I wonder if the hep b vaccine is setting the stage for more kids to develop PANDAS? I know my PANDAS dd even got an "extra" hep b vaccine as a baby (due to switching medical groups).
note: The hep B vaccine is on the CDC schedule in the US starting at birth...which is crazy b/c it's a sexually transmitted disease.
