Health beliefs model and vaccine acceptance: insights from the COVID-19 pandemic among non-medical personnel in Mwanza, Tanzania.
Article in BMC public 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
backgroundWithout vaccine, attaining herd immunity remains a global challenge. While medical personnel have been a focus of vaccine promotion and immunization improvement, non-medical personnel (NMPs) working in hospital settings remain understudied in Tanzania. Given their routine interaction with patients and healthcare workers, NMPs can play a crucial role in the transmission of infections. This study aimed to assess vaccine acceptance level in this vulnerable, predisposed population using the health belief model (HBM) as a guiding frame to obtain insights from the COVID-19 vaccine in Tanzania.
methodsA total of 203 purposively selected NMPs from three randomly selected health facilities in Mwanza City were involved in a cross-sectional study. A validated self-administered questionnaire was used to collect data. Descriptive statistics were presented using counts and percentages. Multivariate logistic regression was used to determine the association between sociodemographic, lifestyle behaviors, and health belief constructs with vaccine acceptance. Associations were reported using odds ratios with 95% confidence intervals at p < 0.05.
resultsThe overall COVID-19 vaccine acceptance was 16.75% despite 62.07% of NMPs indicating willingness to vaccinate. Hesitancy was 65% primarily due to lack of information (19.21%), fear of side effects (17.73%), and concerns about vaccine safety (16.25%). Perceived threats (aOR: 9.89, p = 0.01), perceived barriers (aOR: 8.83, p = 0.02), and cues to action (aOR: 1.45, p = 0.05) were significantly associated factors of vaccine acceptance among NMPs.
conclusionVaccine acceptance among NMPs in Mwanza remains low due to fear, doubts and limited information. HBM provides a robust framework for understanding vaccine-related behavior. Policymakers should implement structured risk communication, workplace vaccination initiatives and engage NMPs as “vaccine champions”, using HBM strategies to improve uptake and public health advocacy.
