In brief: Depends on shots
The normal recommendation is shots at 0, 1 and 6 months.
However, there is a 5percent failure rate of the vaccine. If it has been more than a year, you should start over.You should also get an antibody for hepatitis b which will show if the vaccine caused you to be immune or not.
