Who is at risk of developing Guillain-Barre syndrome (GBS)?

Anyone can develop GBS, but it is more common among adults than children. The incidence of GBS increases with age, and people over age 50 are at greatest risk for developing GBS. Each year, on average, about 3,000 to 6,000 people in the United States develop GBS whether or not they received a vaccination – that’s 1 to 2 people out of every 100,000 people.
