简要总结

Globally, hepatitis B virus (HBV) infection is the most common form of chronic hepatitis. There are still a lot of uncertainties on how infants acquired HBV leading to the development of chronic HBV infection despite active and passive immunoprophylaxis. The investigators would like to carry out a prospective study to answer the following questions:

  1. the paternal, maternal and obstetric factors leading to immunoprophylaxis failure
  2. the prevalence of immunoprophylaxis failure in Hong Kong
