- [Pre-print, not peer-reviewed] A longitudinal study in California found that SARS-CoV-2-specific T cell responses remained largely stable up to 9 months following SARS-CoV-2 infection (n=70). Stronger CD4+ T cell responses were associated with initial disease severity as well as neutralizing antibody levels, whereas pre-existing lung disease predicted long-term CD8+ T cell responses. While 36% of participants had COVID-19-related symptoms persisting approximately 4 months after initial illness (median 125 days), no substantial differences in long-term T cell or antibody responses were identified between participants with or without persisting symptoms.
