Vaccine Hesitancy Among Caregivers in China: Associations of Misinterpreted AEFI, Compensation Awareness, and Institutional Trust.
Article in Vaccines, 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
backgroundVaccine hesitancy remains a major global public health challenge despite high immunization coverage. While concerns about adverse events following immunization (AEFI) are widely recognized, limited attention has been paid to caregivers' ability to distinguish vaccine-related adverse reactions from coincidental illnesses, as well as to the associations of compensation awareness and institutional trust with vaccination decisions.
methodsA cross-sectional survey was conducted between January and March 2025 among 3497 caregivers of children aged 0-6 years using multistage random sampling. Data were collected on AEFI knowledge (including understanding of coincidental illnesses), compensation mechanism awareness, institutional trust, and vaccination behaviors. Vaccine hesitancy was assessed using a self-reported measure and the WHO SAGE Vaccine Hesitancy Scale (VHS). Multivariable linear regression models were used to estimate factors associated with hesitancy scores.
resultsThe prevalence of vaccine hesitancy was 8.6%, with a mean VHS score of 23.2 ± 4.2. Although general awareness of AEFI reached 90.0%, correct understanding of coincidental illnesses was only 25.7%. Higher AEFI knowledge and compensation awareness were associated with lower hesitancy scores, whereas distrust in compensation mechanisms and perceived vaccine unsafety were associated with higher hesitancy. Coverage of national immunization program (NIP) vaccines exceeded 90%, while uptake of self-paid vaccines varied from 46.7% to 89.7%.
conclusionsVaccine hesitancy among caregivers was associated with cognitive understanding, economic considerations, and institutional trust. Limited understanding of coincidental illnesses may be associated with increased concerns about vaccine safety, while compensation awareness and institutional trust were associated with lower levels of vaccine hesitancy. Strengthening communication on AEFI causality and improving transparency of compensation policies may help reduce vaccine hesitancy and support immunization programs in settings with mixed public-private financing systems.
