Biologist Baranova: there is a danger that the omicron strain will spread among vaccinated
Professor at the School of Systems Biology, George Mason University, Virginia, Virginia Doctor of Biological Sciences Ancha Baranova worried about the contactless transmission of a new omicron strain of coronavirus. According to her, this may indicate a high ability to spread this variation of infection, reports TASS.
The biologist cited the example of a case in Hong Kong, when people contracted COVID-19 without contacting personally, but one walked along the corridor , where the other had previously visited, in a loosely fitting mask or without it.
Baranova added that the omicron strain can spread along with the delta and begin to infect the vaccinated. “That is, a higher level of antibodies will be required for protection. It is still impossible to guess what these units are, “she said.
The specialist explained that the new variety did not arise from the delta strain. According to her, as a result of a long evolution in the organism of one host, an accumulation of mutations has appeared, four of them evade antibodies, and one has an increased infectivity.
Baranova wondered if the delta would allow a new variety. If this does not happen, then the omicron may “stall”, and then the question of antibodies will no longer be raised.
Earlier, the biologist said that the Russian Sputnik V vaccine could probably form a slightly stronger immunity to the new omicron strain compared with other drugs. The specialist also expressed the opinion that the current remedies for coronavirus are likely to be less effective against the new strain.
A new strain of coronavirus under the code B.1.1.529 was detected in South Africa on November 11. The first confirmed cases of infection date from November 24. The strain was named with the Greek letter “omicron” and has already managed to recognize its danger at the level of the World Health Organization.
