If u developed guillain-barre syndrome (gbs) after tdap vaccine, which autoantibodies r commonly found in vaccine-induced gbs? only ganglioside ab's?

Controversial: There is only anecdotal evidence that vaccines of any type are related to guillain-barre, and formal large studies have shown that no such relationship can be proven. Of course, many web sites, and blog sites continue to espouse multiple causes and effects which have been proven bogus in the past. Real causes include influenza a, campylobacter jejuni, and ebstein-barr virus infections.
