Ad26.RSV.preF completely protects calves from severe respiratory disease induced by bovine RSV challenge.

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
Vaccination with Ad26.RSV.preF, an Adenoviral serotype 26 vector encoding RSV F protein stabilized in its prefusion conformation, has previously shown to be immunogenic and protective in RSV seropositive adults and immunogenic in seropositive infants. Human and bovine RSV (bRSV) are genetically highly related and share many aspects of pathogenesis, epidemiology and clinical manifestations at young age. As such, infection of calves with bRSV represents a clinically relevant model with high translational value, enabling preclinical evaluation of Ad26.RSV.preF vaccine efficacy in seronegative young animals. Immunization of young calves with Ad26.RSV.preF induced antibodies neutralizing both human and bovine RSV as well as RSV-specific cellular responses. After bRSV challenge, placebo immunized calves showed viral replication in the respiratory tract, and developed fever and lethargy accompanied with severe respiratory distress, resulting in pre-termination of 7/8 calves. In contrast, all Ad26.RSV.preF immunized calves completed the study with only mild clinical symptoms, strongly and significantly diminished viral loads in nasopharynx and lungs, and only minimal lung pathology. Thus, Ad26.RSV.preF is immunogenic in young calves and efficacious in a stringent heterologous bRSV challenge model, demonstrating induction of broadly protective immunity against severe disease.
