Roche anti-S SARS-CoV-2 total immunoglobulin results in VD administered Moderna (blue) and Pfizer (green) vaccinations, as compared to HSCT (orange) recipients and CPD (black). Distribution of VD samples are shown as a function of time after D1 or D2 in weeks. Statistically significant differences in antibody concentrations were observed between donors receiving Moderna and Pfizer vaccinations for all timepoints beyond the initial dose (p < 0.0001) and strong responses were seen for both vaccination type cohorts more than five months post series completion. HSCT demonstrated significantly lower antibody responses from healthy VD (Moderna and Pfizer combined) at both D2 and D2 + 4 (p < 0.0001).
