Bharat Biotech said the study conducted using a live virus neutralisation assay showed the booster dose generated robust neutralising antibody responses against both Omicron (B.1.529) and Delta (B.1.617.2). “100% of test serum samples showed neutralisation of the Delta variant and more than 90% of serum samples showed neutralisation of the Omicron variant,” Bharat Biotech said.
