Persistence of memory: lifespan dynamics of the human antiviral antibody reactome.
Article in Nature communications, 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
The human antiviral antibody reactome provides a cumulative molecular record of immune exposures. Using high-resolution VirScan profiling, we compared epitope-level antibody responses across early childhood and adulthood. Infants are born with maternal IgG antibodies, but these antibodies decay rapidly and are replaced by endogenous responses to ~22 new viral exposures within three years. Pediatric antibody reactivities remain highly dynamic until about age 7 and are broad in epitope specificity but largely short-lived. In contrast, adult reactomes are remarkably stable and individualized, enabling accurate longitudinal donor identification (Immunoprint, > 99.99% accuracy). Stability varies by viral family, with Pneumoviridae and Picornaviridae persisting more robustly than Coronaviridae or Orthomyxoviridae. Across ages, immunodominant epitopes and initial binding strength predict response persistence. Longitudinal profiling highlights biological and epidemiological drivers of reactome change. This population-level, age-stratified atlas informs our understanding of immune memory and development with applications to vaccine design, surveillance, and precision public health.
