PaedVacCOVID - safety of the BNT162b2 vaccine against the SARS-CoV-2 in children with and without comorbidities aged 5 to 11 years.
Article in Infection, 2025. 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
backgroundLittle is known about specific safety aspects in children with significant comorbidities receiving the mRNA vaccine BNT162b2, as approval studies did not address this population. This study's purpose is to evaluate safety and adverse events in these children compared to healthy children.
methodsIn this prospective, multicentre, industry-independent cohort study, caregivers whose children received BNT162b2 were asked to participate in an online questionnaire. Potential side effects were evaluated in ten organ related categories. Frequency of symptoms was compared in both cohorts by bivariate analysis.
resultsFrom a total of 1,294 responses to the questionnaire, 793 data sets were included into the analysis (179 children with comorbidities and 614 healthy children). Responses were given at a median of 17 days after vaccination. Overall, safety of BNT162b2 was high in both cohorts. Psychological (OR: 3.56, [95% CI: 1.461 to 8.629]), pulmonary (OR: 7.14, [95% CI: 2.039 to 21.48]), gastrointestinal (OR: 2.35, [95% CI: 1.231 to 4.665]), neurological (OR: 1.74, [95% CI: 1.078 to 2.796]) and dermatological (OR: 2.28, [95% CI: 1.220 to 4.172]) side effects were increased in children with comorbidities over healthy controls.
conclusionThe higher rate of reported post-vaccination symptoms could either be due to a higher susceptibility for symptomatic effects following immune stimulation, or due to a trained awareness to health-related symptoms. The data emphasizes the importance to evaluate safety of the new mRNA COVID-19 vaccines not only in healthy children but also in children with comorbidities. To perform such evaluation should be made mandatory for pharmaceutical enterprises.
