Omicron variant underwent fundamental changes, reveals study

India TV News  

The Omicron variant of SARS-CoV-2, which represents a step-change in the Covid-19 pandemic with record numbers of new daily infections being reported around the globe, has undergone fundamental changes that may explain its spread and disease. The results, published as a pre-print study and not yet peer-reviewed, from laboratory tests showed that Omicron is largely unaffected by the antibodies provided by two doses of Covid-19 vaccine, but responses are improved by a third-dose booster. This has been confirmed by analysis of real-world infection data; Omicron escapes immunity from two vaccine doses, but three doses restore good levels of protection. Further, the study also provided evidence that Omicron has switched its route of entry into human cells, from cell surface fusion to cathepsin-dependent fusion within the endosome.
