Geneticist evaluated the effectiveness of antibodies after the delta strain against omicron

Geneticist Isaev: antibodies after the delta strain of coronavirus may not protect against the omicron

Antibodies produced after infection with the delta strain may do not protect against omicron contamination and vice versa. Andrey Isaev, founder and general director of the Scientific Center for Molecular Genetic Research DNKOM, told TASS about this.

According to him, a large number of mutations means that the virion of the virus of this variant is structurally different from the virions of other strains of COVID-19. So, their proteins differ, the geneticist emphasized. He noted that therefore, antibodies produced by people who have been ill with other strains or were vaccinated may not bind omicron. Thus, cross-immunity between omicron and other strains of coronavirus does not arise.

In addition, the specialist said that COVID-19 can split into two populations: covid-D and covid-O.

< p> Earlier it was reported that the new omicron-strain COVID-19 during the next mutation could take part of the genetic material from another respiratory virus, possibly causing the common cold. This is the conclusion reached by a group of specialists from Nference. The researchers said that this omicron-strain genetic sequence was not found in any of the earlier variants of the coronavirus called SARS-CoV-2, but is common in the human genome and in many other viruses, including those that cause the common cold.
