Filter by:A study team with extensive experience in immunization delivery research will evaluate the effectiveness of vaccination reminder/recall systems for adolescent patients in five types of clinical settings including: urban pediatric, urban family medicine and rural family medicine practices, public pediatric clinics, and school-based health centers. Randomized controlled trials of reminder/recall for adolescents will be conducted at each type of site, with randomization at the level of the patient.
The purpose of this observer blinded study is to provide information on vaccine immunogenicity and reactogenicity in comparison with the US standard of care (ProQuad®) when administered with Hepatitis A vaccine and Pneumococcal vaccine.
The aim of this study is to evaluate a modified formulation of GSK Biologicals' live attenuated varicella vaccine. In vivo pre-clinical data show this change has no negative impact on vaccine safety. This present study is undertaken to rule out any negative impact on the immunogenicity and safety of GSK Biologicals' live attenuated varicella virus vaccine.
The primary study objectives are: - To demonstrate that a 2-dose regimen of ProQuad® manufactured with recombinant Human Albumin (rHA) administered at a 3-month interval to healthy children of 11 months of age at the time of Dose 1 is as immunogenic as in healthy children of 12 months of age at the time of Dose 1. - To demonstrate that a 2-dose regimen of ProQuad® rHA administered at a 3-month interval to healthy children of 9 months of age at the time of Dose 1 is as immunogenic as in healthy children of 12 months of age at the time of Dose 1. - To demonstrate that a 2-dose regimen of ProQuad® rHA administered at a 3-month interval to healthy children of 11 months of age and 9 months of age at the time of Dose 1 is well-tolerated compared to children of 12 months of age at the time of Dose 1. The first primary hypothesis was that a 2-dose regimen of ProQuad® rHA, administered at a 3-month interval to children of 11 months of age, would be non-inferior in terms of antibody response rates to measles, mumps, rubella, and varicella at Day 42 following Dose 2, to the same regimen in children of 12 months of age at the time of Dose 1. If the first primary hypothesis was demonstrated, the second primary hypothesis was that a 2-dose regimen of ProQuad® rHA, administered at a 3-month interval to children of 9 months of age, would be non-inferior in terms of antibody response rates to measles, mumps, rubella, and varicella at Day 42 following Dose 2, to the same regimen in children of 12 months of age at the time of Dose 1. The secondary study objectives are: - To describe the antibody titres to measles, mumps, rubella and varicella at Day 42 following Dose 1 and Dose 2 of ProQuad® rHA administered to healthy children from 9 months of age. - To evaluate the safety profile of Dose 1 and Dose 2 of ProQuad® rHA administered to healthy children from 9 months of age.
Primary objective: To describe the safety profile of a second dose of ProQuad® manufactured with recombinant human albumin (rHA) when administered to children in their second year of life. Secondary objectives: To describe the safety profile of a first dose of ProQuad® manufactured with rHA when administered to children in their second year of life.
To observe the safety and tolerability of the administration of VARIVAX in varicella history negative Indian children 12 months to 12 years of age.
This clinical trial will evaluate the safety of two injections of Menactra® Vaccine in subjects at 9 months and at 12 months of age when the second dose is given concomitantly with other pediatric vaccines routinely administered in the US. Safety Objective: To describe the safety profile of two doses of Menactra® Vaccine.
Primary objective: To describe the safety profile of a refrigerator-stable formulation of VARIVAX® as a first single dose injection in 12 to 15 month-old infants in the 42-day follow-up period post-vaccination. Secondary objectives: NA
Primary objective: To compare if, when given concomitantly with VARIVAX® by the same route at 12-18 months of age using separate injection sites, a single dose of M-M-RTMII administered by IM route is as immunogenic as a single dose of M-M-RTMII administered by SC route in terms of response rates to measles, mumps and rubella at 42 days following the vaccination. AND/OR To compare if, when given concomitantly with M-M-RTMII by the same route at 12-18 months of age using separate injection sites, a single dose of VARIVAX® administered by IM route is as immunogenic as a single dose of VARIVAX® administered by SC route in terms of response rate to varicella at 42 days following the vaccination Secondary objectives: - To summarise the antibody titres to measles, mumps, rubella and varicella at 42 days following the vaccination in children immunised with M-M-R™II and VARIVAX® administered concomitantly at two separate injection sites by the same route IM or SC, - To evaluate the safety profiles of M-M-R™II and VARIVAX® administered concomitantly at two separate injection sites by the same route IM or SC.
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.
