The emergence of newer SARS-CoV-2 variants recently reported in the UK, South Africa, and Brazil is a matter of great concern. The mutations mainly in the spike protein are the culprit behind the sudden rise in the infectivity and transmission of these variants. The scientific efforts provided us with few effective vaccines like Pfizer and Moderna, however the same needs to be re-investigated in the SARS-CoV-2 variants infected patients. This brief review, focuses on the emergence, how the variants originated and are geographically distributed around the world, which will make the researcher aware of the current pandemic situation.
