Active clinical trials for "Rubella"

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.

This study will collect data on the safety of the MMRV vaccine (Priorix-Tetra™) used in routine practice in children aged 12 months to 12 years living in the Philippines.

On a previous study conducted in Brazil. The MMR vaccine from 2 different producers had a mumps seroconversion much lower (71%) than the expected 95%, according to the package insert. This could indicate that a substantial proportion of children was not protected after MMR dose.

The purpose of this study is to determine the reasons why multiparous women (women who are pregnant and have been pregnant before) might still be susceptible to rubella.

This is a randomized cross-sectional study of the Swedish population. Blood samples will be collected from a subpopulation in order to estimate the age specific sero-prevalence of the Swedish population for diseases included in the National Immunization Program (NIP), and to affirm the population's protection against polio. To be able to recommend complementary immunizations to immigrated children, a sub study focusing on foreign born teenagers will also be done and compared to children of the same age born in Sweden.
