Today the vaccine cold chain is broken. Critical vaccines used for immunization or treating chronic illness lie in temperate climates due to lack of power instead of being preserved from 2 Celcius to 8 Celcius. The objective is to replace the current thermocol boxes with gel packs and create a new market for storage while making the device portable for transport - all of this without a battery.


The solar vaccine cooler will be able to provide 24/7 cooling at 2 Celcius to 8 Celcius without the need of a battery. The cooler will address the last mile in a broken cold chain by creating a new market for storage as well as replacement market for existing archaic thermocol boxes with gel packs.
