OK, but you can get GBS from pretty much any viral syndrome. After all, it's an auto-immune reaction to a virus, usually weeks after the fact. I doubt I'd let the threat of GBS dissuage me from the relatively good coverage of most vaccines, ESPECIALLY if this turns out to be bad.

Personally, as a physician, I'm waiting to see what's going to happen. No point panicking, when there's enough crap out there making patients already.
