Validation of 'Corona-T-test' for Assessment of SARS-COV-2-specific T-cell Response After COVID-19 or Vaccination

The investigators enrolled three independent cohorts of vaccinated (n = 69), convalescent (n = 50), and healthy but unvaccinated individuals (n = 101). Further, they estimated the T cell response to the designed peptide antigen panel, as measured by the manufactured ELISpot-based in vitro diagnostic 'Corona-T-test' to detect SARS-CoV-2-specific T cells.
