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

BACKGROUND/

objectivesThe antibody-dependent enhancement (ADE) of viral entry has been documented for SARS-CoV-2 infection both in vitro and in vivo. However, the potential for the SARS-CoV-2 vaccination to elicit similar ADE effects remains unclear.

methodsIn this study, we assessed the in vitro ADE potential of monoclonal antibodies (mAbs) derived from individuals vaccinated with the inactivated SARS-CoV-2 vaccine and compared them to those from one convalescent donor.

resultsOur analysis revealed no significant difference in binding affinity or neutralizing capacity between the vaccinated and convalescent mAbs. However, the inactivated SARS-CoV-2 vaccination induced fewer ADE-inducing mAbs, particularly those targeting the Class III epitope on the receptor-binding domain (RBD) compared to those from the convalescent individual. Moreover, no significant in vitro ADE was detected in either vaccinated or convalescent sera, indicating low levels of ADE-inducing antibodies in the sera.

conclusionsAn inactivated SARS-CoV-2 vaccination induces fewer ADE-inducing antibodies compared to natural infection, further emphasizing the safety of inactivated SARS-CoV-2 vaccines.
