ABSTRACT

Since 1960 our medical science is contributing many things in our advanced healthcare system. Vector is nothing it is a vehicle used to transfer the genetic material into target Cell. In this article we are discussing about vectors, different type of vectors and their application in molecular biology at the Pandemic situation of Covid-19. Viruses have evolved elegant strategies to reach and enter specific target cells where they seize the cellular machinery to express viral genes and assemble progeny particles. In the same way, viral vectors represent the most effective means of gene transfer to modify specific cell type or tissue, and can be manipulated to express therapeutic genes. Viral vectors are usually derived from parental wild type viruses whose viral genes (essential for replication and virulence) have been replaced with the heterologous genes intended for cell manipulation. They can be used as in-vitro tools for biomolecular and gene functional studies, but also to accomplish more demanding tasks such as treat genetic disorders, fight cancer, drive tissue regeneration and monitor cell function. Nowadays victors are played common role in advanced therapies like gene therapies, cell therapies, Viral victor purification and also in vaccine production. Viral victors are now currently involving all across the world to development of effective Covid-19 Vaccine in the pandemic situation of Coronavirus.
