Thanks for the link. I really like that blogger and I had already read the article she was talking about and wasn't impressed with it either. The CDC and others have made it pretty clear that the main reason there is an increase in pertussis is because of waning immunity from the new vaccine etc. However, she states in that link and in other parts of her blog that there is no doubt that unvaccinated or undervaccinated kids are also contributing to the outbreaks. They just aren't the sole cause.
@ma2two there have been studies done on kids who had febrile seizures and they are harmless. Even Paul Offit said he watched his daughter have a grand mal seizure as a reaction to the DTaP (YES, he said it was from the vaccine) and that while it was scary to watch, they really are nothing to be worried about.
