Human vaccine responses regulated by parallel cytokine pathways.
Article in Nature immunology, 2026. 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
Human vaccine responses vary widely, but the determinants remain incompletely defined. Here we analyzed 66 cytokines across four inactivated influenza vaccine (IIV) cohorts over five seasons (n = 581) and identified baseline serum interleukin (IL)-18 and interferon (IFN)-β as correlates of day 28 antibody responses. To test causality, we evaluated 19 cytokines in human tonsil and spleen organoids and found that type I IFNs, IL-21 and IL-12, but not IL-18 or IFNγ, enhanced antibody production. The addition of IFNβ to IIV recapitulated key features of the live-vaccine cytokine program. IL-12 and IL-21 defined a parallel pathway independent of type I IFNs, with IL-12 inducing IL-21 in humans, unlike in mice. Delivery of IL-21 or IFNβ via mRNA lipid nanoparticles in vivo promoted long-lived plasma cell formation. Together, these findings define parallel pathways that regulate vaccine immunity. Our approach unites high-throughput organoid testing and human cohort studies, establishing a human-centric platform to identify adjuvant candidates.
