Impact and Effectiveness of <span>COVID</span> ‐19 <span>mRNA</span> Vaccination Against <span>COVID</span> ‐19 Hospitalisation in Paediatrics: A Cohort Study Using Two Linked Data Sources in Spain Open
Purpose Despite Spain's > 2 million COVID‐19 paediatric cases before 2024, few required hospitalisations (8900). We aimed to estimate the effectiveness of two‐dose COVID‐19 vaccinations against hospitalisation ‘with’ and ‘for’ COVID‐19 in …

Applying two approaches to detect unmeasured confounding due to time-varying variables in a self-controlled risk interval design evaluating COVID-19 vaccine safety signals, using myocarditis as a case example Open
We test the robustness of the self-controlled risk interval (SCRI) design in a setting where time between doses may introduce time-varying confounding, using both negative control outcomes (NCOs) and quantitative bias analysis (QBA). All v…

A comparison of four self-controlled study designs in an analysis of COVID-19 vaccines and myocarditis using five European databases Open
In the context of the known association between COVID-19 vaccines and myocarditis, we have demonstrated that two forms of SCRI and two forms of SCCS led to largely comparable results, possibly because of limited violation of the assumption…

A comparison of four self-controlled study designs in an analysis of COVID-19 vaccines and Myocarditis using Five European Databases Open
Introduction The aim of this study was to assess the possible extent of bias due to violation of a core assumption (event-dependent exposures) when using self-controlled designs to analyse the association between COVID-19 vaccines and myoc…
