Do you build up any kind of immunity after repeated exposure?

  It's a bacterial infection, so I believe immunity just doesn't last as long as it does for e.g. chicken pox. The vaccine, when it was available, recommended rather short intervals between boosters.

  Nope. On the bright side, the treatment is easy if it's not neglected . There's little chance of any residual too.
