Post-vaccination SARS-CoV-2 IgG spike antibody responses among clinical and non-clinical healthcare workers at a tertiary facility in Kenya.

Introduction: Following the coronavirus disease 19 (COVID-19), caused by severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) infection, vaccination became the main strategy against disease severity and even death. Healthcare workers were considered high-risk for infection and, thus, were prioritised for vaccination.

Methods: A follow-up to a SARS-CoV-2 seroprevalence study among clinical and non-clinical HCWs at the Aga Khan University Hospital, Nairobi, we assessed how vaccination influenced SARS-CoV-2 anti-spike IgG antibody responses and kinetics.

SARS-CoV-2 Variants Genotyping and Diagnostic Performance of a 2-Genes Detection Assay.

Background: The emergence of the COVID-19 pandemic resulted in the unprecedented expansion of molecular testing technologies. This study aimed at evaluating the performance of the FluoroType® SARS-CoV-2 plus assay for SARS-CoV-2 detection as well as describing the detection of SARS-CoV-2 variants using the FluoroType® SARS-CoV-2 varID Q kit.

Methods: The study utilized 679 archived nasopharyngeal samples.
