Vertical transmission of HepB from pregnant woman to fetus occur only if woman has an active form of HepB.
Look for HBeAg marker (presence of that marker indicates high level of replication and infect ivory of HepB virus). If you revealed this marker , it means there is a higher risk of vertical transmission of HepB virus from woman to the fetus.
All newborns from the mothers with active form of HepB virus are passively immunized at birth with HepB immune globulin (HBIG), followed by active immunization with recombinant HBV vaccine.
