Parental decision making about childhood vaccinations is complex and multidimensional. There is a perception that the number of parents having concerns regarding childhood vaccinations has been increasing in Canada. The aim of this study was to explore vaccine hesitancy among Canadian parents and to examine factors associated with a parent's intention to vaccinate his/her child. Informed by the Theory of Planned Behaviour (TPB) this study assesses potential associations between parents' knowledge, attitudes and beliefs toward vaccination and their intention to vaccinate their child in the future. A national sample of Canadian parents of children aged 24-59 months (N = 2013) was surveyed using an online survey methodology. Half of the surveyed parents strongly intended to have their child vaccinated in the future. Parents' information needs and searches as well as parents' trust in different institutions were associated with intention to vaccinate. Parents who reported having frequently looked for vaccine information, who considered that it was their role as parents to question vaccines, or who had previously experienced difficulty accessing vaccination services were less likely to strongly intend to vaccinate their child in the future. Parents who had a high level of trust in doctors and public health were most likely to strongly intend to vaccinate their child. Results of the multivariate analysis showed that positive attitudes (aOR = 8.0; 95% CI: 6.0, 10.4), higher perceived social support (aOR = 3.0; 95% CI: 2.3, 3.93), and higher perceived behavioural control (aOR = 1.8; 95% CI: 1.4, 2.43) were associated with parents' intention to vaccinate their child. Findings of this study suggest that trust-building interventions that promote pro-vaccine social norms and that address negative attitudes toward vaccination could enhance vaccine acceptance among Canadian parents.
父母在儿童疫苗接种方面的决策是复杂且多方面的。人们认为，加拿大对儿童疫苗接种有顾虑的父母人数一直在增加。本研究旨在探讨加拿大父母对疫苗接种的犹豫态度，并研究与父母为子女接种疫苗的意愿相关的因素。本研究以计划行为理论（TPB）为指导，评估了父母对疫苗接种的知识、态度和信念与其未来为子女接种疫苗的意愿之间的潜在关联。通过在线调查方法对 24-59 个月儿童的加拿大父母进行了一项全国性抽样调查（N=2013）。一半接受调查的父母强烈希望为孩子接种疫苗。父母的信息需求和搜索以及父母对不同机构的信任与接种意愿有关。报告经常寻找疫苗信息的父母、认为父母有责任质疑疫苗的父母，或之前曾经历过难以获得疫苗接种服务的父母，未来不太可能强烈希望为孩子接种疫苗。对医生和公共卫生机构高度信任的父母最有可能强烈希望为孩子接种疫苗。多变量分析结果表明，积极的态度（OR=8.0；95%CI：6.0，10.4）、更高的感知社会支持（OR=3.0；95%CI：2.3，3.93）和更高的感知行为控制（OR=1.8；95%CI：1.4，2.43）与父母为子女接种疫苗的意愿有关。本研究结果表明，建立信任的干预措施可以促进支持疫苗接种的社会规范，并解决对疫苗接种的负面态度，从而提高加拿大父母对疫苗的接受程度。
