To evaluate the efficacy of combined vaccination with 200IU dose of HBIG and 20 μg of anti-HBV vaccine for the prevention of HBV vertical transmission in babies delivered by HBeAg + and highly viremic mothers and the HBV markers' dynamic changes in babies during follow-up.


HBeAg + mothers with HBV DNA ≥ to 1.0 × 6 log(10) copies/ml were enrolled and their babies were followed up until 12 months old. The infants received HBIG 200 IU IM in 24 hrs and on day 15, and 20 μg recombinant anti-HBV vaccine at 0, 1 and 6 months. The HBV markers and HBV DNA were tested at birth day, and 1, 7, 12 months after birth respectively. The vertical transmission rate at birth and intrauterine infection rate, the HBsAb positive rate and the HBV markers' dynamic changes during follow up were evaluated.


(1) 29 out of 127 infants with HBsAg (+) at birth, 11 of which were HBV DNA (+), HBV perinatal transmission rate was 22.83%. 2 infants' HBsAg were positive at month 1 and became negative at month 7 and 10 infants were still HBsAg (+) and HBV DNA (+). HBV intrauterine infection rate was 7.87%. (2) The positive rate of HBeAg and HBcAb in uninfected infants were 96.58% and 98.29% respectively, which declined gradually to undetectable level after immunization. No infants were HBeAb (+). (3) Infants uninfected produced effective HBsAb after vaccination. The level of HBsAb elevated gradually, and the level of HBeAg decreased quickly even to undetectable.


The combination vaccination of 200 IU HBIG with 20 μg recombinant anti-HBV vaccine in the Infants delivered by HBeAg (+) and highly viremic mothers reduced obviously the rate of perinatal transmission of HBV, enhanced largely the production of antibody against HBV surface antigen and dropped the maternal HBeAg and HBcAb in infants or even to negative.
