Figure 1. Influenza A IgG and IgM levels in hematopoietic cell transplant (HCT) patients (A) and healthy adults (B).

Figure 1

Serum from day 0 (d0) pre-vaccination or day 180 (d180) post-vaccination for healthy adults or d0 and day 30 (d30) and d180 post-vaccination for HCT patients was tested by ELISA for IgG and IgM specific for Influenza A. Black error bars represent the standard deviation from the mean (dashed bar). The p values are calculated using a two-tailed Mann-Whitney test. Healthy subjects showed sustained increases in both IgG and IgM levels at d180 post-vaccination. In HCT patients IgG and IgM levels were elevated at d30 post-vaccination, but for IgM the Ab level had returned to baseline by d180 post-vaccination. * = p<.05, ***=p<.001
