First of all no neurologist worth their salt would call GBS a "brain disorder" That it s not!! It starts as ascending paralysis from the lower limbs (the legs ) up!! Most people NEVER get the worst symptoms of not being able to breath!! Now did the good "doctor" tell you why you can get it from the "old" H1N1 (swine flu) vaccine? It is because you can get it from the H1N! flu itself and are more likely too at that!! The older vaccine was not attenuated and was made from live virus and therefore caused more of a reaction.The newer vaccine they are giving this time around is much different and will have a much less likely chance of causing ANY reaction!! If you have questions talk to your FAMILY doctor about it he will NOT lie to you!! and will gladly answer all your questions concerning both types...do not let fear prevent you from arming yourself against disease!!
