A group of British researchers found that the omicron variant may be less effective at attacking lungs than the other COVID-19 variants.
The British BA Media reported that the Cambridge Institute of Therapeutic Immunology and Infectious Diseases study found that mutations in the Spike protein, which make it able to avoid antibodies, may also limit how it multiplies in the lungs and not cause severe symptoms.
“These observations show that Omicron had properties of immune evasion at the expense of properties related to reproduction and pathogenicity,” the study said.
Another study issued by a group of researchers in Hong Kong showed that the Omicron variant multiplies faster in the airways, but more slowly in the lungs, which may explain the rapid spread of this new variant among people than previous variants, and not cause severe symptoms.
Recently, the Omicron variant has been detected in 89 countries and has a “substantial growth advantage” over the Delta variant, said the World Health Organization, adding, “given current available data, it is likely that Omicron will outpace Delta where community transmission occurs.”
Additionally, two shots of the anti-COVID-19 vaccine are not enough, as their antibodies decrease against the Omicron variant, according to a British scientists’ study results.
This study results showed that boosters’ shots significantly restore protection by more than 70%.
