C.1.2 Variant: A New Coronavirus Strain Detected across Some Countries

Abstract

Even as the world is facing the repercussions of the deadly Delta variant of COVID-19, the main cause behind the second wave outbreak in India, two other strains of the virus has become a cause of concern globally. C.1.2 COVID-19 variant, first detected in South Africa in May, and Mu also known by its scientific name as B.1.621, first identified in Colombia in January, have been said to be a major cause of concern for the scientists. The World Health Organisation said that it is closely monitoring the new 'variant of interest' Mu or B.1.621 warning that it could be more vaccine-resistant. Mu has been behind the outbreaks in South America and Europe. The new variant exhibits similar spike proteins associated with higher rates of transmissibility, much like the delta variant of the coronavirus, and could potentially have characteristics that would allow C.1.2 to evade vaccine-induced immune responses, but researchers note further observation is needed.
