With a total spending of about US $500 million every year, India has one of the largest Universal Immunization Program (UIP) in the world. The program entails immunizing children against vaccine preventable diseases. Currently, the following diseases are such as Polio, Measles, Pertussis (whooping cough), Diphtheria, Tetanus, Tuberculosis, Hepatitis B, and Japanese Encephalitis. Cold chain, i.e. the supply chain involving storing and transporting products at the recommended temperature range from the point of manufacture to point of use, is an extremely important component to ensure that each immunized child receives quality vaccines.
