Vaccine. 2011 Oct 26;29(46):8182-5. doi: 10.1016/j.vaccine.2011.08.103. Epub 2011 Sep 17.

Abstract

Introduction: Approximately 5% of cases of acute disseminated encephalomyelitis are preceded by vaccination within 1 month prior to symptom onset. This occurs rarely following influenza immunization.

Methods: Case presentation and literature review.

Results: A 75-year-old woman developed acute disseminated encephalomyelitis within 3 weeks of receiving the seasonal influenza vaccine. The patient subsequently passed away, despite treatment with methylprednisolone and plasma exchange therapy.

Conclusions: The literature on post-influenza vaccination encephalomyelitis is limited. The majority of published cases had favourable outcomes following treatment with intravenous methylprednisolone. Given the limited number of cases, no incidence estimates have been published.
