目标：只有父母允许孩子接种疫苗，才能通过免疫消除和控制儿童疾病。为了了解与脊髓灰质炎疫苗犹豫相关的社会网络因素，我们根据印度马莱冈的疫苗接受状况调查了家庭的社会和空间聚集情况，该地区以拒绝接种疫苗和反复发现脊髓灰质炎病例而闻名。方法：我们于 2012 年 7 月采访了 25 个社区的 2462 个家庭的户主，并根据其他家庭的建议构建了社交网络。我们将主要分析范围限制在被调查家庭，我们还拥有有关他们是否为其符合条件的孩子接受脊髓灰质炎疫苗的数据。结果：保留了 2452 个家庭的数据，这些家庭在 2012 年对 830 个家庭进行了提名。拒绝疫苗家庭的外出联系少于接受疫苗家庭。排除 24 个隔离家庭后，与接受疫苗的家庭相比，拒绝疫苗家庭对其他拒绝疫苗家庭的提名多出 189%（网络最大组成部分多出 93%），这表明拒绝疫苗家庭在社交网络中聚集。由于大约一半的联系将社区内的家庭联系在一起，因此拒绝疫苗的群体位于空间局部的“口袋”中。结论：可以利用拒绝疫苗家庭的社会（和空间）集群来制定沟通策略，以提高疫苗接受度和社区对脊髓灰质炎和其他疫苗可预防疾病的免疫计划的认知。 (C) 2016 年由爱思唯尔有限公司出版。
Objectives: Eradication and control of childhood diseases through immunization can only work if parents allow their children to be vaccinated. To learn about social network factors associated with polio vaccine hesitancy, we investigated social and spatial clustering of households by their vaccine acceptance status in Malegaon, India, an area known for vaccine refusal and repeated detection of polio cases.Methods: We interviewed family heads from 2462 households in 25 neighborhoods in July 2012 and constructed social networks based on advice seeking from other households. We restricted our main analyses to surveyed households for which we also had data on whether they accepted the polio vaccine for their eligible children or not.Results: Data from 2452 households was retained and these households made 2012 nominations to 830 households. Vaccine-refusing households had fewer outgoing ties than vaccine-accepting households. After excluding 24 isolated households, vaccine-refusing households had 189% more nominations to other vaccine-refusing households (93% more in the largest component of the network) compared to vaccine-accepting households, revealing that vaccine-refusing households cluster in the social network. Since roughly half of all ties connect households within neighborhoods, vaccine-refusing clusters lie in spatially localized "pockets".Conclusions: The social (and spatial) clustering of vaccine-refusing households could be leveraged to tailor communication strategies to improve vaccine acceptance and community perceptions of immunization programs for polio and other vaccine-preventable diseases.
