup stacks in the morning, when the surrounding ambient temperature is the lowest.
• The vaccine stacks should only be removed during this routine set-up time, not during the day when you should simply be accessing individual vaccine vials.

1. Unlatch and remove the cap from the device.
2. Remove only the stacks needed to properly refill the day-use container.
3. Immediately recap the device to avoid unnecessary temperature transfer.
4. Moving quickly (on a flat work surface) twist apart the cup stacks and lids.
5. Place the current day’s supply of vaccines into the day-use container.
6. Twist to reconnect the containers and lids into stacks, placing the day-use container at the top of one of the stacks.
7. Replace the vaccine stacks in the device, one at a time.
   • The stack with the day-use cup must go into place last to be located in line with the device access channel.
8. Replace the cap on the device and latch the cap in place.

Access vaccines for immunization session

1. Unlatch and remove the cap.
2. Reach into the day-use cup and take out vaccines.
   • Note: Do not remove stacks during the day unless necessary to refill the day-use container.
3. Return unused vaccine to “day-use” cup.
4. Immediately replace the cap. Minimize lid open time.
