Israeli researchers have identified two antibodies from the immune systems of COVID-19 patients who have recovered that have a 95% chance of neutralizing all known strains of SARS-CoV-2, including Omicron.The investigation, which was just published in the journal Communications Biology, is an extension of initial work done in October 2020 at the height of the COVID-19 crisis.

The researchers found nine antibodies after sequencing all of the B immune system cells from the blood of persons who had recovered from the initial COVID-19 strain in Israel at the time. According to the research, the new coronavirus variants, Delta and Omicron, can be neutralized by some of these antibodies.

The SARS-CoV-2 virus uses the spike protein to invade and enter cells. Researchers demonstrated that the Delta and Omicron variants could be effectively neutralized by two more antibodies, TAU-1109 and TAU-2310, which bind the viral spike protein in a different location than the sites where most antibodies have previously been focused.

According to experts, the first antibody, TAU-1109, is 92% successful at neutralizing the Omicron strain and 90% effective at neutralizing the Delta strain. The second antibody, TAU-2310, is 84% effective at neutralizing the Omicron variation and 97% effective at neutralizing the Delta variant. Thus these findings may be a helpful alternative for vaccines, especially for high-risk groups and immunocompromised people.
