Arktek Guinea

Arktek cold storage vaccine storage device in use during the Ebola vaccine trials in Guinea, June 29, 2015. The Global Good Fund--a joint project between the Bill and Melinda Gates Foundation and Intellectual Ventures--donated dozens of Arkteks to the vaccine trials in Guinea and Sierra Leone. To reliably achieve the required temperatures for Ebola vaccines, the Global Good Fund modified its Arktek PSD device-a storage device that keeps vaccines cold for over a month with no power required. The Ebola vaccine needed to be stored at much lower temperatures --76 to 112 degrees Fahrenheit/-60 to-80 degrees Celsius- than licensed vaccines.
