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 extraordinary success of vaccines saving lives and improving human health is predicated on immune memory. Within the armamentarium of adaptive immunity, a holistic view of the different components contributing to immune protection is important for understanding the myriad benefits of vaccines. This review presents the current understanding of vaccine-generated memory, integrating layers of immunity including B cells, CD8+ T cells, CD4+ T cells, and antibody responses, with emphasis on human vaccine data. Functions and durability of distinct memory types are considered, including those of tissue-resident and circulating cells as well as hybrid immunity, and within this context, common misconceptions and important next questions are discussed. Understanding the multifaceted layers that underlie protective immunity can guide future vaccines and broader immune-focused interventions. A video lecture accompanies this review (https://youtu.be/8DeZJ6V7nuI). VIDEO ABSTRACT.
