[Interruption of perinatal transmission of HBV by Chinese recombinant hepatitis B vaccine].

Sixty-two infants who were born from HBsAg and HBeAg both positive mothers were vaccinated with 20 micrograms/dose recombinant hepatitis B vaccine, which was made in Beijing Institute of Biologic Products (Vaccinia virus recombinant hepatitis B vaccine) and Changchun Institute of Biologic Products (Chinese hamster ovary cells recombinant hepatitis B vaccine), at 0, 1, 6 months. All the babies were followed up for 9 or 12 months. The results showed that the protective rates of Beijing vaccine and Changchun vaccine were 79.2% and 80.2%, respectively, the positive rates of anti-HBs were 78.8% and 79.3%, respectively. Local or systematic reactions were not found in all the babies 3 days after injection. These results suggested that the Chinese recombinant hepatitis B vaccine was safe and effective. It was better than the plasma vaccine with the same dose.
