Immunoinformatics-Based Multi-Epitope Vaccine Targeting Helicobacter Pylori.
Article in Cancer reports (Hoboken, N.J.), 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
backgroundThe rising global incidence of Helicobacter pylori-related diseases, particularly gastric cancer, underscores the urgent need for effective preventive vaccines, motivating the exploration of innovative immunoinformatic strategies to address this public health challenge.
aimsThe aim of this study was to design a multi-epitope subunit vaccine for Helicobacter pylori using an immunoinformatics approach. Specifically, the objectives were to predict potential epitopes from the flagellin B and urease B proteins, integrate the cholera toxin B subunit (CTB) as a mucosal adjuvant, and perform computational validation of the vaccine construct for antigenicity, stability, and interaction with immune receptors.
methodsThis study utilized an immunoinformatics approach to design a multi-epitope subunit vaccine, involving epitope prediction from flagellin B and urease B, integration of the cholera toxin B subunit (CTB) as a mucosal adjuvant, and computational validation through tools like VaxiJen, Phyre2, MolProbity, and HDOCK for antigenicity, structure, and docking analysis.
resultsThe resulting vaccine construct comprises 406 amino acids with a molecular weight of 43 424.77 Da, exhibiting a predicted antigenic score of 1.0084, non-allergenic and non-toxic properties, and a stable physiochemical profile (instability index 23.51, GRAVY -0.425). Structural analysis suggested 99.1% (525/530) of residues in favored Ramachandran regions and 100.0% in allowed regions. Molecular docking with Toll-like receptor 5 (TLR5) indicated a superior docking score of -309.05 and a confidence score of 0.9601, outperforming TLR2 (-250.74), with 10 CTL epitopes (6 from flagellin B, 4 from urease B), 6 HTL epitopes, and 2 LBL epitopes linked by AAY, GPGPG, and KK linkers, respectively.
conclusionThis research provides a computationally optimized vaccine design that shows potential for eliciting immune responses against H. pylori. Importantly, the findings remain entirely theoretical and require rigorous experimental validation in vitro and in vivo to assess their immunological relevance, safety, and efficacy before any translational or clinical application can be considered.
