Posted By Katiem hi there, I believe that there is a bit of a re-think on this at the moment. Sometime ago I had my Hep B vaccination, but failed to keep up my booster. On consultation with my Occupational Physician I was told that I no longer needed a booster and that the immunity that I received on vaccination should be adequate if I were exposed to Hep B again. If you are lucky enough to have an Occ Phys then you should consult them, or your GP. Your titre level will vary. This might not help you but tit gets you and idea of the type of advice going round.
