вакцины COVID-19 и неврологические расстройства: повествовательный обзор иммунной реакции и неблагоприятных реакций.

COVID-19 vaccines and neurological disorders: A narrative review of immune responses and adverse reactions.

COVID-19 vaccines have been effective in providing strong immunity within a relatively short time frame, significantly reducing both the severity of the disease and associated mortality. However, post-vaccination complications, particularly neurological disorders, have been reported. Among the more frequently documented neurological complications are acute disseminated encephalomyelitis (ADEM), multiple sclerosis (MS), transverse myelitis (TM), optic neuritis (ON), Bell's palsy (BP), and Guillain-Barré syndrome (GBS). The precise role of COVID-19 vaccines in triggering the onset or relapse of these conditions remains uncertain. Immunological processes involving cytokines, chemokines, antibodies, and immune cells are believed to contribute to the pathogenesis of these neurological side effects. This review examines the immune responses triggered by COVID-19 vaccines and their potential role in the development of such complications. Despite reports of neurological side effects, these cases remain rare, and the overall benefits of vaccination in curbing the pandemic and preventing severe illness far exceed the risks. It is vital to sustain the progress of global vaccination efforts while continuously evaluating the risk-benefit ratio, particularly for individuals with underlying conditions. Ongoing research and surveillance are crucial for creating safer vaccines and identifying individuals who may be more susceptible to adverse reactions, ensuring broader protection against COVID-19.
