claim: robust sars-cov-2-specific t-cell immunity is maintained at 6 days following primary infection
evidence_1: median t-cell responses were 50% higher in donors who had experienced an initial symptomatic infection indicating that the severity of primary infection establishes a setpoint for cellular immunity that lasts for at least 6 months.", "in conclusion, our data are reassuring that functional sars-cov-2-specific t-cell responses are retained at six months following infection although the magnitude of this response is related to the clinical features of primary infection.")
