Abstract

Belarus conducted a representative, national hepatitis B serosurvey to evaluate the impact of hepatitis B vaccination programme.

We used a multi-stage cluster design to select 3783 children born between 2009 and 2015. We collected demographic and immunization data, as well as venous blood samples, which were analysed for HBsAg by ELISA.

Out of 2870 participants with valid test results, one tested positive for HBsAg, resulting in a weighted seroprevalence of 0.02% (one-sided 95% upper bound = 0.09%). Of the 3731/3783 (99%) participants with immunization records, 86.8% (95% CI: 84.8; 88.6) had received a timely birth dose of hepatitis B vaccine and 85.6% (95% CI: 83.5; 87.4) had received a birth dose and at least two subsequent doses of the vaccine.

This study findings demonstrated the achievement of the regional hepatitis B control targets and significant progress toward the elimination of hepatitis B as a public health threat in Belarus.

进行乙型肝炎血清调查，以验证白俄罗斯实现了区域乙型肝炎控制目标

白俄罗斯进行了一项有代表性的全国乙型肝炎血清调查，以评估乙型肝炎疫苗接种方案的影响。我们采用多阶段聚类设计，选取了2009年至2015年间出生的3783名儿童。我们收集了人口统计和免疫数据，以及静脉血样本，用ELISA分析HBsAg。在具有有效检测结果的2870名参与者中，1名HBsAg检测呈阳性，导致加权血清阳性率为0.02%（单侧95%上限= 0.09%）。在3731/3783（99%）有免疫记录的参与者中，86.8% (95% CI: 84.8；88.6)和85.6% (95% CI: 83.5；（87.4）已接种了一剂出生疫苗和至少两剂后续疫苗。这项研究结果表明，白俄罗斯实现了区域乙型肝炎控制目标，并在消除作为公共卫生威胁的乙型肝炎方面取得了重大进展。
