Filter by:The purpose of this study is to show that the immunogenicity of newly formulated DTPa-HBV-IPV/Hib vaccine is as good as the immunogenicity of the currently licensed formulation of the vaccine. The vaccine will be administered as a primary vaccination course to healthy infants at 2, 3 and 4 months of age and its safety and reactogenicity will also be assessed.
PR5I, a hexavalent pediatric combination vaccine is being developed to reduce the number of injections during the first 2 years of life while providing a complete course of immunization against infection caused by H. influenzae type b, hepatitis B virus, Corynebacterium diphtheriae, Clostridium tetani, Bordetella pertussis, and poliovirus types 1, 2, and 3. Primary Objective: To evaluate immunogenicity of PR5I with the adjuvant composition enhancement to the hepatitis B component when administered concomitantly with Prevnar® Secondary Objectives: To assess the safety and immunogenicity of PR5I when administered concomitantly, or one month apart with Prevnar® or separately with licensed vaccines used for routine infant vaccination in Canada.
The purpose of this study is to document the immunological response to the investigational hexavalent vaccine at the 6, 10, and 14 weeks schedule The primary objective is to demonstrate that the hexavalent DTaP-IPV-HB-PRP~T combined vaccine does not induce lower immune responses than CombAct-HIB® with Engerix B® Paediatric and OPV in terms of seroprotection rates to Diphtheria (D), Tetanus (T), polio, Hepatitis B (HB), and Polyribosyl ribitol phosphate (PRP), one month after a 3-dose primary series (6, 10, and 14 weeks) with no HB vaccination at birth. The secondary Objectives are: To describe the safety in terms of any adverse events in the first 28 days after each injection and any serious adverse events during the entire trial. To describe Immunogenicity after the primary series and prior to and after a booster vaccination.
The purpose of this study is to evaluate the immunogenicity and safety of the concomitant administration of Menactra® vaccine and DAPTACEL® vaccine. The main objectives are: Immunogenicity: To evaluate the antibody responses to both vaccines when Menactra vaccine is given concomitantly with DAPTACEL® compared to when either vaccine is given alone. Safety: To evaluate the rate of local and systemic reactions when DAPTACEL® and Menactra vaccines are administered concomitantly compared to when each vaccine is given alone.
This study will evaluate the immunogenicity of the co-administration of different combinations of DTPa, IPV, hepatitis B, Hib and Men C vaccines during the first year of life.
This is a study to compare the safety and immune response of a pentavalent DTaP-HB-PRP~T combined vaccine with Tritanrix-HepB/Hib™, when both are given concomitantly with OPV at 6, 10, and 14 weeks of age.
Objectives: To provide safety data on revaccination with ADACEL® vaccine. To describe the immune response to tetanus, diphtheria, and pertussis antigens following revaccination with ADACEL® vaccine 4-5 years after first vaccination.
GSK Biologicals' dTpa vaccine has recently been approved by the US Food and Drug Administration (FDA) for booster vaccination of adolescents aged 10 to 18 years. The ACIP has recently issued provisional recommendations for universal adult Tdap vaccination. The current study will provide pivotal data in support of extending the age range for Boostrix vaccine to include adults 19-64 years of age.
The purpose of this study is to support the registration of the pentavalent DTaP-HB-PRP~T vaccine in countries that follow the World Health Organization-Expanded Program of Immunization (WHO-EPI) schedule. The primary objective is: - To demonstrate that the pentavalent DTaP-HB-PRP~T combined vaccine does not induce a lower immune response than Tritanrix-HepB/Hib™ in terms of the seroprotection rate to hepatitis B (HB) one month after a 3-dose primary series at 6, 10, and 14 weeks of age. The secondary objectives are: - To describe in each group the immunogenicity parameters one month after the 3-dose primary series at 6, 10, and 14 weeks of age; and - To evaluate the overall safety in terms of any adverse events in the first 28 days after each injection and any serious adverse events during the entire trial.
The purpose of this study is to evaluate safety and immunogenicity of Pediacel® in infants and toddlers when given at 2,3,4 and 12-18 months of age. Primary Objectives: - To compare the post-dose 3 immunogenicity of Pediacel® to Infanrix®-IPV+Hib when both are co-administered with Prevenar®. - To describe the post-dose 3 pertussis antibody responses. Secondary Objectives: - To compare the post-dose 4 immunogenicity of Pediacel® to Infanrix®-IPV+Hib when both are co-administered with Prevenar®. - To describe the safety after each vaccination following co-administration with Prevenar®.
