Higher numbers of memory B-cells and Th2-cytokine skewing in high responders to hepatitis B vaccination

Since activation of the B-cell response after vaccination is induced by Th2 cells and IL-13 is produced by these cells, we conclude that the difference in HBsAg-specific Th2 cells is involved in determining the differences in anti-HBs level and memory B-cell numbers between low and high responders.
