A review on potential COVID-19 vaccines

Abstract

A novel coronavirus unexpectedly erupted in Wuhan, China, in December 2019, triggering human to-human transmission. As a result, there was a massive outbreak of respiratory disease in that region and this coronavirus became a lethal pathogen within a brief amount of time, causing an epidemic and later becoming a global pandemic. The disease caused by the novel coronavirus is named as Corona Virus Disease 2019 (COVID-19). There is no realistic therapy for permanently curing COVID-19 at this stage. However, various medicines demonstrate improved outcomes against the virus, but it is also suggested that this pandemic could be avoided by a potential vaccine. There are currently several ongoing initiatives for the production of a vaccine, with some of the candidates displaying encouraging results. ChAdOx1 nCoV-19 is the most promising candidate among them. Therefore, the primary goal of this research is to analyze the potential solutions and effects of the existing vaccine candidates and to highlight that the ultimate solution will be vaccine.
