Anti-HBs titers and strength of IFNγ response correlate in hepatitis B vaccinated HC. Scatter plot of IFNγ release of HepB vaccinated HC vs. anti-HBs titers after stimulation of whole blood with a HBsAg alone (n = 87), b HBsAg and C3a (n = 80), c HBsAg and C5a (n = 74) as well as d HBsAg, C3a and C5a (n = 55). Antigen induced cytokine responses were corrected by the negative control values. Continuous line indicates linear regression and Pearson correlation. R2: coefficient of determination
