Abstract Purpose Despite the need to generate valid and reliable estimates of protection levels against SARS-CoV-2 infection severe course COVID-19 for German population in summer 2022, there was a lack systematically collected population-based data allowing assessment level real time. Methods In IMMUNEBRIDGE project, we harmonised biosamples nine population-/hospital-based studies (total number participants n = 33,637) provide between June November 2022. Based on evidence synthesis, formed...

IntroductionThroughout the SARS-CoV-2 pandemic, Germany like other countries lacked adaptive population-based panels to monitor spread of epidemic diseases.MethodsTo fill a gap estimates needed for winter 2022/23 we resampled in German cohort study MuSPAD mid-2022, including characterization systemic cellular and humoral immune responses by interferon-γ-release assay (IGRA) CLIA/IVN assay. We were able confirm categorization our population into four groups with differing protection levels...

Abstract Throughout the SARS-CoV-2 pandemic, Germany lacked an adaptive population panel for epidemic diseases and a modelling platform to rapidly incorporate estimates. We evaluated how cross-sectional analysis of 9922 participants MuSPAD study in June/July 2022 combined with newly developed could bridge gap analyzed antibody levels, neutralizing serum activity interferon-gamma release response samples. categorized into four groups differing protection against severe course disease...
