Abstract

In a randomized, controlled trial, 105 healthy full-term infants born to HBsAg and HBeAg positive mothers received three doses (at 0, 1 and 6 months) of either a new recombinant hepatitis B vaccine (Hepavax-Gene) or Engerix-B. Both groups were also given hepatitis B specific Hepa-big immunoglobulin (HBIG) within 24h of birth. Levels of antibodies to hepatitis B surface antigen (anti-HBs) were assessed on days 30, 60, 210, 360, and 2 years post-vaccination. Efficacy and immunogenicity and safety of the two vaccines were not significantly different; both vaccines achieved >94% seroprotection within 360 days. At 2 years, only one subject (1.9%) in the Hepavax-Gene group and two subjects (3.9%) in the Engerix-B group were HBsAg positive. No serious adverse events (AEs) were observed in either group.
