ASYMP COVID-19 patients showed significantly higher frequencies of SARS-CoV-2 epitope-specific IFN-γ-producing CD8+ T cells (mean SFCs > 25 per 1 × 106 pulmonary immune cells), irrespective of infection with Beta (p < 0.5, Figure 1B, left panel) or Omicron (p < 0., Figure 1B, right panel) variants. The gene discussed is CD8A; the disease is COVID-19.
