Two Russian scientists in the field of immunology and biology discussed the phenomenon of multiple Corona strains and explained its origin and how to identify them, in light of the latest strain discovered in Britain.
Immunologist Vladimir Bulibuk noted that “Corona is an RNA-based virus and it is mutating heavily. There are already several thousand of these point mutations, and not all of them lead to the kind of changes in characteristics that are worth talking about. at the beginning of the epidemic. With almost all the changes, we are really tired, and that’s why the reaction was so slow. “
The Russian specialist in human immunology noted that “it was necessary to ensure the spread of this new mutation, and if this spread remained isolated, or only led to a local outbreak, this would not attract attention. But the mutated virus managed to spread, and this is a different story”. “.

Regarding the unusual symptoms that can be detected with this mutated virus, Pollock said: “There is no need to speak of any new symptoms, especially for those infected with this particular strain, which have not been distinguished mainly in Britain by the symptoms. Health institutions specialized in virology in the countries are constantly monitoring “. And trace the genomes of the virus in patients (study and decoding) And when they began to discover that something unusual is often detected in patients, this matter became a green light for them to start talking about a new strain.
As for the professor of biological sciences at Moscow University, Nikolai Nikitin, he believes that “people who enter the clinic with a serious infection take a swab from them, and the virus is isolated and its genome is determined, that is, reading the RNA sequence in which all the proteins of this coronavirus are encoded. ” Compare these sequences with those in the database. Thus, virus mutations are identified. “
Regarding the time needed to understand the characteristics of the new strain, the academic pointed out that this “usually takes at least a few weeks, since a series of experiments related to infection by this virus must be carried out. Scientists must first read the complete genome sequence and determine how it differs from circulating strains. ” In fact, suppose the British strain is already known, there are about 18 mutations. Now scientists have to work hard to study this modification of the virus in animals. You need to understand how fast (the new strain) reproduces and how efficiently it sticks to a surface. The cell. It is necessary to note how this affects people, how fast it is transmitted, how many people will be infected with it, what are the complications, mortality rate, etc. For these reasons we will not receive any important new information before the new year arrives.
And whether the vaccines against the new mutations work or not, replied the Moscow University professor, noting that “the final answer can be obtained as part of the research that will be carried out with the new strain. But most vaccines they target the field of binding receptors for the spike protein of the SARS-Cove virus. ” 2) If the mutation is in this area, then the virus will not be contagious and will not be able to infect anyone, as it infects, the performance of vaccines should not be affected, but this also requires further research.
