A 27-year-old male asked:

Already been vaccinated for rabies why do you have to get a booster if bitten again? does the original dose not offer lasting immunity?

To boost: the existing immunity. With time the immunity wanes and a new booster dose will boost the already existing immunity

Depends on whether you received the vaccine or the immune globulin.

Boosters to boost: immunity. The boosters are given because there is not treatment for the rabies infection and it's nearly always fatal once the onset of symptoms. Given that fact, better to boost the immunity by giving another series (only 2 injections the second exposure), if it prevents disease and death. http://www.cdc.gov/vaccines/hcp/vis/vis-statements/rabies.html#who
