Phase: Phase 2
Study type: Interventional

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.

NCT ID: NCT03460002 Active, not recruiting - Children Clinical Trials

Vaccine Campaign Effects on General Hospital Admissions and Mortality Among Children

RE-CAMP
Start date: November 2016
Phase: Phase 4
Study type: Interventional

The world is set on eradicating measles and polio infections in the coming decade. Once both infections are under control, campaigns with measles and oral polio vaccines will be phased out. This might do more harm than good for child survival in low-income countries. Studies from the Bandim Health Project in Guinea-Bissau, and elsewhere, have revealed, that the live measles and oral polio vaccines have beneficial non-specific effects, i.e. effects on child morbidity and mortality unrelated to prevention of the targeted diseases. The campaigns are presumed to be most beneficial for children not reached by routine vaccination programs, as they are not already protected. However, studies show that prior routine or campaign vaccination may boost resistance against unrelated infections. If we phase out measles and oral polio campaigns after eradicating their target infections without considering the impact on child survival, the drastic decline in child mortality since 1990 could change direction. We will conduct the first cluster randomized controlled trial to evaluate the effect of measles and oral polio campaigns on general child morbidity and mortality via the Bandim Health Project. Bandim Health Project runs a Health and Demographic Surveillance System in Guinea-Bissau since 1978 and assesses child health interventions' real-life effects, via continuous registration of all interventions given to all children, and follow-up of individuals. We will conduct the trials in rural Guinea-Bissau monitoring all nine health regions. The hypotheses are: RECAMP-MV: Measles vaccination campaign in Guinea-Bissau reduce morbidity and mortality among children between 9 and 59 months of age by 80% during the subsequent 18 months in a context of limited measles infection. RECAMP-OPV: Oral polio vaccination campaigns in Guinea-Bissau reduce morbidity and mortality among children between 0 and 8 months of age by 25% during the subsequent 12 months in a context with no polio infection. Originally, the trials were meant to be implemented in 182 clusters, enrolling 21000 children. Following revised sample size calculations and discussions with the Data Safety and Monitoring Board, the number of clusters were increased to 222 and the planned number of enrolments increased from 21,000 to 28,000 (RECAMP-MV: 18000, RECAMP-OPV: 10000). To explore the hypothesis that at least part of the beneficial non-specific effects of OPV is driven by changes in the gut and/or respiratory microbiome, we will collect microbiome samples in a sub-group: A nasal swab and a rectal swab will be collected from 50 infants allocated to the intervention group, and 50 infants allocated to the control group. Two sample will be collected for each infant one when recruited for RECAMP-OPV and a second two months later.

NCT ID: NCT03330171 Active, not recruiting - Measles Clinical Trials

Safety and Immunogenicity of Measles Vaccine, Varicella Vaccine and Hepatitis-A Vaccine

MV/VV/Hep-AV
Start date: April 10, 2017
Phase: Phase 4
Study type: Interventional

This trial will evaluate the safety and immunogenicity of: i) measles vaccine (CAM-70) after primary dose at 6 months (MV1) and booster vaccination at 12 months (MV2); ii) a single dose of varicella vaccination at 18 months; and iii) a single dose of hepatitis-A vaccination at 18 months in HIV-exposed and HIV-unexposed South African children.

NCT ID: NCT02712203 Active, not recruiting - Measles Clinical Trials

MMR and MMRV Vaccines: Effect of Age at First Dose on Safety and Immunogenicity of the Measles Component.

Start date: July 2004
Phase: N/A
Study type: Observational

Healthy children who received two doses of GlaxoSmithKline (GSK) Biologicals' live attenuated measles-mumps-rubella vaccine (MMR) or measles-mumps-rubella-varicella vaccine (MMRV) in their second year of life.The purpose of this study is to assess the effect of the age at administration of the first dose on the reactogenicity and immunogenicity of the measles component of these vaccines. In addition, this study will evaluate if the effect of the age at first dose is modified by the type of vaccine administered.

NCT ID: NCT00932269 Active, not recruiting - Hepatitis B Clinical Trials

Seroimmunity 2007 and Sub Study of the Swedish Population Regarding Vaccine Preventable Disease

Sero 2007
Start date: March 2007
Phase: Phase 0
Study type: Observational

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.
