Exploring factors affecting malaria vaccination intention and COVID-19 vaccine uptake: evidence from a joint analysis in rural Senegal.
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
backgroundCurrent malaria vaccination efforts target infants from 5 months of age; however, adult malaria mortality remains a significant and under-reported issue in high-transmission settings. Concerns are emerging that COVID-19-related vaccine hesitancy may extend to upcoming vaccines, including hypothetical ones such as a malaria vaccine for adults. This study investigates both shared and vaccine-specific determinants of malaria vaccination intention, comparing them with those influencing COVID-19 vaccine uptake.
methodsA cross-sectional telephone survey was conducted in 2023 among 795 adults residing in the rural area of Niakhar, Senegal. The Health Belief Model served as the analytical framework to identify determinants of vaccination behaviours and intentions. A multivariable bivariate probit model was used to jointly assess factors associated with favourable intentions to receive a hypothetical adult malaria vaccine and actual uptake of the COVID-19 vaccine.
resultsAmong surveyed participants, 35.6% had received at least one dose of a COVID-19 vaccine, and 58.6% expressed favourable intentions to receive a malaria vaccine, assuming it were available and free of charge. COVID-19-vaccinated individuals were 60% (p < 0.001) more likely to report favourable intentions to receive a malaria vaccine. In the multivariable probit model, perceived disease severity was more strongly associated with COVID-19 vaccine uptake, whereas perceived disease susceptibility more strongly predicted favourable intentions to receive a malaria vaccine. Women were more likely to support malaria vaccination (p = 0.005), while adults aged 59 years and older had higher rates of COVID-19 vaccination (p < 0.001).
conclusionsThese findings suggest that although some determinants are vaccine-specific, most are shared across vaccines. The results offer actionable insights to guide future malaria vaccination strategies. Further research in urban settings and across diverse countries is warranted to enhance understanding of cross-vaccine perceptions and to inform targeted communication efforts.
