13 Clinical Trials for Various Conditions
The purpose of this study is to evaluate the immunogenicity and safety of GSK's trivalent MMR (Priorix®), comparing it to Merck"s MMR vaccine (M-M-R®II), which is approved for use in the US.
The goal of this study is to determine whether a computer-based intervention that delivers individually-tailored educational messages about the MMR vaccine increases MMR vaccine-hesitant parents' intentions to have their children vaccinated.
The purpose of this study is to evaluate the immunogenicity and safety of GSK Biologicals' trivalent MMR (Priorix), comparing it to Merck's MMR vaccine (M-M-R II), which is approved for use in the US in healthy children 12 to 15 months of age.
The purpose of this study is to evaluate end of shelf-life potency in terms of the immunogenicity and safety of GSK Biologicals' trivalent MMR vaccine, by comparing it to Merck \& Co., Inc.'s MMR vaccine, which is approved for use in the United States (US).
The purpose of this study is to compare two measles, mumps and rubella conjugate vaccines (manufactured by GSK and Merck and Company ) in terms of the immune response elicited and safety with a six month follow-up after first vaccination. Additionally, antibody persistence will be assessed one and two years after administration of MMR vaccine. The Protocol Posting has been updated following Protocol amendment 1 and 2, Oct 2009.
The North Carolina Immunization Branch will evaluate the use of the CDC program to improve adolescent vaccination practices (called Assessment, Feedback, Incentives, and eXchanges, or AFIX). This evaluation is the first of its kind in the nation and may have a profound impact on prevention. AFIX has four major components: 1) Assessment of a provider's current immunization practices and vaccination levels, 2) Feedback of the assessment results and strategies to improve coverage levels, 3) Incentives to improve coverage levels, and 4) eXchange of information and resources necessary to facilitate improvement. This program will evaluate the effectiveness of AFIX visits on affecting provider practices to increase adolescent (age 11-18) immunization. Visits include discussion of that practice's immunization rates and strategies for improving rates. The investigators will compare the changes, from baseline to 5 months, in immunization for practices receiving virtual visits (webinars), in-person visits, and no visits (control group). Thirty practices will be randomly assigned to each intervention type. The main outcomes of this study are practice-wide uptake rates of several adolescent vaccines (Tdap, HPV, and MCV4) as well as pre- and post-AFIX visit surveys focusing on recall tactics utilized by each practice. Data will be collected on practices with at least 200 adolescent patients (note: there is no patient-level data collected in this study).
The purpose of this study is to determine if 2 doses of Pneumococcal Conjugate Vaccine (PCV) followed by 1 dose of Pneumococcal Polysaccharide Vaccine (PPV) in HIV-infected children on anti-HIV therapy is helpful and safe in fighting pneumococcal infections in this group of children. This study will also look at the protection provided by childhood vaccination against measles, pertussis, and hepatitis B virus. Pneumococcal infections are the most common AIDS-related infection in HIV-infected children. PCV may help reduce the chances of HIV-infected children getting pneumococcal infections. This study will look at whether pneumococcal vaccines are safe and effective in HIV-infected children receiving HAART. It will look at whether HIV-infected children are protected by childhood vaccines received previously and if more doses are safe and improve protection.
To compare measles seroconversion rates (development of antibodies) at 13 months of age in HIV-infected and uninfected children on one of two immunization schedules: attenuated measles/mumps/rubella virus (M-M-R II) vaccine at 12 months versus attenuated measles vaccine (Attenuvax) at 6 months plus M-M-R II vaccine at 12 months. Recommendations for the age at vaccination should balance the need to minimize the risk of morbidity and mortality with the benefit of achieving the highest seroconversion rates. Immunizing a more intact immune system at an earlier stage of HIV infection may in turn achieve better and long-lasting measles protection. This study will help define a more effective measles vaccine regimen for children diagnosed with HIV infection and will provide greater insight into the functional status of the HIV-infected children's humoral immune system.
The main purpose of this study is to assess immune response and safety of various potencies of a measles, mumps, rubella, and varicella (MMRVNS) vaccines given to healthy children of 4 to 6 years of age.
The purpose of this study is to support licensure of GSK Biologicals' MMR vaccine (Priorix®) in the US by generating immunogenicity and safety data in contrast to the US standard of care, Merck's MMR vaccine (M-M-R®II), when given as a second dose to children four to six years of age.
The purpose of the study is to evaluate the immunogenicity and safety of Kinrix when co-administered with varicella (Varivax® \[varicella virus vaccine live\], Merck and Company) and (measles mumps rubella) MMR vaccines, compared to Kinrix co-administered with MMR vaccine alone. Both Kinrix and the second dose of Varivax are indicated in children 4-6 years of age, and there is great potential for the vaccines to be given concurrently. The aim of this trial is to demonstrate that co-administered Varivax does not negatively affect the immunogenicity or reactogenicity of Kinrix.
This is a study to evaluate the immune response and safety of GSK Biologicals 2-dose inactivated hepatitis A vaccine when administered with a measles/mumps/rubella vaccine and a varicella (chickenpox) vaccine in children as young as 15 months of age. The Protocol Posting has been updated in order to comply with the FDA Amendment Act, Sep 2007.
The purpose of this study is to see if the MMR and chickenpox vaccines work as well in premature infants as in children that were carried to full term. A group of children who were carried full-term will be matched for age, sex, and race and will be used for comparison.
