COVID-19 vaccine responses are influenced by distinct risk factors in naive and SARS-CoV-2 experienced hemodialysis recipients
experienced HDR. These observations have important implications for the understanding of vaccine-induced immunity and for the management of this vulnerable patient population. Health Topics: SARS-CoV-2 ...
Federated causal inference based on real-world observational data sources: application to a SARS-CoV-2 vaccine effectiveness assessment.
interventions or public health programs by leveraging observational sensitive individual-level data from populations crossing jurisdictional borders, a federated approach (as opposed to a pooling data approach) ...
Evaluating methodological approaches to assess the severity of infection with SARS-CoV-2 variants: scoping review and applications on Belgian COVID-19 data.
health. However, causally inferring the intrinsic severity of infection with variants using observational data is a challenging process on which guidance is still limited. We describe potential limitations ...
Severity of infection with the SARS-CoV-2 B.1.1.7 lineage among hospitalized COVID-19 patients in Belgium.
analyses were performed to assess the influence of selection bias, vaccination rollout, and unmeasured confounding. RESULTS: We observed no difference between the exposed and unexposed group in severe ...
Strategy and Performance Evaluation of Low-Frequency Variant Calling for SARS-CoV-2 Using Targeted Deep Illumina Sequencing
approach and Illumina sequencing. As anticipated, higher variation and lower sensitivity were observed at lower coverages and allelic frequencies. We found that detection of all low-frequency variants at an ...
