A new vaccine offers a single booster immunization against pertussis (whooping cough), in combination with tetanus and diphtheria, for adolescents and adults 11 to 64 years of age. The vaccine will be marketed as Adacel™ by Aventis Pasteur, Ltd., in Toronto, Canada.
This is the first vaccine approved as a pertussis booster for adults. Vaccines for the prevention of tetanus and diphtheria (Td vaccine) in adolescents and adults have been available for many years. The product is a tetanus toxoid (T), reduced diphtheria toxoid (d) and acellular pertussis vaccine (ap), adsorbed. It contains the same components as Daptacel® (Aventis Pasteur), a DTaP vaccine for infants and children, but the diphtheria toxoid and one of the pertussis components are in reduced quantities.
