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

mRNA vaccines represent a promising alternative to conventional vaccines, as demonstrated by the rapid deployment of mRNA vaccines during the recent COVID-19 pandemic. In this work, we have adapted and fine-tuned various reported mRNA lipid nanoparticle (LNP) synthesis and preparation procedures, evaluated a range of ionizable cationic lipids, and identified top-performing LNP formulations. The impact of uridine modification on mRNA's ability to trigger immune responses has also been explored. Our findings indicate that both unmodified mRNA and N1-methyl pseudouridine-modified mRNA successfully induced an antigen-specific antibody response in mice, while the methoxy uridine-modified mRNA did not. Based on these studies, we constructed a bivalent Fluvid mRNA vaccine, consisting of LNPs encapsulating uridine-unmodified mRNA encoding either a transmembrane domain-deleted hemagglutinin or the full-length native spike protein. This vaccine stimulated robust T cell and B cell immune responses and conferred 100% protective efficacy against challenge with either influenza or SARS-CoV-2 viruses in the mouse model, without compromising efficacy compared to administering each monovalent vaccine individually. Our data suggest that the multivalent mRNA vaccine can offer protection against different viruses by generating humoral and cellular responses against multiple antigens at the same time.
