View clinical trials related to Haemophilus Infections.
Filter by:Haemophilus influenza type b (Hib) remains a serious global health threat associated with high mortality and morbidity in young children. In China, The overall impact of Hib-related infections and the extent of coverage of Hib conjugate vaccines are unclear.Generally, vaccination has been considered the most effective way to prevent infection against Hib.In order to evaluate safety and immunogenicity of a haemophilus influenzae type b (Hib) conjugate vaccine developped by Chengdu Olymvax Biopharmaceuticals Inc. a phase III clinical trial is planned to conduct in healthy infants and children in China.
This is a study to show that vaccination with three doses of Quinvaxem presented in Uniject is not inferior to vaccination with three doses of Quinvaxem presented in single dose vials, with respect to protection against all antibodies (anti-hepatitis B surface antibodies, anti-polyribosyl ribitol phosphate (PRP), anti-diphtheria, anti-tetanus and anti-Bordetella pertussis) one (1) month after completion of the 6-10-14 week vaccination course.
The aim of this study was to evaluate the immunogenicity and safety of the Quinvaxem vaccine (a liquid combination vaccine against diphtheria, tetanus, B. pertussis, hepatitis B and H. influenzae Type B). Healthy Vietnamese infants received three doses of vaccine at 2, 3 and 4 months of age according to the local Expanded Programme on Immunisation (EPI) schedule
This is a study to show that vaccination with 1 dose of Tritanrix HB+Hib followed by Quinvaxem vaccine as the 2nd and 3rd dose is not inferior to vaccination with Quinvaxem for all 3 doses, with respect to protection against all antibodies (anti-hepatitis B surface antibodies, anti-polyribosyl ribitol phosphate (PRP), anti-diphtheria, anti-tetanus and anti-Bordetella pertussis) 1 month after completion of the 6-10-14 week vaccination course.
To monitor the occurrence of invasive Hib disease over time and to determine product-specific rates of invasive Hib disease within the monitored population.
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.
