Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This study is a single-group, multi-center and prospective clinical study designed to assess the efficacy and safety of TAF in blocking mother-to-child transmission of hepatitis B virus.Pregnant women whose HBsAg and HBeAg are positive are included in the study.Eligible hepatitis B pregnant women are given TAF antiviral therapy at 24-28 weeks of gestation to block mother-to-child transmission and followed up during pregnancy and after delivery.The study will be initiated with approval by the central ethics committee.Subjects will start screening after signing the informed consent form. Those who meet the criteria will start taking TAF (25mg, oral, 1/day) at 24-28 weeks of gestation until one month after delivery.At that time, chronic hepatitis B carrier will stop taking antiviral therapy, and patients with chronic hepatitis B decide whether to continue the therapy according to the patient's condition.The babies born are immunized according to the national standard immunization program,, that is, 100 IU of hepatitis B immunoglobulin (HBIG) and 10 μg/0.5 ml of hepatitis B vaccine are given within 12 hours after birth. And the same dose of hepatitis B vaccine is given at 1 month and 6 months of age.
