Study 1 - reverse cumulative distribution curves of anti-S. sonnei LPS antibody for subjects receiving ≥ 1.5/25 μg by IM route.

The grey line is the distribution prior to vaccination. Dots are the distribution on day 85 (i.e., 28 days post 3rd vaccination); triangles are the distribution on day 225 (i.e., 168 days post 3rd vaccination). Subjects received 1.5/25 μg (light orange), 2.9/50 μg (dark orange), or 5.9/100 μg (red). The purple line is the distribution of 87 convalescent subjects.
