CD79A and infection: Both infection and vaccination induced binding IgG and IgA (Supplemental Figure 1, A and B) and neutralizing antibodies (Supplemental Figure 1C), as early as 2 weeks following the first dose of vaccine; antibody levels increased several-fold following booster vaccination (Supplemental Figure 1C) and reached slightly higher levels than those achieved following asymptomatic/mild infection (P = 0.09).
