Being vaccinated for Hep B twice?

Is it possible for a Hepatitis B vaccine to be ineffective? Are there any risks to being vaccinated twice?

I just had a standard STD test done, and was told my something-or-other levels are low ("below 1") which indicates that I have not been vaccinated for Hep B, and should do so.
I distinctly remember being vaccinated, though. There was a big campaign in 7th grade back in the early 1990s, complete with a little video that I still remember: "Hepatitis B is a real bad rap". I am really almost 100% sure I got the shots. They told me it was very unlikely I had been vaccinated given my test results.
At their recommendation I booked an appointment to go ahead with the tests. Is there anything for me to worry about? Suppose they screwed something up and I have already been vaccinated after all, is there any risk to doing it again? Or should I just relax and go ahead?
