ELI5: why does vaccinating for rabies work after exposure when it doesn’t with other diseases?

When you get bit by something you’re supposed to get a whole bunch of vaccinations incase it was rabid, why does that work if the individual had already been exposed to rabies when they were initially attacked?

Rabies has a long incubation period. The virus can be in your bloodstream for a couple of weeks before it reaches your brain. If you get vaccinated within 10 days of exposure, you can stop the infection from impacting the brain.

Anyways, rabies is far from the only disease managed with post-exposure treatment. Anyone who has ever stepped on a rusty nail and then received a tetanus shot can tell you that much.
