DAPTACEL®, Diphtheria and Tetanus Toxoids and Acellular Pertussis Vaccine Adsorbed, for intramuscular use, manufactured by Aventis Pasteur Limited, is a sterile suspension of pertussis antigens and diphtheria and tetanus toxoids adsorbed on aluminum phosphate in a sterile isotonic sodium chloride solution. After shaking, the vaccine is a white homogeneous cloudy suspension. Each dose of DAPTACEL® contains the following active ingredients:
DAPTACEL® is indicated for active immunization against diphtheria, tetanus and pertussis in infants and children 6 weeks through 6 years of age (prior to seventh birthday).
Children who have had well-documented pertussis (culture positive for
or epidemiologic linkage to a culture positive case) should complete the vaccination series with DT; some experts recommend including acellular pertussis vaccine as well. Although well-documented pertussis disease is likely to confer immunity, the duration of protection is unknown.17
DAPTACEL® is not to be used for the treatment of
B. pertussis, C. diphtheriae or C. tetani
When passive protection is required, Tetanus Immune Globulin and/or Diphtheria Antitoxin may also be administered at separate sites with separate needles and syringes.4(See DOSAGE AND ADMINISTRATION.)
As with any vaccine, vaccination with DAPTACEL® may not protect 100% of susceptible individuals.
Published Studies Related to Daptacel (Diphtheria / Tetanus / Pertussis)
A modified vaccine reduces the rate of large injection site reactions to the preschool booster dose of diphtheria-tetanus-acellular pertussis vaccine: results of a randomized, controlled trial. [2005.12]
BACKGROUND: Large injection site reactions commonly follow booster doses of diphtheria-tetanus-acellular pertussis (DTaP) vaccines at 4-6 years of age. A vaccine with lower diphtheria and pertussis dosage (Tdap) might be better tolerated for this dose... CONCLUSIONS: This preschool DTaP.IPV booster vaccination caused large local reactions in 1 in 5 children, with transient discomfort. With Tdap vaccine, such reactions were significantly fewer but not eliminated. A Tdap.IPV vaccine warrants study for routine use at 4-6 years of age.
Tetanus immunity after diphtheria, tetanus toxoids, and acellular pertussis vaccination in children with clinically stable HIV infection. [2005.09]
BACKGROUND: HIV infection often impairs the immune response to childhood vaccines. OBJECTIVE: We sought to study the ability of HIV-infected children receiving highly active antiretroviral therapy (HAART) to generate a booster response to immunization with a recall antigen to which they had lost humoral immunity... CONCLUSION: Although children with stable HIV infection receiving HAART can mount antigen-specific responses to tetanus immunization, the durability of these responses might be limited. Long-term monitoring of specific immune function in such children is indicated.
Combined tetanus, diphtheria, and 5-component pertussis vaccine for use in adolescents and adults. [2005.06.22]
CONTEXT: Increasing reports of pertussis among US adolescents, adults, and their infant contacts have stimulated vaccine development for older age groups. OBJECTIVE: To assess the immunogenicity and reactogenicity of a tetanus-diphtheria 5-component (pertussis toxoid, filamentous hemagglutinin, pertactin, and fimbriae types 2 and 3) acellular pertussis vaccine (Tdap) in adolescents and adults... CONCLUSIONS: This Tdap vaccine elicited robust immune responses in adolescents and adults to pertussis, tetanus, and diphtheria antigens, while exhibiting an overall safety profile similar to that of a licensed Td vaccine. These data support the potential routine use of this Tdap vaccine in adolescents and adults.
Reduced-antigen-content-diphtheria-tetanus-acellular-pertussis and inactivated polio vaccine as a booster for adolescents 10 to 14 years of age. [2005.06]
CONCLUSION: The combined reduced-antigen-content-diphtheria-tetanus-acellular-pertussis and IPV vaccine is immunogenic and well tolerated when administered to adolescents and could be used to improve the control of pertussis disease in this age group.
Immunogenicity and reactogenicity of combined acellular pertussis/tetanus/low dose diphtheria vaccines given as a booster to UK teenagers. [2005.05.31]
Sustained high incidence of pertussis, particularly amongst unvaccinated infants, is of concern. Inclusion of pertussis vaccination with tetanus and low dose diphtheria (Td) teenage boosters may protect individuals through reproductive years, and prevent transmission to offspring... This study demonstrated that addition of aP and/or IPV to Td vaccine did not materially alter reactogenicity or immunogenicity of Td components, and induced immune responses to pertussis antigens in teenagers who had received no pertussis vaccine since infancy.
Clinical Trials Related to Daptacel (Diphtheria / Tetanus / Pertussis)
Study of the Safety, Immunogenicity and Lot Comparability of DAPTACEL When Administered With Other Recommended Vaccine [Completed]
This study was designed to assess the lot comparability of DAPTACEL, as well as the safety
and immunogenicity of DAPTACEL when co-administered with other recommended infant vaccines.
Stage I Primary Objectives:
1. To assess the lot-comparability of immunogenicity of DAPTACEL by when co-administered
with other recommended vaccines.
2. To compare the immune response to DTaP-IPV/Hib (Pentacel) with those of three lots of
DAPTACEL when co-administered with other recommended vaccines.
3. To compare the immune response of PRP-T antigen in Pentacel with that of ActHIB
concurrently administered in a different injection site with DAPTACEL when these
vaccines are co-administered with other recommended vaccines.
Stage II Primary Objectives:
1. To compare the immune response of DAPTACEL when the 4th dose is co-administered with Hib
or other infant vaccines.
2. To compare the the immune response of Pentacel with those elicited by DAPTACEL when
co-administered with ActHIB in toddlers.

The purpose of this study is to generate immunogenicity and safety data of an
investigational hexavalent DTaP-IPV-Hep B-PRP-T vaccine compared to a control vaccine,
Infanrix hexa™ when given along with Prevenar™ and Rotarix™ vaccines.
