A Focused Review on Emerging SARS-Cov-2 Variants

Over the past 33 months, 10 SARS-CoV-2 mutant variants have evolved. Among them, very few were infectious, while the rest were not that rampantly infectious. As COVID-19 has been the century’s most destructive pandemic, and as the variants of concern and significance are heralding nature, there is an inherent need to bring collaborative convergence among scientists to combat future pandemics such as COVID-19. A question remains whether these emerging variants could allow us to define the advent of pathogenesis and whether or not we are prepared. In this review, we give a gist of variants that could be associated with the recombination events concerned with SAR-CoV-2 that have an impact on the immune response in the human body.
