Being on TAF 25 for 3.5 yrs,does an healthy adult(Hbsag +ve,Hbeag -ve,HBV DNA -ve,LFT normal,CBC normal etc.) have chance of transmission of Hep B to his partner if the latter one is not vaccinated before indulging in sex?Assuming the man is an inactive hep b carrier right from his birth with no symptoms of the disease so far.
