mRNA vaccines encoding variant forms of Sm-TSP-2 confer protective immunity against Schistosoma mansoni.
Article in NPJ vaccines, 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
This study explored the development and evaluation of mRNA vaccine candidates targeting Schistosoma mansoni tetraspanin-2 (Sm-TSP-2). We designed constructs encoding either full-length Sm-TSP-2, or its large extracellular loop (EC2) domain in secretory, membrane-anchored, or cytosolic forms. In a murine model, the secreted and membrane-anchored versions of Sm-TSP-2-EC2 induced the highest antigen-specific antibody titers. These two construct designs, along with full-length Sm-TSP-2 mRNA, also significantly reduced adult worm and egg burden compared to controls. The membrane-anchored Sm-TSP-2-EC2 mRNA was the most effective, lowering worm and egg burdens by 66.7% and 66.9%, respectively. Protective responses induced by the mRNA vaccines were comparable to those elicited by the Sm-TSP-2-EC2 protein formulated with Alum. Histopathological analysis revealed smaller hepatic granulomas surrounding worm eggs, supporting the immunopathological benefit of vaccination. Using a systematic mRNA-based approach, we optimized the presentation of the Sm-TSP-2-EC2 and demonstrated that extracellular exposure of EC2 is essential for eliciting a protective response.
