What is Guillain-Barre Syndrome?
Normally, about one person per 100,000 people per year will develop Guillain-Barre Syndrome (GBS), an illness characterized by fever, nerve damage and muscle weakness. In 1976, vaccination with the swine flu vaccine was associated with getting GBS. Several studies have been done to evaluate if other flu vaccines since 1976 were associated with GBS. Only one of the studies showed an association. That study suggested that one person out of 1 million vaccinated persons may be at risk of GBS associated with the vaccine.
