The coronavirus vaccine needs non-stop sterile refrigeration to stay potent and safe. Inspite of the enormous effects in equipping developing countries to maintain the vaccine “cold chain,” it is estimated that nearly 3 billion of the world’s 7.8 billion are surviving in a country where temperature-controlled storage is insufficient for an immunization roll out to bring COVID-19 under control. This results in Poor people around the world,  the hardest hit by the virus pandemic will be last to recover from it, vaccination will be delayed for them.

The coronavirus inoculation program will be the most challenging in those part of the world. To maintain the cold chain in the developing nations, various international organizations are overseeing the installation of tens of thousands of solar-powered vaccine refrigerators. Maintaining the vaccines at stable temperatures from the time they are made until they are given to patients requires mobile refrigeration, reliable electricity, sound roads and, above all, advance planning.
