?????? Huh???? According to CDC data (the most recently available figures), vaccination rates are, overall, on the upswing. What figures are you looking at? Or are people consenting to more vaccines but just not DTaP?
The state-by-state exemption rates are pretty low, overall, and not even indicative of who is forgoing the DTaP vaccine. (Some parents may seek exemptions only from certain diseases, e.g. varicella, Hep B, and Hep A).
Well, it focuses on one case in Michigan...hardly supporting your statement in Post 8 that "pertussis rates are highly correlated with vaccine rates."
Plenty of undisputed examples were provided to you in Post #163 of this thread indicating quite the contrary.
This one is problematic for making your case because it accounts for pertussis cases when DTP was still in use, which despite its egregious reputation for side effects, was likely was a stronger vaccine than the current DTaP. Also, the studies that I referenced in that same thread that I just linked were conducted in the late 1990s, when we first saw evidence of vaccine-resistent pertussis. The study that you're referencing accounts for cases before that time.
Also, do a search on Daniel Salmon and Merck. While that doesn't necessarily invalidate a study, it's important for the public to be aware of conflicts of interest.
