Encephalomyelitis generally refers to acute disseminated encephalomyelitis, there is no such thing as how long does rabies vaccination rule out acute disseminated encephalomyelitis, rabies vaccination does not directly induce acute disseminated encephalomyelitis, so there is no need to worry too much. At present, there is no authoritative data to show that rabies vaccination can induce acute disseminated encephalomyelitis. The pathogenesis of acute disseminated encephalomyelitis is not yet clear. It may be due to over-activation of immune function after viral infection, resulting in an autoimmune response, or the release of hidden antigens that are misrecognized by the body, resulting in an immune attack on the body’s own myelin sheath. The disease is prevalent in children and young adults, and patients often present with high fever, headache, dizziness, generalized body aches and pains, and in severe cases, epileptic seizures, lethargy and deep coma. Patients are advised to follow the doctor’s instructions for regular review after rabies vaccination in order to know how their body is recovering. In daily life, the local skin should be kept clean and tidy to avoid secondary infection.
