“The delta coronavirus variant in Japan was transmitted at a high rate and supplanted other variants.
But as mutations accumulated in him, we believe that he became defective and unable to produce copies of his own ... We believe that ... he directed himself straight along the path to natural self-destruction, "RIA Novosti quotes the statement of the head research team, Professor Itsuro Inoue.
According to scientists, a significant part of the changes in the "delta" variant happened at the site of the protein responsible for the ability of the coronavirus to "correct" deficiencies.
“A virus with a damaged nsp14 protein significantly loses its ability to reproduce, so this may be one of the factors behind the sharp drop in the number of new infections,” said Takeshi Urano, a Japanese scientist and professor at the Faculty of Medicine at Shimane University.
He also warned that the self-destruction of the delta strain of COVID-19 in Japan could lead to other types of new coronavirus infection penetrating there.
Earlier, Russia began to develop two vaccines for the prevention of coronavirus infection based on the delta strain COVID-19.
