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.
