There is now clear experimental and clinical data supporting very high immune escape potential of Omicron, but initial estimates show the severity of illness being lower than what was seen in previous outbreaks, the Indian SARS-COV-2 Genomics Consortia INSACOG said in its latest bulletin citing global data.

In India, appropriate public health measures and investigations are being conducted for surveillance of Omicron, INSACOG said while noting that globally there appears to be significantly reduced ability of vaccines or prior infection to protect against symptomatic infection by the Omicron variant.
