YLQPRTFLL-specific T cells from vaccinees fail to stain with P272L variant tetramers

Ex vivo tetramer staining of PBMC from 7 vaccinees with HLA A^∗02:01-YLQPRTFLL and P272L tetramers. Vaccinee gender is indicated next to each donor code. Vaccinees received the AstraZeneca (AZ) ChAdOx1 nCov-19 vaccine or the BNT162b2 (BNT) vaccine as indicated. The number of days post vaccine when blood was taken is indicated for each vaccinee, with data for 0439 shown after the second dose of the vaccine. Tetramer enriched T cell lines were successfully created from 6 of the 7 vaccinees and used for further analysis (Figure 6).
