Researchers established that parental vaccination status often predicts that of their children, but a limited number of studies have examined factors influencing dyadic concordance or discordance (i.e., same or different vaccination status or intent for both members). We investigated how child versus parent age as well as parents' perceptions of their respective friends' immunization behavior impacted un/vaccinated parents' decisions regarding vaccinating their child. An online survey obtained the COVID-19 vaccination status and views of 762 parents of 5-17-year-old children. More than three-quarters of all dyads were concordant; 24.1% of vaccinated parents would not vaccinate their child, with greater hesitancy for younger children and among younger or less educated parents. Children of vaccinated parents and of parents who thought most of their child's friends were vaccinated were 4.7 and 1.9 times, respectively, more likely to be vaccinated; unvaccinated parents were 3.2 times more likely to accept the vaccine for their child if they believed most of their friends would vaccinate their children. Further, parents who reported that most of their friends were vaccinated were 1.9 times more likely to have obtained the vaccine themselves, illustrating the influence of social norms. Regardless of their own vaccination status, parents of unvaccinated children were more likely to be politically conservative. If communities or circles of friends could achieve or convey a vaccinated norm, this might persuade undecided or reluctant parents to vaccinate their children. Future research should examine the effects of community behavior and messages highlighting social norms on pediatric vaccine uptake.
研究人员证实，父母的疫苗接种状况往往能预测其子女的接种状况，但仅有少数研究考察了影响二元一致性或不一致性（即两人的疫苗接种状况或接种意愿相同或不同）的因素。我们调查了孩子与父母的年龄差异，以及父母对其各自朋友免疫行为的看法如何影响已接种/未接种疫苗的父母为孩子接种疫苗的决定。一项在线调查获取了762名5至17岁孩子的父母的新冠疫苗接种状况和观点。超过四分之三的二元组情况一致；24.1%的已接种疫苗的父母不会为其孩子接种疫苗，对年龄较小的孩子以及年龄较小或受教育程度较低的父母来说，这种犹豫更为明显。父母已接种疫苗的孩子，以及父母认为其孩子的大多数朋友都已接种疫苗的孩子，接种疫苗的可能性分别高出4.7倍和1.9倍；未接种疫苗的父母如果认为其大多数朋友会为自己的孩子接种疫苗，那么他们为自己孩子接种疫苗的可能性会高出3.2倍。此外，报告称其大多数朋友都已接种疫苗的父母自己接种疫苗的可能性高出1.9倍，这说明了社会规范的影响。无论自身的疫苗接种状况如何，未接种疫苗孩子的父母在政治上往往更为保守。如果社区或朋友圈能够实现或传达一种接种疫苗的规范，这可能会说服犹豫不决或不情愿的父母为其孩子接种疫苗。未来的研究应考察社区行为以及强调社会规范的信息对儿童疫苗接种率的影响。
