DS2 designer pre-fusion F vaccine induces strong and protective antibody response against RSV infection.
Article in NPJ vaccines, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 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
DS-Cav1, SC-TM, and DS2 are distinct designer pre-fusion F proteins (pre-F) of respiratory syncytial virus (RSV) developed for vaccines. However, their immunogenicity has not been directly compared. In this study, we generated three recombinant vaccines using the chimpanzee adenovirus vector AdC68 to express DS-Cav1, SC-TM, and DS2. All three vaccines elicited robust serum binding and neutralizing antibodies following intramuscular priming and boosting. DS2 induced the strongest antibody responses, followed by SC-TM and DS-Cav1. DS2 also provided strong protection against live RSV challenge. Monoclonal antibodies (mAbs) isolated from long-lived antibody-secreting cells (ASCs) in the bone marrow six months post-immunization with AdC68-DS2 predominantly targeted site Ø as well as site II. One neutralizing antibody against site II, mAb60, conferred strong protection against live RSV infection in mice. These findings highlight the strong ability of the DS2 design in eliciting long-lived antibody responses and guide the development of next-generation RSV vaccines.
