Guillain-Barré is an autoimmune disease. It's an illness where your body's own immune system is tricked into attacking itself, and in this case it attacks your peripheral nerves so you become paralyzed, basically. That paralysis can be for weeks, or on occasion it can be permanent. So it is something that you definitely want to avoid, but quite frankly, if you go through regular influenza, you're going to see on the order of one in 100,000 cases of it.
I think you counter bad information with good information, and you publicize it.
