Affinity distributions of T cells recognizing SARS-CoV-2- (A) vs. EBV peptides (B).
| A | SARS-CoV-2 Peptide Pool Positive (%) | |||
|---|---|---|---|---|
| Aff. Level | Definition | Color Code | COVID-Recovered Subjects | Pre-COVID Era Subjects |
| 4 | 4 serial positives | 34% | 0% | |
| 3 | 3 serial positives | 7% | 1% | |
| 2 | 2 serial positives | 11% | 3% | |
| 1 | First positive only | 11% | 3% | |
| B | EBV Peptide Pool Positive (%) | |||
| Aff. Level | Definition | Color Code | COVID-Recovered Subjects | Pre-COVID Era Subjects |
| 4 | 4 serial positives | 31% | 17% | |
| 3 | 3 serial positives | 7% | 6% | |
| 2 | 2 serial positives | 7% | 6% | |
| 1 | First positive only | 10% | 12% | |
Peptide pools eliciting positive T cell recall responses in the specified affinity level categories are shown as the percentage of all positive responses within the cohort. The raw data are shown in Supplementary Table 5 for the SARS-CoV-2 peptides, and in Supplementary Table 6 for the EBV peptides.
