Immunization is one of the best-known methods for effectively preventing many life-threatening childhood illnesses. Yet，more than a million children die each year from vaccine-preventable diseases. This is due in part to the temperature-sensitive nature of the vaccines themselves, which spoil if they're not properly kept cool from manufacture all the way to point of use. Cold storage for vaccines is a particular challenge in hot，remote settings due to the lack of reliable power sources，parts for repairs, and expertise needed to upport refrigeration equipment.
To help strengthen the vaccine supply chain-the“cold chain”-in underserved regions, AUCMA and Global Good have partnered to provide a Passive Vaccine Storage Device(PVSD)that requires no power source and can keep vaccines cold for a month or more on a single set of frozen ice blocks. vaccines in the device can be retrieved as needed without jeopardizing the remaining vials，and the device can be easily serviced, restocked and redepoloyed into the field. With a reasonable distribution programs, each device contails the vaccine to meet the needs of the community of about 6,000 people.
Ice blocks and vaccines are loaded into the PVSD using the access opening on the top of the device. The ice blocks are stacked against the inner wall, and the vaccine carrier cup-stacks are then loaded into the center. Health workers can easily retrieve and replace the vaccine vial stacks several times per day as the Arktek continues to stay cold and protect the vaccines.

About the Device
The Arktek PVSD combines several technologies to maintain stable cold internal temperatures for vaccine protecton. Its core vacuum-walled flask is integrated with overall design and materials that mitigate unwanted heat exchange. In rigorous testing, the device has been proven to keep vaccines within the 0℃ to 10℃ range for over 35 days-even in hot climate conditions.

For additional verification that the vaccines remain protected，the temperature sensors and on-board electronics and will provide an alert if the interior area goes below the safe temperature range.
- Holds vaccines between 0℃ and 10℃ for over a month using only a single load of ice at hot zone temperature environment of 43℃/25℃.
- Can handle rough roads and harsh environments.
- Provides capacity to serve a community of up to 6,000(at 250cc per fully immunized chiId)
- Automatically alerts if internal temperature goes below allowable limits.
- Designed to work easily with typical replenishment cvcles.
