Abstract

Background: Despite a 95% immunisation rate in Fiji, disparities exist in the distribution of immunisation in children from different socioeconomic backgrounds. We used data from the 2021 Fiji Multiple Indicator Cluster Survey (MICS) to determine socioeconomic inequalities contributing to differences in immunisation coverage.

Methods: Data were extracted from the 'Household', 'Fertility/Birth history' and 'Children under 5' modules from the 2021 Fiji MICS to determine wealth quintiles and calculate vaccination rates for children aged 12-23 mo. Logistic regression was performed with factors of interest. Erreygers' corrected concentration index (ECI) was calculated and used to measure socioeconomic inequality.

Results: Out of 417 children; 85.6% (357/417) were fully immunised, 12.0% (50/417) partially immunised and 2.4% (10/417) had no immunisations. Factors associated with increased probability of being fully immunised included being in the highest wealth quintile after adjusting for the number of children in the household. Children from larger households were more likely to be partially immunised after adjusting for household wealth. The ECI for fully vaccinated children was positive, whereas the ECI was negative for partially vaccinated children. Logistic regression also indicated a pro-rich inequality in vaccination.

Conclusions: Our results help guides policy decisions on the delivery of immunisation services, enabling more equitable childhood immunisation in Fiji.

利用联合国儿童基金会2021年多指标类集调查，审查斐济儿童疫苗接种中与财富相关的不平等现象。

背景：尽管斐济的免疫接种率达到95%，但不同社会经济背景的儿童的免疫接种分布存在差异。我们使用了2021年斐济多指标类集调查（MICS）的数据来确定导致免疫覆盖率差异的社会经济不平等。方法：从2021年斐济多指标类集调查的“家庭”、“生育/出生史”和“5岁以下儿童”模块中提取数据，以确定财富五分位数并计算12-23个月儿童的疫苗接种率。对感兴趣的因素进行Logistic回归。计算了埃雷格斯修正浓度指数（ECI），并用它来衡量社会经济不平等。结果：417例患儿中；85.6%（357/417）完全免疫，12.0%（50/417）部分免疫，2.4%（10/417）未免疫。与充分免疫的可能性增加相关的因素包括，在调整了家庭中子女的数量后，处于最高财富的五分之一。根据家庭财富进行调整后，大家庭的孩子更有可能部分免疫。完全接种疫苗的儿童ECI为阳性，而部分接种疫苗的儿童ECI为阴性。Logistic回归也表明在疫苗接种方面存在亲富不平等。结论：我们的研究结果有助于指导有关提供免疫服务的政策决定，使斐济的儿童免疫接种更加公平。
