Decreasing hepatitis B seroprevalence in pregnant women in Taiwan between 2016 and 2021: a claim-based cohort study

The implementation of national vaccination programs has demonstrated significant success in reducing HBV seroprevalence among pregnant women, which is particularly evident in the substantial decrease in HBsAg seroprevalence in Taiwan post-July 1986. These findings emphasize the importance of continued and consistent vaccination efforts, supporting the need for ongoing public health strategies to combat HBV infections effectively.
