Filter by:Objectives: - To present the rates of adverse reactions after a dose of DAPTACEL® vaccine administered to children 4 to 6 years of age who have previously received four doses of PENTACEL™ vaccine. - To present immunogenicity before and after a single dose of DAPTACEL® vaccine administered to children 4 to 6 years of age who have previously received four doses of PENTACEL™ vaccine.
This study is designed to evaluate in a controlled manner the effect of Prevnar® on the immune responses of Pentacel™ Primary Objective - Stage I: To compare the immune responses elicited by an infant series of Pentacel™ when given at different times from or concurrently with a Pneumococcal conjugate vaccine (Prevnar®). Primary Objective - Stage II: To compare the immune responses elicited by a 4th dose of Pentacel™ when given at different times from or concurrently with Prevnar®.
The purpose of this survey is to collect selected safety data. Primary Objective: To collect selected safety data at 6 months following the 4th dose of the Pentacel® series.
This will be an observational study where parents/ guardians of children in receipt of their preschool booster will be approached for their child(ren) to take part. Following written informed consent the Vaccine Research Nurse will explain the purpose of the study and what would be involved. Participation will involve completion of a health diary for the week following vaccination to document how their child has been both in terms of local reactions and systemic symptoms as well as any visits to a doctor (GP or hospital). The nurse will telephone the family at 48−72 hours following vaccination to see how the child has been. Information about the vaccine given in the current campaign and vaccines administered in the infant schedule including date of administration, product and batch number will be recorded where available. Should any large local reactions be reported the nurse may visit the child to take a photograph to document and illustrate these - photographs will be taken without the child's face visible. Subjects will be recruited in two centres - Hertfordshire and Gloucestershire. Recruitment will start as soon as the necessary approvals are in place. Monthly reports of observed data will be submitted to the MHRA though the formal analysis will not be conducted until the end of the study. Recruitment figures and the incidence of ESLs will be reviewed on a six−monthly basis. At this point it is difficult to predict parental attitude to taking part, though from experience with recruitment in previous studies it is hoped this will be positive, so affording a large number of participants.
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. The links to objectives and outcome measures of the primary phase & booster phase at 12 to 15 months are provided below: https://www.gsk-studyregister.com/study/2747 (Primary phase) https://www.gsk-studyregister.com/study/2755 (Booster phase)
Primary Objective: - To demonstrate that ProQuad® can be administered concomitantly with a booster dose of Infanrix® hexa to healthy children 12 to 23 months of age without impairing either the antibody response rates to measles, mumps, rubella, varicella, hepatitis B and Haemophilus influenzae type b; or to the 3 pertussis antibody titres measured at 42 days following vaccination. Secondary Objectives: - To describe the antibody titres and the antibody response rates to measles, mumps, rubella, varicella, diphtheria, tetanus, pertussis, hepatitis B, poliomyelitis and Haemophilus influenzae type b as measured at 42 days following vaccination by an Infanrix® hexa primary series schedule and all data are pooled. - To evaluate the safety profile of ProQuad® when administered concomitantly with a booster dose of Infanrix® hexa by an Infanrix® hexa primary series schedule and all data are pooled.
The primary phase of this study is evaluating the safety of Hib-MenCY-TT vaccine compared to a control group receiving licensed Hib conjugate vaccine, when each are co-administered with Pediarix® to healthy infants at 2, 4, and 6 months of age. This protocol posting deals with objectives & outcome measures of the primary phase of the study. The objectives & outcome measures of the Booster phase are presented in a separate protocol posting (NCT number = 00345683). The Protocol Posting has been updated in order to comply with the FDA Amendment Act, Sep 2007
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 present clinical study will assess the immunogenicity as the primary objective and the reactogenicity as the secondary objective of Aventis Pasteur's DTacP-IPV// PRP~T combined vaccine (Pentavac™ or Pentaxim™) as a three-dose primary vaccination at 6, 10 and 14 weeks of age followed by a booster dose during the second year of life. Safety: This study will describe the safety after each dose of the primary series of the study's combined vaccine (Pentaxim™).
The present clinical study will assess the immunogenicity and reactogenicity of Sanofi Pasteur's DTacP-IPV// PRP~T combined vaccine (Pentavac™ or Pentaxim™) as a three-dose primary vaccination at 2, 4, and 6 months of age followed by a booster dose during the second year of life and concomitant hepatitis B vaccine at 2 and 6 months of age in infants in Thailand.
