Several common TRA and TRB pairs, such as TRAV1-2/TRAJ33, TRAV21/TRAJ49, TRBV6-4/TRBD2/TRBJ2-3, and TRBV5-1/TRBD1/TRBJ2-7, were consistently detected from the primary infection (PI) through the convalescent phase (HC) and into the reinfection phase (RI) (Supplementary Figure 7). Here, TRBV5-1 is linked to infection.
