Supplementary Table 2A: Overview of specific spot counts. The reported frequencies of antigen-specific T-cells.expressed as spots per 100,000 PBMC, are shown for all 16 centres that submitted complete data sets for the sevendonor-antigen combinations where antigen-specific T cells were present in detectable numbers (D1/CMV, D2/Flu,D2/CMV, D3/Flu, D3/CMV, D4/Flu, D5/Flu). For each donor-antigen combination the results are shown for test withserum and without serum. Where insufficient cells were recovered to perform the test in triplicate the results wereeliminated from further analysis (not done, n.d.). A two-sided T-test for unpaired samples was performed on alltriplicates to eliminate variability through inconsistent seeding; triplicates with p-value of >0.05 are indicated in thetable as (P). Antigen-specific spots were determined where the number of spots provided by PBMC plus antigen were>3-fold of the medium only background; triplicates that were <3-fold background are indicated as (BG).

Supplementary Table 2B: Overview of specific spot counts.The table gives a summary of the group results (all 16 participants shown in suppl. Table 2A) for the seven reactivedonor-antigen combinations (D1/CMV, D2/Flu, D2/CMV, D3/Flu, D3/CMV, D4/Flu, D5/Flu). For each donor-antigencombination the group results are shown for test with serum and without serum. The table shows the number ofcentres that were successfully able to detect a response (first row), the number of tests performed (second row), thepercentage of centres that were able to successfully detect a response (third row), the mean frequency of antigen-specific T cells (fourth row), the standard deviation of reported frequency of antigen-specific T cells (fifth row) andthe coefficient of variation as calculated from all positive responses (sixth row).
