Study: Omicron mutant is less effective in attacking the lungs compared to other mutant

British researchers have concluded that the Omicron mutant may be less effective at attacking the lungs than other mutant coronaviruses.

And the British BA Media reported that a study by the Cambridge Institute of Therapeutic Immunology and Infectious Diseases found that mutations in the Spike protein, which make it able to avoid antibodies, may also limit how it multiplies in the lungs and causes severe symptoms.

The study said, "These observations show that Omicron had characteristics of immune evasion at the expense of characteristics related to reproduction and pathogenicity."

The study's lead author, Ravi Guptar, professor of clinical microbiology, said there were still challenges despite the positive results.

He tweeted: "What does all this mean? Infection in lung cells can be related to the severity of the disease in the lung. It is often possible to detect fused cells in respiratory tissues that are tested after acute illness. The delta mutant could do both, unlike the mutant." Omicron. More studies need to be done."

He added, "The conclusion is that this study indicates that it appears that the omicron mutant has become more capable of evading immunity, but the characteristics associated with disease progression may be weakened to a certain degree. However, the observed spread of the omicron mutant represents a major health challenge."

The study comes after the Scientific Advisory Group for Emergencies said it was "almost certain that hundreds of thousands of omicron cases are now being recorded daily" in England, prompting media to speculate that stricter restrictions could be imposed after Christmas.
