BACKGROUND: Although postvaccination Guillain-Barré syndrome is commonly reported, there have only been 2 previously reported cases of postvaccination Miller Fisher syndrome, and none in association with the novel influenza A(H1N1) vaccine. OBJECTIVE: To describe a case of Miller Fisher syndrome following receipt of the seasonal influenza and novel influenza A(H1N1) vaccine. DESIGN: Case report and literature review. SETTING: Vancouver General Hospital. PATIENT: A 77-year-old Chinese woman. RESULTS: The patient presented with ophthalmoplegia, ataxia, areflexia, and a sensory neuropathy within 2 weeks of immunization. Findings of parainfectious evaluation were unremarkable. Treatment with 2 courses of intravenous immunoglobulin led to clinical improvement. Her presentation and natural history of disease were similar to the 2 previously published cases. CONCLUSIONS: We present the third case of postvaccination Miller Fisher syndrome in the literature and the first associated with the novel influenza A(H1N1) vaccine.
