The length of time between my hepatitis b series was greater than when each were supposed to be taken (now need titer).were all shots still effective?

Probably effective: If one is doing a blood titer test, the result will decide if she is immune or not immune. The shot schedule in the past won't matter anymore. Everybody with close or frequent contact with a hep b carrier (especially healthcare workers) should have their titers tested. Some people who get the shots at exactly the recommended time can still have very low titers, and need additional booster shots.
