Boulder Q: Why shouldn people who have had Guillan-Barre disease get a flu shot?
We think that Guillan-Barre syndrome is a post-viral infection abnormality, possible due to autoimmunity. Because of this, many doctors are reluctant to give a “live” virus vaccine to someone with G-B history. Flu vaccine (injected) is not live, but there are reports of G-B in people after flu shots anyway, so we tend not to do it, as a precaution against a very rare event.
