It is reasonable to question the efficacy of the Tdap vaccine to prevent pertussis when it does not seem to prevent pertussis even after 5 vaccinations in 5 years. The question that no one seems to be asking is there any reason why the vaccines for tetanus and diptheria are also given repeatedly. Why can't the vaccine manufacturers make a pertussis only booster?
