Examining wealth-related inequality in childhood vaccination in Fiji using the UNICEF Multiple Indicator Cluster Survey 2021.
Article in International health, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundDespite 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.
methodsData 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.
resultsOut 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.
conclusionsOur results help guides policy decisions on the delivery of immunisation services, enabling more equitable childhood immunisation in Fiji.
