COVID‐19: Clinical status of vaccine development till date

Abstract

Severe Acute Respiratory Syndrome Coronavirus‐2 (SARS‐CoV‐2) induced COVID‐19 is a complicated disease. Clinicians are continuously facing difficulties to treat infected patients using the principle of repurposing of drugs as no specific drugs are available to treat COVID‐19. To minimize the severity and casualty, global vaccination is the only hope as a potential preventive measure. After a year‐long global research and clinical struggle 165 vaccine candidates are developed and some are in the pipeline till date. Out of them 28 candidate vaccines are approved for their use and rest of them are in the different phases of clinical trials. In this comprehensive report, authors aim to demonstrate, classify, and provide up‐to‐date clinical trial status of all the vaccines discovered till date and specifically focus onto the approved candidates. At last, specifically focused on the vaccination of different type of medically distinct populations.
