Filter by:This study is designed to evaluate the safety and immunogenicity of Infanrix™-IPV+Hib vaccine when administered as a primary vaccination course to healthy Korean infants at 2, 4 and 6 months of age.
Primary objective: - To demonstrate that 3 doses of a vaccine containing Td-IPV valences administered in a 0, 1 and 6-month schedule induce an acceptable immune response in terms of seroprotection rates (SPR) against diphtheria, tetanus and poliomyelitis 1, 2 and 3, in subjects of 40 years of age or older with no diphtheria- and tetanus-containing booster within the last 20 years - To evaluate the percentage of subjects with antibody titre ≥5 EU/mL (ELISA) for each of the pertussis components (PT, FHA, PRN and FIM) after 1 dose of REPEVAX in these subjects Secondary objectives: - If the primary objective is achieved, to determine whether 1 or 2 doses of a vaccine containing Td-IPV valences induce an acceptable response in terms of seroprotection rates (SPR) against diphtheria, tetanus and poliomyelitis 1, 2 and 3, in subjects of 40 years of age or older with no diphtheria- and tetanus-containing booster within the last 20 years - To describe the immune responses to REPEVAX in these subjects - To describe the immune responses to REVAXIS administered 1 and 6 months after the administration of REPEVAX in these subjects
The aim of the study is to collect post marketing safety data on IMOVAX Polio vaccine in China. Objective: To describe serious adverse events 30 days after each dose of IMOVAX Polio™ administered at 2, 3, and 4 months of age among infants living in the study cities of China.
Primary objectives: To demonstrate that REPEVAX and VAXIGRIP administered concomitantly in subjects 60 years of age and older are at least as immunogenic as REPEVAX or VAXIGRIP administered separately. Secondary objectives: •Secondary immunogenicity objectives: To describe the immune responses 28 days after concomitant or separate administration of REPEVAX and VAXIGRIP in subjects 60 years of age and older To describe the immune response of VAXIGRIP according to European Medicines Agency criteria in subjects 60 years of age and older (Note for Guidance, 1997: 28) •Secondary safety objective: To describe the safety profile after vaccination in each group
This study is designed to evaluate the safety and immunogenicity of new formulations of GSK Biologicals' DTPa-HBV-IPV/Hib vaccine (GSK217744) when administered as a primary vaccination course to healthy infants at 2, 3 and 4 months of age.
The purpose of the study is to compare the immunogenicity and safety of a booster dose of BoostrixTM Polio to that of Sanofi Pasteur MSD's RepevaxTM, when co-administered with a second dose of PriorixTM, in healthy 3 and 4-year-old children.
This study is designed to obtain post-marketing safety data on IMOVAX Polio™ vaccine in China. Primary Objective: To describe the safety profile after each dose of IMOVAX Polio™ administered at 2, 3, and 4 months of age in population aged over 2 months old living in the study city China.
Pakistan is one of the 4 developing countries where cases of poliomyelitis are still being identified. Despite the incessant efforts by WHO and UNICEF, this disease is far from control. There is a need to develop new and innovative strategies to contain the disease and eradicate it from the countries where new cases continue to be identified. Zinc is an essential component of scores of enzymes in the human body. Recent reports have indicated that this trace element along with other micronutrients enhances the protective functions of immune cells. Moreover, zinc deficiency leads to dysregulation of balanced host responses to infection resulting into decreased antibody production and suppressed immunity. Zinc is also an essential cofactor for thymulin which is known to modulate cytokine release and induce immune cell proliferation. Zinc deficiency is also found to impair an individual's epithelial barrier function, which may further depress the vaccine entry into the mucosal cells. Role of zinc in the prevention of diarrheal diseases and other infections in children is well documented. However, there are very few reports about its contribution to enhanced immunity by supporting body's natural defense system. Zinc insufficiency is widespread in socioeconomically deprived children in South Asia and the recent most national nutrition survey (2003) . Moreover, diarrhea is also very common in infants in Pakistan. Such diarrheal episodes can limit entry of attenuated polio virus into the mucosal cells, thereby, leading to inadequate immune response. Association between recent diarrheal history and increased vaccine failure in infants has been shown in a study from Brazil. The recent Lancet Nutrition series has also recommended regular zinc supplementation to address child undernutrition and stunting and underscored the need to treat diarrheal episodes with zinc to expedite recovery. Other recent studies of zinc supplementation in low birth weight infants in South Asia have also shown significant improvement in diarrheal disease burden and mortality. On the basis of these lines of evidence, it is possible that some of the cases of vaccine failure in this region could be a consequence of compromised immunity and, hence, diminished response to OPV. This could potentially be reversed by addressing such gross undernutrition and micronutrient deficiencies. It can thus be hypothesized that zinc supplementation at community scale would enhance the immune response in infants to OPV. In order to test this research question, the investigators propose to undertake 12-month randomized controlled trial among a cohort of Pakistani infants of 0-14 days of age. Such a trial would enable us to understand the synergistic role of zinc (if any) with OPV in enhancing immune response against polio and sero-conversion rates.
This study is designed to assess the immunogenicity and safety of PENTAXIM™ combined vaccine versus TETRAXIM™ vaccine to support registration of PENTAXIM™ in South Korea. Primary Objective: To demonstrate the non-inferiority in terms of seroprotection rates (Diphtheria, Tetanus, Polio types 1, 2 and 3, Polyribosyl Ribitol Phosphate [PRP]) and vaccine response rates to acellular Pertussis antigens of sanofi pasteur's PENTAXIM™ vaccine versus sanofi pasteur's TETRAXIM™ and Act (Haemophilus influenzae type b) HIB™ vaccines, one month after the three-dose primary vaccination.
The purpose of this study is to generate immunogenicity and safety data of an investigational hexavalent DTaP-IPV-Hep B-PRP-T vaccine compared to a control vaccine, Infanrix hexa™ when given along with Prevenar™ and Rotarix™ vaccines. Primary Objectives: - To demonstrate the equivalence of immunogenicity of 3 lots of DTaP-IPV-Hep B-PRP-T vaccine 1 month after a 3-dose primary series (2, 4 and 6 months) when given with Prevenar™ and Rotarix™, in terms of immunoresponses. - To demonstrate the non-inferiority of the hexavalent DTaP-IPV-Hep B-PRP-T vaccine to the licensed hexavalent Infanrix hexa vaccine when given with Prevenar™ and Rotarix™. Secondary Objectives: - To describe in each group the immunogenicity parameters for all antigens for each vaccine - To assess the safety profile in terms of solicited and unsolicited adverse events and serious adverse events in each group for each vaccine.
