Tetanus-specific serum antibodies increased after vaccination. Tetanus toxoid-specific serum antibodies were quantified by ELISA before and after booster vaccination. Serum concentrations of (A) pan-Ig, (B) IgG1, (C) IgG3/5, and (D) IgG4/7 are plotted for each horse and time point. Connecting lines represent medians of n=6 (day 28 n=4). Compared to pre-vaccination (day 0) the concentrations of each isotype were statistically significantly increased (p<0.05, except IgG3/5 on day 28 p=0.08) at all time points after vaccination (not depicted).
