Filter by:This protocol posting deals with objectives & outcome measures of an extension phase when subjects are aged 3, 4 and 6 years of age. The objectives & outcome measures of the primary phase are presented in a separate protocol posting (NCT number = NCT00334334). The objectives & outcome measures of the booster phase are presented in a separate protocol posting (NCT number = NCT00463437). The purpose of this study is to evaluate the persistence of pneumococcal, meningococcal serogroup C, Hib and Hepatits B antibodies after booster vaccination, when the subjects are aged 3, 4 and 6 years. No vaccine will be administered during this persistence phase of the study.
The purpose of this Phase II study is to evaluate the feasibility of GSK Biologicals' GSK2197870A vaccine co-administered with Wyeth-Lederle's Prevenar™ when given in healthy infants as a three-dose primary vaccination course at 2, 3 and 4 months of age followed by a booster dose of GSK Biologicals' Menitorix™ at 12 months of age.
This study was designed to simulate meningococcal challenge by vaccination with a fractional combined dose of unconjugated meningococcal polysaccharides A, C, Y, and W-135, Menomune® in children who were vaccinated with one dose of TetraMenD at least 18 months earlier. Primary Objective: To evaluate and compare the antibody responses to a reduced dose of Menomune® in participants who had previously received a tetravalent meningococcal diphtheria toxoid conjugate vaccine to those responses in participants who received the same reduced dose of Menomune® but had not previously received any meningococcal vaccine.
To explore the potential benefit of the administration of Menactra vaccine as a two-dose regimen to children. Primary Objective: To assess, by age group, the immune response to Menactra vaccine after each vaccine injection.
The purpose of this Phase IIIb study is to evaluate the immunogenicity, reactogenicity & safety of GSK Biologicals' Hib-MenC vaccine (Menitorix™) when co-administered with GSK Biologicals' DTPa-HBV-IPV vaccine (Infanrix™ penta) & Wyeth's 7-valent pneumococcal conjugate vaccine (Prevenar™) in preterm infants as a 3-dose primary vaccination course during the first 6 months of life (at 2, 4, 6 months of age) and of a booster dose of Menitorix™ when co-administered with GSK Biologicals' DTPa-IPV vaccine (Infanrix IPV) and Wyeth's Prevenar in the second year of life (16-18 months of age). The control is a group of full-term infants receiving the same vaccines. The Protocol Posting has been updated in order to comply with the FDA Amendment Act, Sep 2007.
The purpose of this study is to evaluate the long-term antibody persistence at 12, 24 and 48 months after the administration of a booster dose of Menitorix™, given at 12-15 months of age. The children had previously received 3 doses of Menitorix™ and Infanrix IPV™ or Meningitec™ and Pediacel™ in infancy. In addition, the antibody persistence is to be investigated in children of 40-43 months of age who received a 3-dose primary vaccination of a MenC conjugate vaccine and a Hib containing vaccine in infancy without a booster dose of MenC conjugate and Hib vaccine in the second year of life. This protocol posting deals with objectives & outcome measures of the extension phases at 12, 24 and 48 months after the booster phase.

This study will be conducted among adolescents in Saudi Arabia who previously received one dose of A, C, Y, W 135 and at least one dose of A, C meningococcal polysaccharide vaccine. This study will evaluate the booster administration of Menactra® (Meningococcal A, C, Y, and W 135 Polysaccharide Diphtheria Toxoid Conjugate vaccine) compared with Mencevax® (Meningococcal A, C, Y, and W 135 Polysaccharide vaccine)in terms of their serum bactericidal antibody responses.
The purpose of this primary vaccination phase is to demonstrate the non-inferiority of two doses of Biologicals' Hib-MenC conjugate vaccine when given with Infanrix™ penta to infants (at 3 & 5m) compared to NeisVac-C™ given with Infanrix™ hexa. The purpose of the booster vaccination phase is to evaluate the immunogenicity, safety and reactogenicity of a booster dose of the Hib-MenC vaccine given with Infanrix™ penta at 11 m of age versus NeisVac-C™ given with Infanrix™ hexa, as well as the antibody persistence prior to the administration of the booster doses. The Protocol Posting has been updated in order to comply with the FDA Amendment Act, Sep 2007.
The purpose of the primary phase of the study is to demonstrate the non-inferiority of a single dose of GSK Biologicals' Haemophilus influenzae type b and meningococcal C (Hib-MenC) conjugate vaccine when given in the second year of life to subjects primed in infancy with a Hib vaccine, but not with a meningococcal serogroup C vaccine, versus commercially available Hib and MenC vaccines. In the extension phase, at Years 1, 2, 3, 4 & 5, one blood sample is taken at each year to follow the antibody persistence up to 5 years after vaccination. No additional vaccine is administered during the extension phase. The Protocol Posting has been updated in order to comply with the FDA Amendment Act, Sep 2007.
The purpose of this study is to evaluate the immunogenicity, safety and reactogenicity of a booster dose of the Hib-MenC conjugate vaccine when given to healthy subjects aged 13 to 14 months who were primed with three doses of Hib-MenC compared to a booster dose of Infanrix hexa given to subjects primed with three doses of Infanrix hexa and Meningitec.
