Targeting heptad repeats and fusion peptide: nanoparticle vaccine elicits mucosal immune response against SARS-CoV-2 variants.
Article in Journal of nanobiotechnology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 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
The emergence of SARS-CoV-2 variants has underscored the urgent need for innovative vaccine strategies that provide robust and enduring protection against diverse strains. Our study introduces the FP-HR5 nanoparticle vaccine, designed to target the highly conserved S2 subunit of the spike protein, including the fusion peptide (FP) and heptad repeats (HR1 and HR2), using a 24-mer Helicobacter pylori ferritin platform. Administered intranasally, the FP-HR5-NP vaccine elicits robust systemic and mucosal immune responses in vivo, generating high titers of FP- and HR5-specific IgG antibodies. Notably, intranasal immunization resulted in elevated levels of secretory IgA and IgG in bronchoalveolar lavage fluid (BALF) and stimulated T-cell immune responses, significantly increasing resident memory B cells (B
