Active clinical trials for "Mumps"

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.

Mumps is an acute infectious respiratory disease caused by the mumps virus (MuV), which occurs mainly in children and adolescents. Its main clinical symptoms were parotid gland suppurative swelling and pain with fever. The pathological changes and harm caused by mumps was not only confined to the parotid gland, on the contrary, the social harm caused by serious complications cannot be ignored. As mumps is a vaccine-preventable infectious disease, vaccination is a fundamental strategy for controlling mumps. So far, there are 13 genotypes of MuV. Based on the analysis of molecular epidemiology, the main epidemic strain of MuV in China was the F genotype. The commonly used vaccine strains represented only a small number of known genotypes, e.g. Jeryl-Lynn (JL) and Rubini strains, which belong to type A, Urabe strain belongs to type B, and L-Zagreb strains belongs to type D. Virus seed of Live Attenuated Mumps Vaccine (Human diploid cell) developed by the institute was SP-A strain, which was the first separation and preparation of the attenuated mumps viruses in China. SP-A belongs to F genotype, which was the domestic epidemic genotype. In addition, the cell substrate prepared for vaccine was human diploid cell (KMB-17 strain), which is much safer to use. The results of phase I and II clinical trials showed that the vaccine possessed good immunogenicity and good antigenic cross-reactivity in infants (8-24 months old).

The purpose of this study is to evaluate the immunogenicity and safety of Recombinant Human Papillomavirus Bivalent (Types 16,18) Vaccine (Escherichia coli) （HPV）and Measles Mumps and Rubella Combined Vaccine, Live（MMR）

The preliminary test results showed that the vaccine possessed good immunogenicity and good antigenic cross-reactivity. The application of this vaccine will provide more effective means to prevent and control of mumps epidemic.

The purpose of this study is to investigate the immunity of persons fully vaccinated against measles, mumps and rubella and to examine the course of immunity after booster vaccination.

This is a study to assess the immunogenicity and safety of GlaxoSmithKline (GSK) Biologicals live attenuated measles-mumps-rubella-varicella vaccine given to healthy children in their second year of life.

The purpose of this study is to evaluate the immunogenicity and safety of a live attenuated mumps vaccine in healthy infants between 8 - 18 months old with a commercialized live attenuated mumps vaccine as the control vaccine.

Follow-up to evaluate the immunogenicity and safety of three production lots of GSK Biologicals' MMRV vaccine given as a two-dose schedule to healthy children in their second year of life, as compared to separate administration of GSK Biologicals' measles-mumps-rubella (MMR) vaccine (Priorix®) and varicella vaccine (Varilrix®) in Germany & Austria. Blood samples were collected at three time points during the follow-up period (Year 1, 2 & 3). No new subjects will be enrolled in these follow-up phases of the study.

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 purpose of this study is to evaluate the safety and immunogenicity of mumps vaccine in healthy infants aged 8-12months, compared with measles, mumps and rubella combined vaccine, live (MMRV).
