Myasthenia Gravis

Flu vaccine



is the flu vaccine safe for people with myasthenia gravis symptoms mild and not medicated but have muscle weakness when tired

I believe the flu shot is safe for my patients, especially the ones on immunosuppression, but I direct them toward the inactivated (dead)formulation. Patients with immunosuppression (steroids, IVIG, cellcept, imuran, etc) used to treat myasthenia gravis should avoid live virus vaccines. Talk about it with your physician.
