Vaccine-preventable-diseases are major contributors to disease burden in Sub-Saharan Africa. There is dearth of knowledge on the drivers of childhood vaccine hesitancy in Nigeria and its impact on coverage. Although understudied, pregnant women are a particularly important vulnerable group and very relevant for childhood vaccination decisions. This study's aims are to adapt Confidence, Complacency, Constraints, Calculation, and Collective Responsibility, also known as the 5C psychological antecedence scale for the Nigerian context and to measure predictors of intention to vaccinate among pregnant women (prenatal) and subsequent vaccination behavior (postnatal). It is a longitudinal study that used multi-stage sampling procedure. One healthcare facility was selected from each district in five regional clusters, from which 255 pregnant women were randomly drawn. A standardized questionnaire was used to collect relevant data, including the 5C and some additional variables. Multiple linear regression using backward elimination analysis was performed to identify intention at prenatal and behavior at postnatal. Pregnant women's intention to vaccinate unborn children was lower if they were Muslims, had lower confidence in public health system, if husband approval was important, and if they believed in rumor. At postnatal, vaccination behavior was more likely to follow mothers' religious beliefs, when confidence in vaccine effectiveness was high and when mothers felt responsible for the collective. However, everyday stress (constraints) related to less vaccination behavior, and intention did not predict actual vaccination behavior. The 5C scale needs revision before being widely used in Nigeria. Yet, it is a better tool for measuring vaccination behavior than intention.
疫苗可预防疾病是撒哈拉以南非洲地区疾病负担的主要成因。在尼日利亚，人们对儿童疫苗犹豫的驱动因素及其对疫苗接种覆盖率的影响知之甚少。尽管研究不足，但孕妇是一个特别重要的弱势群体，对儿童疫苗接种决策非常关键。本研究的目的是针对尼日利亚的情况，改编信心、自满、限制、算计和集体责任（即5C心理先行量表），并测量孕妇（产前）接种疫苗的意愿预测因素以及随后的接种行为（产后）。这是一项采用多阶段抽样程序的纵向研究。从五个区域集群的每个区中选择一个医疗机构，从中随机抽取255名孕妇。使用标准化问卷收集相关数据，包括5C量表和一些其他变量。采用向后排除分析的多元线性回归来确定产前意愿和产后行为。如果孕妇是穆斯林、对公共卫生系统信心较低、丈夫的批准很重要以及她们相信谣言，那么她们为未出生孩子接种疫苗的意愿就较低。在产后，当对疫苗有效性的信心较高且母亲们感到对集体负有责任时，接种行为更有可能遵循母亲的宗教信仰。然而，与较少接种行为相关的日常压力（限制因素）以及意愿并不能预测实际的接种行为。5C量表在尼日利亚广泛使用之前需要修订。然而，它在测量接种行为方面比意愿是一个更好的工具。
