Development of SARS-CoV-2 as a viral vector: A novel intranasal bivalent vaccine for SARS-CoV-2 and RSV.
Article in Science advances, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 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
Negative-sense RNA viruses have been widely used as viral vectors for vaccine delivery. However, little is known about coronaviruses as vectors for delivering vaccines. Here, we have developed safe SARS-CoV-2 Omicron JN.1-based live attenuated vaccine candidates by combining a mutation (D130A) in the viral nsp16 protein, deletion of the furin cleavage site (dFCS) in the spike protein, deletion of accessory proteins, and/or modification of the transcription regulatory sequences (mTRS). Subsequently, using rJN.1, rJN.1-D130A-dFCS, and rJN.1-mTRS-D130A-dFCS as the backbones, we generated three recombinant viruses expressing a nonfunctional, soluble, and stabilized prefusion F protein of human respiratory syncytial virus (RSVF). Among them, rJN.1-D130A-dFCS-RSVF virus was sufficiently attenuated and highly immunogenic, providing complete protection against challenge with both JN.1 and RSV in hamsters. However, rJN.1-mTRS-D130A-dFCS-RSVF was poorly immunogenic. Collectively, we demonstrate that attenuated SARS-CoV-2 is an effective viral vector for delivering RSV vaccine, warranting further development as a novel intranasal bivalent vaccine for SARS-CoV-2 and RSV.
