Percentages of antibody cross-reactivity. Percentages of antibody cross-reactivity in 2002 (a) and in 2007 (b). In 2002, antibodies against A/Wisconsin/67/05 were set to be 100% and the anti-A/Panama/2007/99 were compared to them, while in 2007, the A/Panama/2007/99 antibodies were set to be 100% and were compared with the A/Wisconsin/67/05 antibodies. * <0.0001 using Chi test.
