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

The first approval of malaria vaccines RTS,S/AS01 and R21/Matrix M marked a major milestone. Both vaccines present a portion of the Plasmodium falciparum circumsporozoite protein (PfCSP) containing an immunodominant major repeat region, which may limit breadth to other protective epitopes, limiting efficacy and durability. Using B cell receptor (BCR) knock-in mice, we found that the R21-included PfCSP epitope elicited robust B cell responses to the immunodominant major repeats but not to other highly protective epitopes, the minor repeat and junction. We then defined a minimal peptide capable of eliciting minor repeat-specific B cell responses and generating highly protective antibodies (Abs). We characterized these Abs bioinformatically and structurally to identify protective traits, which informed the design of variant Abs with improved affinity. Finally, we demonstrated that vaccination combining the R21-included PfCSP epitope, the minimal minor repeat peptide, and a junctional region immunogen elicited balanced B cell and Ab responses, enhancing protection in vivo. Broadening responses through immunofocusing may overcome immunogenic gaps in current malaria vaccines.
