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

Self-amplifying mRNA vaccines use a viral replicase for self-amplification. It is currently unclear whether anti-replicase immunity occurs after saRNA vaccination, and whether such pre-existing anti-replicase immunity impacts the efficacy of subsequent saRNA vaccines. Using female mice, this study demonstrates that an initial saRNA vaccination schedule elicits replicase-specific immunity, which reduces the in vivo expression and impairs the Th1 cell responses of subsequent saRNA vaccines. Passive transfer experiments demonstrate that the suppression of T cell responses is driven by a synergistic effect of both anti-replicase antibodies and anti-replicase T cells. Interestingly, pre-existing anti-replicase immunity does not affect the ability of an influenza saRNA vaccine to provide full protection against an H5N1 challenge in female mice. Taken together, these results provide crucial insights on the effects of anti-replicase immunity induced by a first saRNA vaccination schedule on the expression, immunogenicity and protection efficacy of a subsequent saRNA vaccine.
