If you dog had not finished the series, or was exposed to Bordatella prior to vaccination that could explain it.
NO vaccine is 100% effective, dog, cat OR human, however I believe they have to prove through testing that their vaccine is somewhere in the 90% range of effectiveness to market it.
Many bording kennels, obedience classes and groomers require the vaccination, and animals that are higher risk (ie. being around many other dogs) are reccomended they have this vaccine.
