Abstract

Three hundred and nineteen adolescents aged 10-12 years who had been previously vaccinated with five doses of acellular pertussis-containing vaccines received single doses of Tdap (reduced-antigen-content tetanus, diphtheria, acellular pertussis) and hepatitis A vaccines in a double-blind crossover trial. Long-term antibody persistence following vaccination with Tdap at pre-school age was similar to that following vaccination with DTaP (diphtheria-tetanus-acellular pertussis). After the sixth dose booster, Tdap induced a vigorous immune response, consistent with protection against diphtheria, tetanus and pertussis diseases.
