ALTERNATIVES FOR REFRIGERATED VACCINES: A CONTEMPORARY PREREQUISITE

Immunological preparations like vaccines are vital for the progress of global population. For vaccines to be effective, it is essential that they are stored and preserved under refrigeration. This calls for infallible cold chain supply in order to maintain the potency of vaccines from manufacturer to user. Enormous investments are required in the development and maintenance of cold chain logistics and related infrastruct ure which in turn elevates the cost of immunization. Such expensive vaccines and other related issues of apprehension disappoint the purpose of preventive healthcare. Hence, several technologies are sprouting out as alternatives for refrigerated vaccines . This review highlights the recent developments, existing R&D status and future scope in vaccine technology.
