Hide Description

Seroconversion was defined as a ≥4-fold increase in antibody levels from Baseline. For values below the limit of quantification (LLQ) for the assay, the LLQ was used.

Serum anti-toxin IgG levels were determined by enzyme linked immunosorbent assay (ELISA).

Time Frame Days 28, 56, 70, and 236 Post First Vaccination
