Objective Evidence regarding the role of cellular immunity in protecting against COVID-19 is
emerging. To better assess immune status, simple and robust assays measuring specific T …

Background The reliable detection of T cell response to COVID-19 or COVID-19 vaccination
is important for individual patient care and for monitoring the immune response eg in COVID …

Background The reliable detection of the T-cell mediated response to COVID-19 or COVID-
19 vaccination is important for individual patient care and for monitoring the immune …

Cellular immunity against SARS-CoV-2 is an important component of the immune response
to the virus. At present, two such tests based on interferon-gamma release (interferon-γ …

Objectives: In this study, we aimed to characterize the SARS-CoV-2-specific T cell response
detected by the QuantiFERON SARS-CoV-2 research use only assay in terms of accuracy …

The SARS-CoV-2 IGRA assay used in this study accurately distinguished convalescent
COVID-19 patients and vaccinated subjects of uninfected controls, and correlated with the …

Background Clinical trials on the different vaccines to SARS-CoV-2 have demonstrated
protection efficacy, but it is urgent to assess the levels of protection generated with real …

Introduction There is an increasing body of evidence surrounding the importance of a T cell-
mediated response to SARS-CoV-2 infection and after COVID-19 vaccination. In this internal …

We explored the performance of a whole blood interferon gamma release assay (IGRA)
based on the stimulation of SARS-Cov2-specific T cells by purified recombinant proteins …

Background We evaluated a standardized interferon-γ (IFN-γ) release assay (IGRA) for
detection of T-cell immune response after severe acute respiratory syndrome coronavirus 2 …
