Safety of influenza and H1N1 vaccinations in patients with myasthenia gravis, and patient compliance.

Myasthenia gravis (MG) exacerbations may be triggered by infections.In the winter of 2009/2010, the Israeli Ministry of Health recommended that each individual with a chronic condition be vaccinated against both the seasonal influenza and the H1N1 virus. We examined vaccination practices in 74 MG patients. Only 38 patients (51.4%) received the seasonal influenza vaccine, and 24 (32.4%) received the H1N1 vaccine. No exacerbation of MG was found, and therefore seasonal influenza and H1N1 vaccines seem to be safe in MG.
