Bacteria virus illustration

Caption

This illustration shows SA (golden spheres) and various antigens and antibodies. Dominant antigens (purple) cause SA to produce non-protective antibodies (red with purple tips). These nonprotective antibodies outcompete antibodies derived from vaccination (green with purple tips). Vaccines targeting subdominant antigens (blue) could help yield more protective antibodies (green with blue tips), making the vaccine more effective.
