Omicron infected have significant immune response, can neutralise Omicron, Delta: ICMR
The study analysed the IgG and neutralising antibodies (NAbs) against B.1, Alpha, Beta, Delta, and Omicron variants with the sera of individuals infected with the Omicron variant (B.1.1529 and BA.1). It suggests that the immune response induced by the Omicron could effectively neutralise the Delta variant, making re-infection with Delta variant less likely and displacing this varaint as the dominant strain.
