I am not an expert on GBS, however I have one family member and one church friend who suffered GBS after receiving the flu vaccine. GBS is rapid onset progressing from the feet to the head. Both of these people ended up in the hospital on ventilators, undergoing platelet washing procedures, and required extensive rehabilitation. They both recovered, but the family member has residual facial paralysis. GBS does not wax and wane, it's sudden, fast, and progressive. I don't recall anyone on this thread having a problem with GBS.
