1 · What the graph read from it

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.

2 · The registry

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

Respiratory syncytial virus (RSV) causes severe respiratory disease in infants and the elderly. However, natural infection fails to induce durable immune protection, and existing mRNA vaccines for older adults exhibit limited long-term efficacy. We developed an antigen engineering strategy inserting ESCRT/ALIX-binding region (EABR) into truncated RSV prefusion F (PreF) cytoplasmic tails to form enveloped virus-like particles (eVLPs). In murine models, PreF-EABR mRNA vaccines elicited higher, more persistent neutralizing antibodies than conventional PreF mRNA, correlating with enhanced germinal center B cell and memory B cell responses. A lower dose of PreF-EABR mRNA (1 μg) suppressed viral load and pathology comparable to higher-dose PreF mRNA (2.5 μg). Transcriptomic analysis showed PreF-EABR mRNA activated toll-like receptor and chemokine signaling pathways, enhancing antibody longevity via platelet-associated signatures. This study explores the development and possible mechanism of long-lasting RSV mRNA vaccines by eVLPs technology, which also suggest its potential application in other vaccines.
