omicron: Coronavirus: Immunity due to Omicron variant can prevent Delta re-infection, says ICMR-NIV Study – The Economic Times Video

Individuals infected with Omicron have significant immune response which could neutralise not only Omicron, but also other variants of concern, including the most prevalent Delta variant, an Indian Council of Medical Research (ICMR) study showed 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.
