Immunological and structural evaluation of the intranasally administrated CVB1 whole-virus and VLP vaccines.
Article in Scientific reports, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 papers.
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
Coxsackievirus B1 (CVB1) is a common cause of acute and chronic myocarditis, cardiomyopathy, and meningitis. CVBs replicate in mucosal membranes. Therefore, vaccines inducing robust mucosal immune responses are needed. We investigated the immunogenicity of virus-like particles (VLP) and inactivated virus vaccines for CVB1, administered to mice either subcutaneously or intranasally, formulated with and without commercial and an experimental adjuvant. In this study, epigallocatechin-3-gallate (EGCG) was used both as a potential adjuvant and as an inactivating agent. EGCG adjuvanted CVB1-VLP enhanced immunogenicity via the parenteral route, but not intranasally. EGCG-adjuvanted and non-adjuvanted CVB1-VLPs triggered an immune response after intranasal administration, although the response remained weak. Intranasal administration of formalin-inactivated virus elicited robust CVB1-specific humoral, cellular, and mucosal immune responses, but after EGCG-inactivation, the mucosal antibody response was lower than after formalin-inactivation. To identify the link between structure and mucosal immunogenicity, we solved the structures of CVB1-VLP and formalin-inactivated CVB1 virus at resolutions ranging from 2.15 to 4.1 Å. The structural difference between VLP and formalin-inactivated CVB1 was the presence of the genome and cross-linked amino acid residues in the formalin-inactivated virus. Formalin-inactivated CVB1 vaccine shows promise for mucosal immunizations and the structural data supports the development of next-generation VLP-vaccines in the future.
