Vaccination Studies Against COVID-19 Agent: Current Status

The emergence of the new pathogenic viral strains is a constant threat to global health. The latest new coronavirus strain coronavirus-2019 (COVID-19) is the best-known example of this. COVID-19, caused by the severe acute respiratory syndrome-CoV-2 virus has quickly spread around the globe. The applications of drug and vaccine practices, and the identification of potential candidates are of high importance against this pandemic. On healthy adults, a proper evaluation of potential vaccines in parallel with vaccination studies on animal models and an enlargement of production capacity will benefit minimum risk and accelerated COVID-19 vaccine studies for human subjects. The purpose of this review is to contribute to the analysis of vaccine development strategies, vaccine development stages, phase studies and the difficulties, production stages and current status of potential vaccine studies developed to prevent COVID-19.
