The association between depressive symptoms and antibody response following SARS-CoV-2 vaccination among central North Carolina residents.
Article in PLOS mental health, 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
A large body of research suggests that stress can affect how the immune system responds to vaccines. The impact of mental health disorders on humoral antibody response following immunization is not well understood, particularly for the COVID-19 vaccines. Leveraging a population-based longitudinal cohort assessing SARS-CoV-2 incidence in central North Carolina, we sought to investigate the relationship between mental health and immune response to vaccination. The 106 participants responded to biweekly surveys and contributed monthly serum samples that underwent SARS-CoV-2 spike antibody testing via enzyme-linked immunosorbent assay (ELISA). Utilizing weighted generalized linear models, we measured the association between depressive symptoms as recorded on the CESD-20 and quantitative antibody levels after COVID-19. Overall, we found modest differences in post-vaccination IgG between participants with depression and those without. Individuals with depressive symptoms had smaller initial antibody responses after vaccination (mean difference = -3.55, 95% CI = (-12.01, 4.90)). These results suggest that mental health disorders may affect immune response to vaccination.
