William Hanage, an epidemiologist at Harvard’s T.H. Chan School of Public Health, spoke mainly about the fact that the delta variable and its subvariables are now ubiquitous around the world. AY is currently shown in our region. Variant 4.2 according to Hanage, is “no more giant contagion” than the “smooth” delta variant. According to the World Health Organization, the variant also referred to as ‘delta plus’ is 10-15% more contagious.
Ravi Gupta, a microbiologist at the University of Cambridge, said he was “80% sure” that in the next two years there would be a mutation that would be more contagious and cause more severe symptoms than the delta variant.
He also spoke of the ‘conceivable possibility’ that delta and another variant would perform viral recombination, which could lead to the formation of a ‘super mutant’. He added that this phenomenon, fortunately, “is not very common.”
According to Gupta, such a mutant could develop in parts of the world where delta dominance has not yet been confirmed. He added that vaccines can only reduce the chances of developing a supermutant.
Scientists also talked about the possibility that due to the many mutations, sooner or later there will be a variant that is no longer protected by current vaccines.
