Post-coronavirus disease 2019-associated symptoms among children and adolescents in the SARS-CoV-2 Omicron era.

Purpose: Lack of a control group(s) and selection bias were the main criticisms of previous studies investigating the prevalence of post-coronavirus disease 2019 (COVID-19) syndrome (PCS). There are insufficient data regarding paediatric PCS, particularly in the SARS-CoV-2 Omicron era. As such, our study investigated PCS-associated symptoms in a representative control-matched cohort.

PaedVacCOVID - safety of the BNT162b2 vaccine against the SARS-CoV-2 in children with and without comorbidities aged 5 to 11 years.

This study's purpose is to evaluate safety and adverse events in these children compared to healthy children.

Methods: In this prospective, multicentre, industry-independent cohort study, caregivers whose children received BNT162b2 were asked to participate in an online questionnaire.

Post-COVID-19-pandemic changes and clinical characteristics of invasive group a streptococcal infections from 2015 to 2023.

Purpose: Since winter 2022, invasive GAS (iGAS) infections have re-emerged in Europe, causing severe diseases in children and adults. We aimed to examine whether this reported post-pandemic increase was associated with an increased disease severity and/or a shift in clinical disease phenotypes.

Methods: We performed detailed clinical phenotyping of patients hospitalized with iGAS infections at a 1410-bed tertiary German Medical Center from 01/2015 to 09/2023.
