STORAGE CONDITIONS OF DIFFERENT TYPES OF VACCINES

Vaccines are the biological preparations which are considered as the most economical and effective preventive step against the most contagious, non-contagious deadly infectious diseases. Vaccine contains a particle/agent that provides protection against infection by activating the immune system or on subsequent exposure to a pathogen. Due to the pandemics prone to the world from ancient times different types of vaccines are designed based on requirement and administered in to human body to teach immune system how to fight off with foreign particles or pathogens. This review includes the detailed information of the vaccines, importance of vaccines, stability and storage conditions of vaccines. Vaccines has its own stability issues which are caused by light, heat, radiation, changes in environment, reactions with container or with other components in the mixture which must be considered during development, storage, transport. A cold chain is a temperature-controlled supply chain used to maintain the vaccine stability problems during its storage. Any fluctuation in temperatures during manufacturing, transporting, it results in decrease in vaccine potency and increase in risk of vaccine preventable diseases.
