Incorporating public values into public health communications: Effects of value affirmations on intentions to vaccinate and trust in the U.S.
Article in PloS one, 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
A set of COVID-19 pro-vaccine messages that aligned with key social values of vaccine-hesitant individuals was developed. In Spring of 2021, unvaccinated adults in the U.S. (n = 1,170) completed an online survey in which they were randomly assigned to read through one of several different pro-vaccine messages, followed by assessments of their future COVID-19 vaccine likelihood and level of trust in government, health care, and vaccines. Relative to a control condition, messages that affirmed individuals' distrust in the government and concerns over restrictions on personal liberty resulted in higher vaccination likelihood and greater trust. While the observed effect sizes of these messaging conditions were small, the findings have implications for broadening the value frames of public health appeals and understanding how and why vaccine hesitancy acts as a powerful way for people to express their values and authentic experiences.
