There is a difference between the vaccine given before a bite and a vaccine given afterwards. I was given the rabies vaccine, along with immune globulin shots post dog bite in 1988. It was a series of immune globulin shots around the wound and then a several shots in the arm spanning over a few weeks. I will never need any more shots. I believe dog catchers etc are given shots pre dog bite that work a little differently, I do not know if they require a booster, but I am pretty sure they do.

At the time that I was given the vaccine in Washington state no one really knew how to give it since it was so uncommon. they consulted doctors in other states and even a veterinarian lol
