Summary
Prevention of perinatal transmission is essential to decrease the global burden of chronic
HBV. Recombinant HBV vaccine and hepatitis B immunoglobulin (HBIG) given after delivery to
the newborns of HBsAg positive mothers is the standard of care for prevention of HBV in
babies. Some studies have however, shown that vaccine alone may be equally effective. Hence,
immunoprophylaxis with hepatitis B vaccine with or without HBIG is effective in prevention
of transmission of overt HBV infection to the babies. The primary outcome measure of most of
the trials on immunoprophylaxis was the occurrence of hepatitis B, defined as a blood
specimen positive for hepatitis B surface antigen (HBsAg). However, whether this
immunoprophylaxis also prevents HBsAg negative HBV infection (occult HBV infection) in
babies is not known. In the present study the investigators evaluated the efficacy of the
two regimens; vaccination alone and compared it with vaccination plus HBIG administration at
birth in preventing transmission of both overt and occult HBV infection to the newborn
babies.
