Most patients with Guillain-Barre syndrome may be vaccinated safely.

Reuters (2/4, Grens) reported a study in Clinical Infectious Diseases suggesting that most patients diagnosed with Guillain-Barré syndrome can safely receive vaccines and may not suffer flare-ups after vaccination. Previously, the Centers for Disease Control and Prevention had warned against giving flu shots to patients who developed Guillain-Barré within six weeks of a flu vaccination. In the study, 550 patients received about 1,000 vaccines, and none experienced a flare up to two months after being vaccinated. In addition, two patients who had developed Guillain-Barré within six weeks of a flu vaccination received a flu shot and did not experience a flare.
