Invention and Apprehension in Development of Covid 19 Vaccine-A Comprehensive Review

Abstract

Covid-19 is an infectious disease, caused by the newly discovered coronavirus, SARS-CoV-2 and has spread rapidly throughout the globe. The World Health Organisation (WHO) declared the Covid-19 outbreak pandemic in March 2020. All the countries, including India, have adopted stringent measures to contain the disease through better diagnostic measures, treatment protocols and containment sanitation measures with limited success. Development of effective vaccines are expected to provide a lasting solution by enhancing immunity. The vaccine development procedure has been fast-tracked in order to contain the disease spread on emergency basis following stringent protocols. Apprehensions and concerns regarding the safety, efficacy and immunogenicity of these vaccines based on new and never licensed platforms do exist.
