Influenza vaccination and Guillain-Barré syndrome – do the benefits outweigh the risks?


  • Influenza vaccination is not associated with an increased risk for Guillain-Barré syndrome (GBS) in older adults in Taiwan.

Why this matters

  • Influenza vaccination has previously been associated with a potential increased risk for GBS. However, upper respiratory tract such as influenza and gastrointestinal infections are the most common antecedent infections, especially in older adults.

  • Understanding the risk associated with influenza vaccination versus potential infection is important in GBS prevention and optimal care for older adults.
