Filter by:The primary objective is to measure the effect of host human genetics on the resulting immunological responses and long-term protection following rotavirus immunization of a study population of infants in Ho Chi Minh City, Vietnam. The secondary objectives are to assess the temporal immunological responses following rotavirus vaccination, and to investigate the role of maternally derived antibodies, and other factors that could potentially affect immunological responses following rotavirus vaccination. Also to assess infecting rotavirus genotypes in the vaccine failure cases.
This is a nested case-control study within an ongoing rotavirus vaccine immunogenicity trial in Karachi, Pakistan. The primary study aim is to compare the fecal microbiota composition and diversity of infants who do (control) and do not (case) demonstrate immune seroconversion to rotavirus vaccination. The infants will be matched for vaccination dose, age and breast-feeding practices.
The purpose of this study is to evaluate the immunogenicity and safety of the diphtheria, tetanus, pertussis and inactivated poliovirus (DPT-IPV) vaccine Squarekids administered with or without the GSK Biologicals' liquid Rotarix (HRV) vaccine, in healthy Japanese infants aged 6 - 12 weeks. GSK Biologicals' liquid HRV vaccine Rotarix is licensed in Japan since 2011. Although the concomitant administration of GSK Biologicals' DTP-IPV vaccine has been evaluated during the clinical development of the HRV vaccine, the vaccine differed in composition and route of administration from the DPT-IPV vaccine Squarekids manufactured in Japan. Hence, as requested by the Japanese regulatory authorities, this post-licensure study will evaluate the immunogenicity of the DPT-IPV vaccine manufactured in Japan when co-administered with the liquid HRV vaccine
Acute gastroenteritis is a common cause of hospitalization in children with significant socioeconomic burden on the health community, we will follow in this observational and analytical study the admitted cases of acute gastroenteritis to the pediatric floor at the Sheikh Ragheb Harb Hospital over a period of summer time to determine the causes, etiologies and epidemiology of Age in a community hospital.
Nowadays these are some vaccines being vaccinated simultaneously, and a doubt is aroused if the safety and immunogenicity are same between inoculating several vaccines simultaneously and inoculating individually. So we carry out this study. The purpose of this study is to evaluate the difference of safety and immunogenicity on vaccinating rotavirus vaccine simultaneously with measles-rubella vaccine(MR) or measles-mumps-rubella vaccine(MMR) compared to vaccinating rotavirus vaccine, MR or MMR individually.
The purpose of this study is to evaluate the immunogenicity, reactogenicity and safety of GSK Biologicals' HRV liquid vaccine compared to GSK Biologicals' HRV lyophilized vaccine when administered as a two-dose primary vaccination in healthy infants aged 6-10 weeks at dose one, with no previous history of rotavirus illness or vaccination. While the lyophilized formulation of the HRV vaccine was licensed in India in February 2008, this study is conducted to generate additional clinical data for the liquid formulation of the HRV vaccine in India, as recommended by New Drug Advisory Committee on Vaccines (NDAC-Vaccines) of Drug Controller General of India (DCGI).
To determine the effectiveness of rotavirus vaccines, active surveillance will be conducted at two sites, Cincinnati Children's Hospital Medical Center (CCHMC) in Cincinnati, Ohio and the Medical University of South Carolina (MUSC) in Charleston, South Carolina. Children born on or after April 1, 2006 presenting to CCHMC as an inpatient or for a short-stay or Emergency Department (ED) visit with acute gastroenteritis (AGE) and/or fever will be approached for enrollment. Children will be eligible if they have vomiting and/or diarrhea less than or equal to 10 days duration. Data including demographic information, illness characteristics and socio-economic status will be collected from each patient. A sample of the patient's stool will be collected within 14 days of the onset of symptoms. Stool specimens will be tested for rotavirus antigen by Rotaclone at CCHMC. All rotavirus positive stool specimens will be typed for common G and P serotypes. Using the children identified with rotavirus as our cases and the children who were rotavirus negative as our controls, we will conduct a case control study to assess the effectiveness of rotavirus vaccines, in particular Rotarix.
This is a Phase I clinical trial including 2 parts to evaluate the safety and immune response to RotaTeq™ /placebo in subjects of 65 to 80 years of age. In Part I, approximately 60 subjects in US will be randomly assigned to 1 of 2 treatment groups receiving 3 doses of RotaTeq™ or placebo. In Part II, approximately 200 subjects internationally will be randomly assigned to 1 of 3 treatment groups. Part II will start after Part I data analysis is reviewed and approved by the FDA/CBER, the Safety Evaluation Committee (SEC) and other regulatory agencies. Duration for the entire study will be approximately 4 years. Note: As the result of a business decision by the Sponsor, the study did not proceed with Part II. Therefore, this report includes the results for Part I only.
Rotavirus is the most common cause of severe infantile diarrhoea disease in infants and young children below five years worldwide. It is associated with high cases of morbidity and mortality and it is estimated that up to 600,000 deaths in young children occur annually in the less developed countries and approximately 150,000-200,000 deaths occur in Africa alone. In Kenya, most rotavirus surveillance work has been done in Nairobi (an urban setting). Other parts e.g eastern Kenya, limited data is available and hence the prevalence and burden of rotavirus disease is under-estimated. We therefore hypothesize that rotavirus prevalence is high in Meru,Maua (a rural setting)and hence we designed a study to evaluate this. This is a prospective study to determine, the rotavirus disease burden and epidemiology in infants and children with severe diarrhoea hospitalized in three sentinel hospital in the eastern part of Kenya (Maua Methodist hospital) will be carried out during the period January 2009 to December 2010. Faecal samples will be collected from infants and children admitted with acute diarrhoea and screened first for the presence of human serotype A rotavirus antigen using commercially available enzyme linked immunosorbent assay kit (ELISA). The positive samples will be evaluated by sodium dodecyl polyacrylamide gel electrophoresis (SDS-PAGE) to determine the electropherotypes and genotyped using reverse transcriptase polymerase chain reaction (RT-PCR) on VP7 and VP4 gene. These data/ results generated from this project will add crucial information on the rotavirus strains circulating in the eastern part of Kenya.
The purpose of the study is to evaluate whether V260 is effective and well tolerated in Japanese healthy infants.
