Shane Crotty, an American virologist and professor at the La Jolla Institute of Immunology, called the chance of a new, vaccine-immune variant of the coronavirus unlikely.
The scientist believes that such a development of events does not correspond to the pattern of behavior of the pathogen, TASS quotes him as saying. In addition, Crotty says, even if the virus bypasses the immune system, there are other antibodies in the body that can recognize the virus. As the American specialist explains, the immune system has many different strategies for recognizing pathogens.
Shane Crotty points out that the most serious challenge at the moment is the “delta” strain, which differs in its speed of propagation. As the scientist explained, due to the fact that this variant of COVID-19 is faster, it reproduces more in the body and is more difficult to stop. However, Crotti recalled that existing vaccines successfully cope with this strain.
Earlier, the head of WHO, Tedros Adan Ghebreyesus, said: the wider the spread of the virus, the more its variants will appear, while with the potential to become even more dangerous than “Delta” -variant… He believes that as the number of strains increases, the chance that one of them will be able to dodge vaccines increases. Our publication published an appeal from WHO:
“We expect the Delta option to quickly outperform other options and become the dominant (Covid) option to be released in the coming months. Among the countries where the Delta variant is now the cause of more than 75% of new cases of this disease are India, China, Russia, Indonesia, Australia, Bangladesh, Great Britain, South Africa, Australia, Portugal, Israel. However, we still do not know the exact mechanism by which this option is the most contagious compared to others. “
