Examining the association of vaccine-related mindsets and post-vaccination antibody response, side effects, and affective outcomes.
Article in Brain, behavior, & immunity - health, 2024. 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: Although vaccines are largely effective and safe, there is variability in post-vaccination experience regarding antibody response, side effects, and affective outcomes. Vaccine mindsets, specific beliefs about the vaccine, may be associated with post-vaccination experience. This is important since mindsets are malleable and may help decrease vaccine hesitancy and improve post-vaccination experience. Methods: In a prospective study, we measured overall positive vaccine mindset and specific mindsets regarding efficacy, body response, and side effects. We tested whether vaccine mindsets before vaccination predicted neutralizing antibody response, side effects, vaccine-related stress, and affective outcomes (general stress, sadness, and happiness). Antibody response was assessed one month and six months after participants completed a SARS-CoV-2 vaccination series. Side effect experience and affective reactions were assessed daily on the vaccination day and the subsequent five days. Results: There was no significant association between the aggregate vaccine mindset score and neutralizing antibody response; however, people with a more positive vaccine mindset reported fewer side effects, less same-day vaccine-related anxiety, and improved affective outcomes after vaccination. In secondary analyses, when specific mindsets were explored, the mindset that vaccine side effects are a sign of treatment efficacy predicted higher antibodies, but not side effects experience and vaccine-related anxiety. Vaccine efficacy and body-response mindsets predicted fewer side effects, vaccine-related anxiety, and improved affective outcomes after vaccination. Conclusion: These findings underscore the potential of vaccine mindsets in enhancing the overall post-vaccination experience and, in some cases, increasing antibody response.
