Likely: You are nearly 100% immune but there is always a possiblity of losing the immunity. If the doctor thinks that you are immune to hepatitis b is because you were tested for the hb surface antibody and it was present indicating that you are still immune. Precautions should still be taken as necessary and necessitated.

They now suggest booster immunization in 10 -12 years, although recent articles in Lancet suggest that this may not be necessary, and that in most instances immunity is life-long
