<p>Keith Bartlett of True Energy in the United Kingdom will work with stakeholders in the immunization community to create a prototype vaccine storage device that uses the properties of water density to maintain vaccines at 4°C during the "last mile" of the cold chain. A water container that maintains the liquid at a steady temperature of 4°C will be in contact with the vaccine storage area, preventing temperature fluctuations that can damage or destroy vaccines.</p>
