“…Aleman et al evaluated the immune response to booster vaccination in 261 patients with MM [ 113 ]. The booster vaccine shot (BNT162b2 or mRNA-1273) significantly increased the anti-spike RBD antibodies, including patients with antibody levels below the positivity threshold before the administration of the third dose, which is in line with other studies [ 36 38 , 113 118 ]. Enssle et al evaluated the neutralizing activity against SARS-CoV-2 variants in 100 patients with MM; the booster shot led to sufficient neutralization titers against Delta and Omicron in 64% and 29% of the patients, respectively [ 118 ].…”

“…Furthermore, MM patients often show low/suboptimal rates (in terms of percentage of responders and magnitude of response) of both humoral and functional T-cell immune responses to anti-SARS-CoV-2 vaccines [ 31 – 34 ]; this further contributes to an increased risk of severe COVID-19, need of hospitalization and higher mortality rates [ 35 ]. Notably, an appropriate use of one [ 36 40 ] or two [ 41 , 42 ] “booster” doses may significantly improve vaccine performance, particularly among patients who failed to respond to the initial two doses with mRNA vaccines. However, several of these patients may still have vaccine failure due to severe immune impairment, particularly those who receive anti-BCMA treatments [ 39 , 41 ].…”

“…[39][40][41] In particular, vaccinated patients with ≥2 doses showed a better OS than those unvaccinated or having receives only one dose, highlighting the need of a complete cycle of vaccination, also in individuals with MM, particularly in those with scarce immune-reaction after the first two doses. [42][43][44][45] Notwithstanding, even full vaccinations, though statistically significant at univariable analysis, did not enter into the multivariable model, where other clinical variables, in particular age, active disease, and COVID-19 severity requiring hospital/ICU admission, had a major impact. In this setting, more recent VOC, 46 reduced production of neutralizing antibodies 47,48 and impaired T-cell response, 49 as well increasing hybrid 50…”

“…Overall, OS was significantly longer in vaccinated versus unvaccinated patients, including those with scarcely controlled disease, thus suggesting the possible efficacy of vaccines even in this population of patients, despite their generally described inadequate capacity of humoral immune response 39–41 . In particular, vaccinated patients with ≥2 doses showed a better OS than those unvaccinated or having receives only one dose, highlighting the need of a complete cycle of vaccination, also in individuals with MM, particularly in those with scarce immune‐reaction after the first two doses 42–45 . Notwithstanding, even full vaccinations, though statistically significant at univariable analysis, did not enter into the multivariable model, where other clinical variables, in particular age, active disease, and COVID‐19 severity requiring hospital/ICU admission, had a major impact.…”
