The impact of risk prioritization in COVID-19 vaccination in Belgium on hospital and intensive care unit admissions.
Article in European journal of 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
Belgium prioritized primary COVID-19 vaccination of persons aged 18-64 years with underlying health conditions over their same-aged peers, leading to an accelerated administration of a first dose of 35 days. We assessed this strategy's impact on hospital admissions, in comparison to alternative scenarios, using generalized causal inference techniques with a hierarchical Bayesian model. A solely age-based scenario showed a significant increase in hospital admissions of 254, while random-allocation and no-vaccination scenarios showed even higher increases (604 and 1998, respectively). These results emphasize the importance of prioritization strategies in a pandemic context and the benefits of COVID-19 vaccines in general.
