mRNA-delivered neutralizing antibodies confer protection against SARS-CoV-2 in animal models.
Article in Journal of virology, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
Monoclonal antibodies represent potent biological countermeasures against a wide range of human diseases; however, their clinical application and widespread use are limited by the high cost and complexity of antibody production and manufacturing. The mRNA-lipid nanoparticle (mRNA-LNP) platform offers a versatile strategy for vaccine development and protein-replacement therapies. Since the COVID-19 pandemic, a number of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2)-neutralizing antibodies have been identified, with several granted emergency use authorization for patients. Here, we report the design and generation of mRNA-LNPs encoding two SARS-CoV-2-neutralizing antibodies, 76E1 and LY1404, which, respectively, target the spike protein's fusion peptide (FP) and receptor-binding domain (RBD). We demonstrated that a single intramuscular administration of these mRNA-LNPs in mice resulted in robust antibody production that sustained in circulation for 7-14 days. Furthermore, we evaluated protective effects of these mRNA-delivered antibodies in animal models and showed that a single IM dose of mRNA-LNPs encoding LY1404 or 76E1 conferred significant protection against multiple SARS-CoV-2 variants, including Omicron BQ.1 and Delta, in mice and hamsters. Collectively, these findings highlight the potential of mRNA-based antibody delivery for rapid prevention or treatment of pathogenic infections.IMPORTANCENeutralizing antibodies represent potent biological countermeasures against viral infections.

A single intramuscular administration of mRNA-LNPs encoding LY1404 or 76E1 resulted in rapid antibody production in circulation and conferred protection against multiple strains of SARS-CoV-2 infection in animal models. Our findings highlight the potential of mRNA-based antibody delivery for rapid prevention or treatment of pathogenic infections.
