Active clinical trials for "Rubella"

This is an open-label, randomized, 2-arm clinical trial in healthy infants in Bangladesh. The primary purpose of the study is to assess the immunogenicity of measles-rubella (MR) vaccine when delivered at 6 months. In addition, the study will establish the equality of MR vaccine seroconversion administered at 9 months following administration of an earlier MR vaccine dose at 6 months of age compared to MR vaccine dose administered at 9 months without previous MR vaccination. This study will also provide additional data on safety and tolerance of MR vaccine given at 6 months, and impact of maternal antibodies on immunogenicity of MR vaccine at 6 months. Primary objectives: To assess immunogenicity of MR vaccine at 6 months of age To assess immunogenicity of MR vaccine at 9 months of age among children without prior measles and rubella vaccination, compared with MR vaccine immunogenicity among those who had a prior MR vaccination at 6 months of age Secondary objectives To assess the frequency of adverse reactions following administration of MR vaccine at 6 months To compare the immunogenicity of the MR vaccine first dose administered at 6 months vs at 9 months. To assess the proportion of mothers with undetectable, detectable and protective levels of measles and rubella antibodies To determine the extent of variation in measles antibodies in women of child bearing age in a population with a long standing measles vaccination program To determine the extent of variation in rubella antibodies in women of child bearing age in a population where rubella vaccine have been recently introduced To determine if variation in antibody levels in infants at 6 months is predominately explained by variation in starting antibody levels in the mother in this population To estimate the half-life of decay of measles and rubella antibodies in infants

This study aims to provide evidence that co-administration of measles-mumps-rubella vaccine (MMR) and live attenuated SA 14-14-2 Japanese encephalitis vaccine (CD-JEV) does not adversely affect immunogenicity or safety.

The purpose of this study is to evaluate consistency in terms of the immune response to three different lots of GSK Biologicals' trivalent MMR vaccine manufactured to target potencies, and compare its immunogenicity to Merck & Co., Inc.'s MMR vaccine, which is approved for use in the United States (US).

This study is designed to compare the immunogenicity of Japanese encephalitis chimeric virus vaccine (JE-CV) and measles-mumps-rubella (MMR)vaccine when given together or when given at separate visits 6 weeks apart in toddlers aged 12 to 18 months. Primary objective: To demonstrate the non-inferiority of the antibody responses in terms of seroconversion of the concomitant administration of JE-CV and MMR compared to the antibody responses after the single administration of JE-CV and MMR vaccine. Secondary objectives: To describe the immune response to JE CV and MMR before and after one dose of JE CV and MMR vaccine, respectively. To describe the safety of a single dose of JE-CV and MMR vaccine (given separately at a 6-week interval and the safety of the concomitant administration of JE-CV and MMR vaccine in all subjects up to 6 months after last vaccination.

This study will compare three consistency lots of ProQuad to each other as well as to M-M-R II and Varivax, administered concomitantly at different injection sites, with respect to immunogenicity, safety, and tolerability.

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.

This is a modified single-blind, randomized, parallel-group, comparative, multicenter study to test Menactra vaccine in toddlers. Primary Objectives: To evaluate the antibody responses induced by Measles, Mumps, Rubella, and Varicella (MMRV) vaccine when administered alone or concomitantly with Menactra vaccine. To evaluate the antibody responses induced by Pneumococcal Conjugated Vaccine (PCV) when administered alone or concomitantly with Menactra vaccine. Observational Objectives: Safety - To describe the safety profile throughout the course of the study from Day 0 up to 6 months after the last study vaccination[s]) in subjects in the study groups. Immunogenicity: - To describe the antibody responses to meningococcal serogroups A, C, Y, and W-135, 30 days after the first and second Menactra vaccine administration in a subset of subjects in the first study group.

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.

This study will compare the immunogenicity and safety of the MeMuRu-OKA vaccine administered subcutaneously or using an alternative administration route.

An observer-blind study to evaluate GlaxoSmithKline Biologicals' live attenuated varicella vaccine and GlaxoSmithKline Biologicals' combined measles-mumps-rubella-varicella vaccine in the prevention of varicella disease in children. The Protocol Posting has been updated in order to comply with the FDA Amendment Act, Sep 2007.
