Conclusion: “Exposure to SARS-CoV-2 can + induce virus-specific T cell responses without seroconversion. T + cell responses may be more sensitive indicators of SARS-Co-V-2 + exposure than antibodies.

Main conclusion: “Data show that systemic + IgA and IgG production against SARS-CoV-2 develops mainly in severe + COVID-19, with very high IgA levels seen in patients with severe + ARDS, whereas mild disease may be associated with transient serum + titers of SARS-CoV-2-specific antibodies but stimulate mucosal + SARS-CoV-2-specific IgA secretion.
