Post-marketing evaluation of reactions following receipt of recommended adolescent pertussis vaccine among persons with prior vaccination with acellular vs whole-cell pertussis vaccine. To describe and characterize adverse events occurring after vaccination with REPEVAX® (Tdap-IPV: combination diphtheria, tetanus and acellular pertussis with inactivated poliomyelitis vaccine) or COVAXIS® (Tdap: combination diphtheria, tetanus and acellular pertussis) vaccine among two groups: Group 1 - adolescents 10-14 years of age who participated in study 371-03/01 (and thus received a 5th dose of TRIPEDIA® vaccine) and Group 2 - controls 10-14 years of age who were vaccinated with at least three doses of a whole-cell pertussis vaccine in infancy plus at least one subsequent dose of pertussis vaccine in their 2nd through 7th year of life.
This study will assess both the antibody persistence of the investigational vaccine and the immune response and safety of a booster dose of PENTAXIM™ vaccine in 18 months-old toddlers who participated in an earlier study in order to determine if they are still protected before they receive a booster dose of D, T, IPV, pertussis or Hib vaccines and also to assess the quality of the induced immune memory in response to a booster dose of the same vaccine as in the primary series. Primary Objective: To describe the antibody persistence at 18 months of age and the booster effect of a dose of PENTAXIM™ on immunogenicity. Secondary objective: To describe the safety profile of the booster dose PENTAXIM™ in each vaccine group defined by the vaccines received during the primary series.
Pre-licensure studies of GSK Biologicals' Boostrix® have shown it to be generally safe and well-tolerated. This post-licensure study is designed to evaluate relatively uncommon/rare outcomes in a large population cohort. The Protocol Posting has been updated in order to comply with the FDA Amendment Act, Sep 2007.
To compare three formulations of Hib-MenAC vaccines mixed with Tritanrix™-HepB vaccine with that of Tritanrix™-HepB vaccine concomitantly administered with GSK Biologicals’ Hiberix™ vaccine and Tritanrix™-HepB vaccine mixed with Hiberix™ vaccine and concomitantly administered with Wyeth Lederle’s meningococcal C conjugate vaccine (Meningitec™), with respect to antibody response to vaccine antigens (meningococcal serogroups A and C and PRP) after a three-dose primary vaccination course.
DTPa and IPV vaccines are recommended for immunization of infants in Korea. The use of combination vaccines simplifies routine paediatric vaccination. The Protocol Posting has been updated in order to comply with the FDA Amendment Act, Sep 2007.
The purpose of this study is to compare the immune response, safety and reactogenicity of Tritanrix™-HepB/Hib-MenAC vaccine given either with or without a birth dose of hepatitis B vaccine to Tritanrix™-HepB/Hiberix™ when given to healthy infants (born to mothers who do not carry hepatitis B virus) at 6, 10 & 14 weeks of age. This study will also include a small group of infants born to mothers who do carry hepatitis B virus; these infants will receive a birth dose of hepatitis B vaccine and will be vaccinated with Tritanrix™ HepB/Hib-MenAC at 6, 10 & 14 weeks age.
Pediacel™ is currently licensed in the UK for use as a 3 dose regimen for the active immunisation of infants against Diphtheria, Tetanus, Pertussis, Poliomyelitis and invasive infections caused by Haemophilus influenzae type b. However there are currently no clinical data supporting the use of Pediacel™ using a 3, 5, and 12 months of age vaccination schedule. This study is designed to provide safety and immunogenicity data to support the use of Pediacel™ according to a 3, 5, and 12 months schedule.
New immunization recommendations in the US include vaccination of adolescents against pertussis and meningococcal disease. The Advisory Committee on Immunization Practices of the Centers for Disease Control and Prevention recommends that Tdap (Tetanus Toxoid, Reduced Diphtheria Toxoid And Acellular Pertussis Vaccine Adsorbed) and MCV4 (Meningococcal conjugate vaccine against serotypes A, C, Y and W-135) vaccines be administered to adolescents at the same office visit if vaccination with both vaccines is indicated. Therefore, this study is designed to evaluate the safety and immunogenicity of a booster vaccination with Boostrix co-administered with Menactra as compared to the administration of either vaccine alone in healthy adolescents 11 - 18 years of age.
The aims of this study are to compare the immunogenicity and safety of the GSK Biologicals' combined DTaP-IPV vaccine with separate administration of DTaP and IPV vaccines, when administered as a fifth dose of acellular pertussis vaccine to children aged 4 to 6 years when co-administered with MMR vaccine in subjects who had previously received four doses of Infanrix, three doses of poliovirus-containing vaccine and MMR vaccination.
