Building Vaccine Readiness for Future Pandemics: Insights from COVID-19 Vaccine Intent and Uptake.
Article in Vaccines, 2025. 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
BACKGROUND/
objectivesThis longitudinal study investigated psychosocial predictors of COVID-19 vaccine intentions before vaccine availability (July 2020) and vaccine uptake or ongoing intent after widespread vaccine rollout (April 2021) using constructs from the Health Belief Model (HBM) and a measure of trust in government.
methodsA U.S. adult sample (N = 142) completed surveys at two time points: prior to and following the release of COVID-19 vaccines. Key predictors included demographics, trust in government, and HBM constructs. Hierarchical logistic regression was used to predict vaccine intent and uptake at both time points.
resultsAt Time 1, intent to vaccinate was significantly predicted by higher perceived susceptibility (
conclusionsPerceived benefits and barriers were robust predictors of vaccine behavior across both time points. Trust in government became a stronger predictor once vaccines were available, underscoring the importance of building and maintaining public trust throughout a health crisis. Messaging should emphasize vaccine benefits, proactively address barriers, and adapt over time as public perceptions shift. These findings inform strategies for enhancing vaccine confidence and readiness in future pandemics.
