I received your note / PM. I make it a habit to respond on the forum.
As to your question:
Clearance depends on the age of infection.
Do you have labs to confirm that you are free of HepB before your involvement with the individual with HepB? I ask this because, often times people check for HepB after a sexual encounter. But there is a chance that you had HepB all along but just didn't know it. This is especially true if you come from a high risk area.
