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

Replication-defective vaccine vectors based on vesicular stomatitis virus (VSV) lacking its envelope glycoprotein gene (G) are highly effective in animal models. However, such ΔG vectors are difficult to grow because they require complementation with the VSV G protein. In addition, the complementing G protein induces neutralizing antibodies in animals and thus limits multiple vector applications. In the process of generating an experimental Nipah virus (a paramyxovirus) vaccine, we generated two defective VSVΔG vectors, each expressing one of the two Nipah virus (NiV) glycoproteins (G and F) that are both required for virus entry to host cells. These replication-defective VSV vectors were effective at generating NiV neutralizing antibody in mice. Most interestingly, we found that these two defective viruses could be grown together and passaged in tissue culture cells in the absence of VSV G complementation. This mixture of complementing defective viruses was also highly effective at generating NiV neutralizing antibody in animals. This novel approach to growing and producing a vaccine from two defective viruses could be generally applicable to vaccine production for other paramyxoviruses or for other viruses where the expression of at least two different proteins is required for viral entry. Such an approach minimizes biosafety concerns that could apply to single, replication-competent VSV recombinants expressing all proteins required for infection.
