Pre-vaccine immune profiling in cancer patients identifies correlates of COVID-19 vaccine responses.
Article in Human vaccines & immunotherapeutics, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
mRNA vaccines have been highly effective against SARS-CoV-2-related severe illness and are currently undergoing investigation as anti-cancer therapeutics. Our prior work has shown that patients undergoing cancer therapy have reduced immune responses to mRNA-based vaccines. Therefore, further investigation into immunologic responses in the setting of immune-altered hosts is warranted. In this study, we investigated pre-vaccination peripheral immune cell repertoire from a cohort of 66 patients with cancer on active treatment. Immune cell repertoire was characterized by mass cytometry to identify key immune subsets for COVID-19 vaccine response. Immunological populations were then assessed for their association with spike-specific antibody titers measured by ELISA and the breadth and depth of T-cell response to vaccine by TCR sequencing. Immune features significantly correlated with response were selected using an iterative bootstrapping model. We identified immunological features including abundance and functional state of T and B cells, expression of co-stimulatory and -inhibitory molecules, and presence of innate lymphoid cells, and myeloid-derived suppressor cells correlated with humoral and cellular responses. Our findings suggest that vaccine-induced immune responses could serve as biomarkers of immune fitness, in general and specifically for patients receiving anti-cancer mRNA vaccines, providing insights to tailor future therapeutic strategies for immune-altered patients.
