Scientists find how Omicron sub variants escape immune system, spread rapidly

Scientists in the US have found the mechanism that the BA.1 and BA.2 Omicron sub-variants use to escape antibodies and spread rapidly, an advance that could lead to new therapeutic targets and help update COVID-19 vaccine formulations.

The researchers found that the two dominant sub lineages of Omicron have unprecedented numbers of spike protein mutations, with BA.1 having 33 and BA.2 having 29 variations.
