I will clarify bberry ,

a person is exposed to hepatitis B, immeadiately he got tested for Hbsag which indicated as -ve. He took 3 vaccine series and got positive titres of antibodies.
what my question is if a person is exposed to Hepatitis B and not infected and immunised , will his DNA contain some copies or IU/mL in his Blood? if a person is exposed to virus means Anti-HBC is always positive, even he clears it or not? I assume that his DNA should contain very very very minimum copies or IU/mL which only very highly sensitive PCR test can detect . Is my assumtion rt?

i dont get the question.. what do u mean "how long wil he have?"

to live ?
to clear?
to have til what happens exactly ?

if ur negative to hbv and positive to antibodies then it may be a case of what is called Ocult Hepatits B infection (OBI) . which is a case that needs to be followed closely by your doctor.

still, clarify your question more please
