COVID-19 vaccination induces cross-neutralisation of sarbecoviruses related to SARS-CoV-2.
Article in NPJ vaccines, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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.
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 combined threats of future sarbecovirus zoonosis and continually emerging SARS-CoV-2 VOCs highlight the need to assess the breadth of existing SARS-CoV-2 vaccine-mediated protection. Here, we investigate a cohort of older individuals who received four COVID-19 vaccine doses, for potential cross-neutralisation against lentiviral particles bearing spikes from either Omicron VOCs or other sarbecoviruses. Despite recent fourth bivalent mRNA vaccine doses (encoding SARS-CoV-2 Wu-1 and Omicron spikes), neutralisation of Omicron lineage VOCs was reduced compared to Wu-1, consistent with an imprinted immune response. Similarly, particles bearing either SARS-CoV-1 or a SARS-CoV-1-related bat sarbecovirus spike were neutralised less efficiently than Wu-1. Unexpectedly, however, we observed that particles with spikes from two animal SARS-CoV-2-related viruses, BANAL-20-52 from bats and a pangolin CoV, were significantly more sensitive to serum neutralising antibodies than SARS-CoV-2 Wu-1 itself. These surprising findings suggest that vaccine-mediated adaptive immunity may provide efficient cross-neutralisation and potential protection against certain animal sarbecoviruses.
