I wouldn't be surprised if you get some resistance towards the Hep B vaccine unless the doctor knows you're in what is considered a high-risk group. The reason for this is that the vaccination requires a total of 4 shots - the first three are given in one month intervals, and then a final one a year after the 3rd. Because of this, there's a high rate of people not following through and getting all the required shots.
