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

There are currently no licensed therapeutic treatment or preventive vaccines against Ebolavirus disease, and the 2013-2016 West African outbreak of Ebolavirus disease spread rapidly and resulted in almost 30,000 cases and more than 11,000 deaths. However, the devastating outbreak has spurred the development of novel Ebolavirus vaccines. Here, we demonstrate that alphavirus-based DNA-launched self-replicating RNA replicon vaccines (DREP) encoding either the glycoprotein (GP) gene or co-expressing the GP and VP40 genes of Sudan or Zaire Ebolavirus are immunogenic in mice inducing both binding and neutralizing antibodies as well as CD8 T cell responses. In addition, antibodies were cross-reactive against another Ebolavirus, although the specificity was higher for the vaccination antigen. DREP vaccines were more immunogenic than recombinant MVA vaccines expressing the same Ebolavirus antigens. However, a DREP prime followed by an MVA boost immunization regimen improved vaccine immunogenicity as compared to DREP and MVA homologous prime-boost immunizations. Moreover, we show that a bivalent approach targeting both Sudan and Zaire Ebolavirus can be employed without significant loss of immunity. This opens for further investigation of a pan-Ebolavirus or even a pan-filovirus vaccine.
