Flu vaccination and Guillain-Barré Syndrome


  • The study found no evidence for an association between influenza vaccination and development of Guillain-Barré Syndrome.

Why this matters ?

  • Guillain-Barré Syndrome (GBS) is usually preceded by infection.

  • Stimulation of the immune system by vaccination may be sufficient to induce GBS.

  • Several studies have reported an increased incidence of Guillain-Barré Syndrome in people who received the 1976 and 2009 influenza vaccinations.
