Correlation analysis between functional signature and patient age. The correlation analysis between patient age and immune parameters was performed using Pearson’s correlation coefficient. The percentage of total lymphocytes (A), B cells (B), CD8⁺CD25⁺ T cells (C), CD8⁺PD‐1⁺ T cells (D), Tfh‐like cells (E) and GCB‐like cells (F) was correlated with age in COVID‐19 patient group. Each dot represents a single patient of COVID‐19 or healthy donor. Patients under the age of 15 years were excluded
