Titer of serum antibody to each of the seven R. equi Vap proteins as measured in sera from a clinically normal foal over a 5-month period (the x axis indicates the days postparturition). Titers were determined by ELISA and expressed as natural logs. Mare serum was obtained on the day of parturition. This pattern was typical of the six foals maintained at pasture which remained apparently healthy over the course of the study.
