Prevention of mother-to-child transmission (MTCT) of HBV is critical to eliminate chronic HBV infection. Here, we reviewed the progress toward the elimination of HBV infection in children in China in the recent decade.

The prevalence of hepatitis B surface antigen (HBsAg) was declined from around 10% among children in 1980s to 2 × 105 U/mL during the third trimester is increasing, which will further reduce MTCT of HBV.
