Prick tests and basophil activation tests in hypersensitivity to SARS-CoV-2 vaccines and components.
Article in Allergologie select, 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
In collaboration with certified allergy centers (CACs) in Germany, a standardized procedure was developed for the allergologic evaluation of hypersensitivity reactions to SARS-CoV-2 vaccines. Our CAC prospectively evaluated 60 subjects with prior allergic reactions to SARS-CoV-2 vaccines or components. The investigations included a comprehensive medical history, in-vitro and skin tests. Prick tests were negative in all participants. Two positive basophil activation tests suggested a hypersensitivity to the component polyethylene glycol; however, no clinical relevance was found. Approximately 73% of the subjects reported symptoms during subsequent immunizations, which were milder than the reactions prior to the diagnostic procedures. Most index reactions manifested as non-specific symptoms. The results suggest that subsequent vaccinations following diagnostic procedures were well tolerated, underscoring the importance of careful allergological evaluation prior to vaccination.
