ADVANCES IN PRODUCTION OF TRADITIONAL VACCINES-A REVIEW
Authors: Borkar T* and Goenka V

ABSTRACT
The most successful and effective preventive measure against infection from a particular disease is to get vaccinated. Traditional vaccines use a dead or a weakened pathogenic microbe or a toxin from a pathogen. Introduction of the attenuated or dead pathogen into a healthy individual generates an immune response. A memory of the antigenic specificity is produced in the individual thus immunizing the individual from that particular disease for a long period of time. Some vaccines do require booster doses to retain the memory of antigenic specificity. Various techniques have been developed and are still under development to produce effective vaccines for several diseases. A key development in traditional vaccines is the reduction of booster doses required as well as reduced side effects. Each technique used to produce vaccines has to ensure provision of long-term immunity to the individual, no side effects on the individual due to the vaccine, no relapse or reversion of pathogenicity, and induction of an immune response at a low dosage. This article aims to highlight the progress and failures in the development of different types of traditional vaccines, along with the procedures and techniques used in the traditional vaccine production.
