Biologist Baranova: the delta strain restrains the mutation of the coronavirus, its disappearance is dangerous 
be dangerous for Russia, since this option inhibits other strains due to its infectivity. Ancha Baranova, a biologist and professor at the School of Systems Biology at George Mason University (Virginia, USA), said this in an interview with Lente.ru.
“Delta is transmitted faster than other strains, so they have little chance of multiplying … There are strains that are more harmful, among them those that evade antibodies, which means that the vaccine takes them worse. Therefore, if the delta dies by itself, and other strains are happy and come, it will probably get much worse, “she explained.
Earlier it was reported that the World Health Organization (WHO) doubts that that the delta strain could self-destruct. According to the representative of the organization, the disappearance of this type of virus is unlikely, since people in countries outside of Japan are still infected with it.
As Baranova suggested, a sharp decrease in the number of cases of coronavirus infection threatens the emergence of new strains resistant to antibodies … In her opinion, delta is indeed the final variant of COVID-19, since the emergence of new variants would be accompanied by a weakening of its infectivity.
