Active clinical trials for "Rubella"

The purpose of this study is to determine the mumps virus strength at the end of shelf-life (expiration date) of an approved vaccine.

The aim of the research is to study humoral and cellular immunity in pregnant women for who the level of rubella virus antibodies is weakly positive, equivocal or negative with the usual laboratory technique.

The study was conducted to determine if ProQuad may be used in place of the second dose of M-M-R II routinely given to children 4 to 6 years old who were previously immunized with M-M-R II and Varivax.

A Study comparing three different doses of ProQuad to concomitant administration of M-M-R II and PUVV (Process Upgrade Varicella Vaccine) vaccines.

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.

Background: It is well established that the presence of bacteria in the intestine has a profound influence on health. Probiotics, ("beneficial bacteria") have shown ameliorating effects on various infectious diseases. The influence of probiotics on several immune-mediated conditions has also been investigated, among them, atopic dermatitis ("Asthma of the skin"), and milk allergy. The precise mechanism of action of probiotics is not fully understood. Several animal and human studies have shown the probiotic bacteria to influence the immune system. The aim of the present study is to evaluate whether supplementing the diet with oral probiotics affects the immune response of children following routine vaccination against 4 common childhood viral diseases: Mumps, Measles, Rubella and Varicella. Objective(s) and Hypothesis(es): Hypothesis: Administration of probiotics will increase the amount of antibodies produced following vaccination for Measles, Mumps, Rubella and Varicella, by over 15%. Objectives: To determine whether administration of probiotics during infancy influences antibody levels following the routine childhood vaccinations. To determine whether administration of probiotics during infancy influences the rate of adverse effects following the routine childhood vaccinations. Potential Impact: Vaccines, alongside with the discovery of Penicillin, have been cited as the great public health successes of the 20th century. However, even in countries with maximal childhood immunization coverage, the protective effect is not optimal. For example, only 70% to 90% of children immunized against chickenpox are actually protected against the disease. If we succeed in raising these numbers, even by a single percent, it will have a huge impact on society.

This research is designed to address the question, "Does the relative deficit in vaccine immunogenicity in extremely premature infants persist beyond the first 6 months of life?" We propose to measure the immunogenicity of varicella and mumps-measles-rubella vaccines in relatively healthy, 12-to-15 month-old children born at <29 weeks gestation, when compared to full-term infants, as measured by the relevant viral serologies.

This study will lay the foundation for determining the underlying reasons for lack of immunity to mumps that led to the 2006 mumps outbreak on college campuses in the Mid West, and it will assess the potential for similar outbreaks of measles and rubella. A total of 70 to 80 college students (age 18 to 22) on the Emory campus (or nearby college campuses or the community) will be assessed for antibodies to measles, mumps or rubella by drawing a one-time blood sample. Their medical records will be verified for documentation of immunization with MMR vaccine prior to enrollment in the study. If a study volunteer is found to not have MMR immunity, they will be offered an MMR-II vaccine. For this group, additional blood specimens will be obtained.

The purpose of this survey is to assess the safety of freeze-dried live attenuated measles and rubella combined vaccine (Schwarz FF-8 strain/TO-336 strain) (freeze-dried live attenuated measles and rubella combined vaccine "Takeda") in terms of the occurrence of unknown/known adverse drug reactions and factors that may influence the safety of vaccinees after the second vaccination.
