evidence: Mild neurological effects of the COVID-19 vaccine include weakness, numbness, headache, dizziness, imbalance, fatigue, muscle spasms, joint pain, and restless leg syndrome are more common, while tremors, tinnitus, and herpes zoster are less common. On the other hand, severe neurological complications included Bell's palsy, Guillain–Barre syndrome (GBS), stroke, seizures, anaphylaxis, and demyelinating syndromes such as transverse myelitis and acute encephalomyelitis [10]. Among these, the most dangerous neurological complication caused by COVID-19 vaccines, especially adenovirus-based, is cerebral venous sinus thrombosis in women of childbearing age [8].
