Filter by:Primary Objectives: 1. To present the safety profile after a 5th dose of DAPTACEL® in children 4 to 6 years of age who have previously received 4 doses of DAPTACEL® or Pentacel™. 2. To present the pre-Dose 5 and post-Dose 5 antibody responses to the antigens in DAPTACEL® in children 4 to 6 years of age who have previously received 4 doses of DAPTACEL® or Pentacel™. Observational Objectives: 1. To compare under equivalence criteria the pre-Dose 5 and post-Dose 5 antibody responses to the antigens in DAPTACEL® in children 4 to 6 years of age who have previously received 4 doses of DAPTACEL® or Pentacel™. 2. To present the pre-vaccination anti-poliovirus GMTs and seroprotection rates. 3. To present the post-vaccination anti-poliovirus GMTs and seroprotection rates among subjects receiving a 4th dose of IPV concurrently with the 5th dose of DAPTACEL and a 2nd dose of MMR.
The overall aim of the study is to corroborate that a schedule consisting of 3 doses of Pentacel™ and a 4th dose of DAPTACEL® and ActHIB® or 4 doses of Pentacel™ or 4 doses of Quadracel and ActHIB® is as safe and immunogenic as a standard of care schedule based on 3 doses of the licensed-equivalent vaccines DAPTACEL®, Vero cell derived Inactivated Poliovirus vaccine (IPOL®), and ActHIB® and a 4th dose of DAPTACEL® and ActHIB®.
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.
The present clinical study will assess the immunogenicity and reactogenicity 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 in order to meet the requirements for application for the use of the product in the Expanded Program on Immunization (EPI) in South Africa.
The present clinical study will assess the immunogenicity and reactogenicity of the subsequent administration of Aventis Pasteur's DTacP-IPV//PRP~T combined vaccine (PENTAVAC™/PENTAXIM), as a three-dose primary vaccination in 6, 10 and 14 weeks of age schedule followed by a booster vaccination during the second year of life with the aim to cover the WHO EPI primary vaccination schedule at this age for diphtheria, tetanus, pertussis, poliomyelitis and Hib vaccines. WHO EPI vaccination schedules for hepatitis B (either 0, 6 and 14 weeks or 6, 10 and 14 weeks of age) will be also assessed in infants born to HBsAg seronegative mothers. To assess the safety of Pentaxim.
This study will be conducted in two stages. In the diphtheria, tetanus, pertussis (DTP) booster phase, subjects will receive a booster dose of Tritanrix-HepB/Hib-MenAC or Tritanrix-HepB/Hiberix (active control) at 15 to 18 or 24 months in a single-blind manner so that the subjects' parents will not know which vaccine was administered to their child. In the Mencevax ACWY phase at 24-30 months, a dose of Mencevax ACWY will be given in an open manner to only those subjects who received less than 4 doses of Tritanrix-HepB/Hib-MenAC. No blood samples will be taken in this safety study.
The primary purpose of this study is to demonstrate the lot-to-lot consistency of 3 production lots of GSK Biologicals' Hib-MenAC (Haemophilus influenzae type b and meningococcal serogroups A and C) vaccine when reconstituted with Tritanrix™-HepB (diphtheria, tetanus, pertussis, and hepatitis B) vaccine and administered as a single injection.
To assess the immune memory following primary vaccination of DTPw-HBV/Hib vaccine and to assess immunogenicity and reactogenicity of a booster dose given at 15 - 18 months of age.
OBJECTIVES - General: To investigate the immunological background for the non-specific effects of diphtheria-tetanus-pertussis (DTP) and measles vaccines on child mortality - Specific: Examine the cytokine responses and possible association with morbidity in a study of DTP vaccinated children who will be randomised to receive a measles vaccine or no vaccine at 4½ months of age. (All children will receive a measles vaccine at 9 months of age)
The purpose of this study is to learn whether or not giving a tetanus/diphtheria vaccination ("tetanus shot") before giving pneumococcal vaccine makes the pneumococcal vaccine more effective without causing too many side effects.
