Background The outbreak of influenza A (H1N1) pandemic during the year 2009 led to the development of several vaccinations against H1N1 virus. In Finland, 2.6 million citizens were vaccinated during pandemic 2009 – 2010 with adjuvanted influenza vaccine, Pandemrix ® . Clinical Presentation In this case report, we describe a patient with non‐paraneoplastic Lambert–Eaton myasthenic syndrome following Pandemrix ® vaccination. Conclusion Development of various autoimmune diseases in genetically predisposed subjects following exposure to certain environmental factors, including vaccinations, is a well‐known entity. Clinicians should be aware of the possibility of the induction of autoimmune diseases following vaccinations and actively ask the relevant clinical history in a newly diagnosed patient with an autoimmune disorder.
