“…Another intriguing finding of this study is the fact that the moderate humoral responses were strictly accompanied by T cellular memory responses, which is in accordance with previous findings, that in the majority of vaccine non-responders also T cell responses are absent [ 21 ]. While it could have been assumed that T cell responses could have established themselves even in the absence of functional B cells, this was not what we found here.…”

“…In contrast, while CD3 + CD8 + T cells of the control subject strongly neo-expressed CD25 and CD69 upon incubation with S-peptide mix, this was not evident with CD3 + CD8 + T cells of the patient, indicating a potential scar in the respective repertoire. Recent reports confirmed these findings, showing that more patients and healthy controls mounted an efficient CD4+ T cell as compared to a CD8+ T cell response [ 21 ].…”

“…Hematological malignancies were associated with lower vaccine response than solid malignancies, consistent with other reports 15,16,20,22,26,27 . Interestingly, patients with a history of B cell lymphomas or plasma cell diseases, not on ISMT, had low rates of humoral response but high rates of cellular response, while those with a history of acute leukemias, such as B lymphoblastic leukemia, had high rates of both humoral and cellular response.…”

“…23,24,33,34 Until now, only two groups described variable results on the antigen-specific cellular responses in the MM setting. In fact, Aleman et al 11 highlighted that fully vaccinated seronegative MM patients had a reduction in the percentage of spike-specific CD4 + T cells compared to the seropositive patients. On the other hand, another study on MM patients showed a significant lower percentage of spike-specific CD8 + INF-γ + T cells in the seronegative group.…”

“…7,8 In addition, MM patients treated with anti-CD38 or anti-B-cell maturation antigen (BCMA) antibodies, seem not to develop anti-SARS-CoV-2 antibodies or have insufficient response even after full vaccination. 9,10 However, very few data are actually available about the cellular response to SARS-CoV-2 mRNA vaccination 11 and the efficacy of the mRNA vaccine, including the booster dose, to the different SARS-CoV-2 variant characterized by mutations encoding for the spike protein. 12 Since November 2021, the B.1.1.529 (Omicron) variant has rapidly become dominant globally.…”
