Figure 3.

Line graphs showing antibody change in ELISA IgG levels across different groups at one and six months post-vaccination for two, three, and four doses. Groups include Healthy Control, Multiple Myeloma, non-MM hematological, and Solid, with corresponding median percentage changes and p-values indicated. Significant p-values are in red. Each panel shows distinct subsets with lines representing individual data points and group medians in red.

Percent change in anti-spike IgG levels from 1 month to 6 months post vaccination in cancer and healthy cohorts. Comparison of percent change in serum anti-spike IgG levels between 1 month and 6 months post-vaccination in individuals receiving 2 doses (A), 3 doses (B) and 4 doses (C) of vaccine in healthy, multiple myeloma, non-MM hematological cancer and solid cancer cohorts. Percent change results were reported as Median with the first and third quartiles (Q1 and Q3). The p values indicate the significance levels of the percent change between 1 month and 6 months in the cancer cohort, compared to the percent change observed in the healthy cohort with the corresponding doses. Solid red line represents the connecting line of geometric mean titer at 1 month and 6 months in each cohort. Differences assessed by non-parametric Wilcoxon rank sum test.
