The percentage of participants meeting Ab response rates for V14 antigens was determined after V114 Dose 3. Antibody response rate criteria for Haemophilus influenza Type B (PRP); hepatitis B (HBsAg); diphtheria; tetanus; and polio types 1, 2, and 3 are shown in the rows below. The percentage of seroresponders to pertussis seroresponders (pertussis toxoid [PT]; filamentous haemagglutinin (FHA); fimbrae types 2 and 3 [FIM]; and pertactin [PRN]) was determined as 1) if pre-vaccination Ab concentration <lower limit of quantification (LLoQ) but post-vaccination Ab concentration ≥LLoQ; or 2) if pre-vaccination Ab concentration was ≥LLoQ but post-vaccination Ab concentration was ≥pre-immunization levels. Antibody titres were measured by RIA for PRP, enhanced chemiluminescence assay (ECi) for HBsAg, micrometabolic inhibition test (MIT) for diphtheria and poliovirus, and enzyme-linked immunosorbent assay (ELISA) for tetanus, PT, FHA, FIM, and PRN.
