This study assesses the prevalence of Vietnamese children receiving the hepatitis B (HepB) vaccine birth dose and explores its associated socioeconomic factors.
We used the data of the Multiple Indicator Cluster Survey, 2014. We estimated the overall percentage of HepB birth dose vaccination among 0-23-month-old children and its percentages according to selected characteristics. Multiple logistic regression was applied.
62.8% of children received the HepB vaccine birth dose. The prevalence rates by selected factors ranged from 35.3% to 76.7%. The categories with the lowest prevalence rates were children who had low birth weight (41.6%), had a mother aged less than 20 years (35.3%), had a mother with primary or less education (42.7%), belonged to ethnic minorities (30.3%), resided in rural areas (59.9%), and were in the 1 quintile of mother's socioeconomic status (38.6%). Receiving HepB vaccine birth dose was associated with child's birth weight, mother's age, mother's education, socioeconomic status, and ethnicity.
This study identified vulnerable groups, upon which policy-makers should focus their efforts to equitably and sustainably tackle birth dose HepB vaccine coverage as well as the full vaccination coverage, thereby promoting long-lasting herd immunity in this country.
本研究评估了越南儿童接受乙型肝炎（HepB）疫苗基础剂量的情况，并探讨了其相关的社会经济因素。
我们使用了 2014 年多指标类集调查的数据。我们估计了 0-23 个月大儿童中 HepB 基础剂量疫苗接种的总体百分比及其根据选定特征的百分比。应用了多因素逻辑回归分析。
62.8%的儿童接受了 HepB 疫苗基础剂量接种。按选定因素划分的流行率范围为 35.3%至 76.7%。流行率最低的类别包括出生体重低（41.6%）、母亲年龄小于 20 岁（35.3%）、母亲受教育程度为小学及以下（42.7%）、属于少数民族（30.3%）、居住在农村地区（59.9%）和母亲社会经济地位处于第 1 五分位数（38.6%）的儿童。接受 HepB 疫苗基础剂量接种与儿童的出生体重、母亲的年龄、母亲的教育程度、社会经济地位和种族有关。
本研究确定了弱势群体，决策者应集中精力，努力公平和可持续地解决基础剂量 HepB 疫苗接种覆盖率以及全面疫苗接种覆盖率问题，从而在该国促进持久的群体免疫。
