Current State of Developed COVID-19 Vaccines; Light at the End of the Tunnel

Abstract

COVID-19 pandemic has posed a dire threat to global health. Safe and effective vaccination can play an important role in preventing the transmission of the virus, SARS-CoV-2 (Severe Acute Respiratory Syndrome Coronavirus type 2). The right choice of vaccine type, carrier, or vector as well as the dosage of vaccine can have a direct impact on the resulting effectiveness against the illness, COVID-19. Therefore, there is tremendous pressure on researchers to develop safe and effective vaccines against the virus SARS-CoV-2 and the resultant illness. In addition, this pandemic is an alarm to the world that we have to prepare ourselves for various consequences of SARS-CoV-2 or another unpredictable pandemic in the future. This review described leading vaccines developed against SARS-CoV-2; Comirnaty, mRNA-1273, Sputnik V, Ad26.COV2.S, Vaxzevria, NVX-CoV2373, BBIBP-CorV, CoronaVac, Convidecia, and BBV152.
