Coronavirus disease 19 (covid-19) is an infectious disease caused by the novel SARS-CoV-2 (Severe Acute Respiratory Syndrome Corona virus-2) has emerged as a worldwide threat in December-2019 and then spread rapidly. Scientists and Clinicians are attempting to find antivirals specific to the virus, vaccine development for a novel virus is a challenging effort for them which may take several years to discover. Design and repurpose of existing drugs have been studied by researchers for the approval of other conditions which are effective against covid-19. Repurposed drugs may not be highly potent, as they are not developed specifically to this particular virus. Finally, two vaccines have been granted for emergency use approval in India by the government. The main purpose of this study on covid-19 vaccine development, repurposed drugs and approved drugs- its side effects, advancements and challenges during vaccine development. By this we can understand the vaccine development process and its current authorized approved drugs.
