Time course of antibody responses from week 0 to week 8.

Each panel presents the time course of antibody responses for all 15 monkeys for one reactive antigen. The x-axis indicates the weeks since infection and the y-axis shows the normalized intensity after subtracting the week 0 intensity for each monkey. Mock control monkeys are shown with dark gray lines (n = 3), and infected monkeys (n = 12) are shown with red lines.
