Serum antibody titers after different immunization stages. (a) Anti-TT IgG titers in serum; (b) anti-TeNT-Hc IgG titers in serum; (c) anti-TT IgM titers in serum; (d) anti-TeNT-Hc IgM titers in serum. Unpaired two-tailed Student’s t-test was used to determine the significance of the differences in antibody titers between the groups. P values ≤ 0.05 were considered to be significant.
