>The vaccine is to the toxin produced by the bacteria, not to the bacteria itself; supposedly, by the time the body manages to kill the bacteria (even if already recognized by the immune system), there is too much toxin in the system. I'm not an immunologist, but I don't think you're correct here. >It is administered, and is likely working, but never went through the rigorous testing we now do for vaccines; furthermore, after it was introduced, tetanus incidence decreased considerably also in places that did not use a vaccine. The history of the tetanus vaccine is not what I expected when I started looking at it. Deaths worldwide from Tetanus didn't decrease substantially until the 80s when the vaccine starting being administered everywhere. So don't know what you're talking about.
