4 doses of anti rabies vaccine protection period in days of exposure again? then again take the shots of vaccine?

Difficult question: depends on type of rexposure, was it bite? is the animal around? so it can be kept under observation for the 10 dayy period, is the animal vaccinated? at any rate the vaccine won't work except after at least 3 - 4 weeks from the last dose, given your case: get the antirabies immunoglobulin, restart the schedule, excercise caution, check this site http://www.who.int/mediacentre/factsheets/fs099/en/
