Omicron Update: Antibodies against Omicron detected. 1 News Track English


Coronavirus New Variant Omicron Update: An international team of scientists has detected antibodies that can neutralize or eliminate Omicron and other variants. These antibodies target parts of the virus’s spike protein that remain unchanged even when the virus is mutated.

This important discovery means that by identifying the targets of these antibodies, vaccines and antibody treatments can be designed that are effective against not only Omicron but also future variants. According to researcher David Weisler of Howard Hughes Medical Institute, the virus can be killed by focusing on antibodies that target specific parts of the spike protein. David Weisler has led this research project. The findings of this research have been published in the journal Nature.

37 mutations in the spike protein of the Omicron variant

The spike protein of the Omicron variant has 37 mutations. It is through the spike protein that the virus enters the cells and sticks to it. It is believed that due to these mutations, this variant has become so infectious. Researchers tried to find out what happened in Omicron that it tricked the body’s immune system’s antibody response.

Weisler and his colleagues speculate that a person with a weakened immune system may have had multiple mutations in the virus over a long period of time. Or else the virus must have passed from humans to some other organism and then again infecting humans.

Vaccines’ effect seen on Omicron

Researchers have also looked at the effect of vaccines on Omicron. The research found that the antibodies of people who had been infected with a previous variant and the antibodies of those who got the vaccine, both of them are less able to block the infection of Omicron. Researchers have investigated antibodies produced by vaccines from Pfizer, Moderna, Sinopharm, Sputnik, Johnson & Johnson and Astra Zeneca.
