A couple days later, WHO named this Omicron as well declared it be a Variant Concern (VoC). This evolved during crucial phase current pandemic where vaccination-induced immunity development kept topmost priority combat scenario. Areas Covered: Approximately 50 genomic mutations have rendered more transmissible with larger replicating potentiality, acquiring an immune escape property additional features vaccine-based innate monoclonal antibody neutralizing capability. Information its disease transmissibility severity caused by new is still limited. Heterogenous data available regarding vaccine capability impact clinical outcome treating antibodies. All leading manufacturers are putting their best efforts introduce versions Covid vaccines at earliest point possible counteract strain. Commentary: In spite this, all international health regulatory bodies believe that Appropriate Behaviors (CAB) remain most important step reducing mortality, morbidity, further spread variant.
