do many of you have this as well? are you concerned like me about the potential of bioterrorism... I know that I develop NO immunity after immunizations! I've been tested to 0 titres after recieving shots. I'm not overly worried but we are after all a large section of society and what happens when this stuff does come to pass....? Have any of you been tested for immune dysfunction and what if anything are you doing about it>? Anyone here tried IvIg??? did it help? Good luck ya'll!
