Occurrence of adverse events following vaccination in patients with allergies: a prospective study.
Article in Central European journal of public health, 2024. 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
objectivesAllergic patients may be concerned about more frequent and/or more severe adverse events following vaccination, which may lead to the refusal of vaccines among these patients. The aim of this study is to assess whether allergic patients have more frequent adverse events (AEs) after vaccination than healthy individuals.
methodsStudy participants (N = 591) underwent vaccination of their choice at a selected Vaccination and Travel Medicine Centre. At a 10 to 14-day interval, they were contacted for a telephone questionnaire survey on the occurrence of AEs after vaccination. A group of allergic patients (n = 188) and healthy controls (n = 403) were followed in the study.
resultsNo significant difference was found in the occurrence of AEs between study and control group. Only in redness and swelling, which was more common in allergic patients, but only in a few individuals. All side effects were minor, such as pain at the injection site or fatigue. No participant experienced a serious or life-threatening adverse event. In the studied group, no statistically significant differences were found even in the occurrence of AEs after singular vs. simultaneous administration of vaccines (p = 0.094), nor after vaccination with inactivated vs. attenuated vaccines (p = 0.655), or after vaccination against bacterial vs. viral infections (p = 0.140).
conclusionsVaccination of allergic patients did not cause more frequent and/or more serious adverse events in our study compared to healthy people. If general contraindications are observed, then vaccination of allergic patients is considered safe.
