The influence of Omicron on vaccine efficacy and durability: a neurology perspective

Omicron variants present new challenges when it comes to understanding their impact on vaccines, antiviral strategies, and possible neurological consequences. This article describes the characteristics of the Omicron variant, its epidemiology, the efficacy of vaccines and monoclonal antibodies, and its association with lymphoid depletion. We also explore the neurological implications of Omicron, focusing on its association with encephalopathy and encephalitis. There are unique challenges associated with the Omicron variant, which is characterized by distinct mutations and increased transmissibility. For a better understanding of the effects of this disease and developing strategies to combat its spread, especially concerning neurological complications, ongoing research is necessary.
