Countries with a low risk of hepatitis B (HB) lack data on the effectiveness of universal HB vaccination programs for children. British Columbia began a program in 1992, offering HB vaccination to 11 year olds. We conducted an anonymous, unlinked serologic survey 7 years later, analyzing a random sample of specimens (n = 1215) from women aged 15-44 years who had undergone antenatal rubella testing. Among those aged 15-19 years inclusive there was no evidence of chronic HB (HB surface antigen), the proportion with evidence of acute HB (anti-HB core antibody) was only 0.6% (compared with 6.5% for the entire sample), and evidence of protective immunity was strong: the prevalence of anti-HB surface antibody (anti-HBs) was 79.1% (compared with 41.4% for the entire sample) and the geometric mean titre was 34.9 IU/mL (compared with 0.6-0.8 IU/mL for the older groups [p < 0.001]).
乙肝（HB）低风险国家缺乏针对儿童的普遍乙肝疫苗接种计划有效性的数据。不列颠哥伦比亚省于1992年启动了一项计划，为11岁儿童提供乙肝疫苗接种。7年后，我们进行了一项匿名、无关联的血清学调查，分析了15至44岁接受产前风疹检测的女性的随机样本（n = 1215）。在15至19岁（含15岁和19岁）的人群中，没有慢性乙肝（乙肝表面抗原）的证据，有急性乙肝证据（抗乙肝核心抗体）的比例仅为0.6%（整个样本为6.5%），且保护性免疫证据充分：抗乙肝表面抗体（抗-HBs）的患病率为79.1%（整个样本为41.4%），几何平均滴度为34.9 IU/mL（老年组为0.6 - 0.8 IU/mL [p < 0.001]）。
