Editorial: The 2022 World Health Organization (WHO) Priority Recommendations and Response to the Omicron Variant (B.1.1.529) of SARS-CoV-2

The omicron variant of SARS-CoV-2, B.1.1.529, was included in the World Health Organization (WHO) list of variants of concerns (VOC) on 26 November 2021. Within only three months, omicron has spread rapidly to become the dominant variant in many countries. Studies have begun to evaluate the virulence, transmissibility, and degree of immune protection from current SARS-CoV-2 vaccines or previous of infection with the omicron variant. On 21 January 2022, the WHO published its seventh technical update and recommendations for priority actions in response to the omicron SARS-CoV-2 variant and cautioned that the overall risk from omicron remains high. At the start of this third year of the global COVID-19 pandemic, this editorial aims to summarize the evidence that supports the current priority recommendations and response from the WHO regarding the omicron variant of SARS-CoV-2, B.1.1.529. © Med Sci Monit, 2022.
