This trial is active, not recruiting.
|Treatment||mmr vaccine / mmrv vaccine|
|Sponsor||Centre Hospitalier Universitaire de Québec, CHU de Québec|
|Start date||July 2004|
|End date||July 2010|
|Trial size||5808 participants|
|Trial identifier||NCT02712203, 200783|
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.
Short term seropositivity rates & anti-measles antibody titers after vaccination with MMR or MMRV
time frame: At day 42 after administration of a dose of MMR or MMRV vaccine
Injection site reaction
time frame: Days 0-3 after vaccination
time frame: Days 0 - 42 after administration of a dose of MMR or MMRV vaccine
Long term seropositivity rates and anti-measles antibody titers after vaccination with MMR or MMRV
time frame: 2 and 3 years after vaccination with 2 doses of MMR or MMRV vaccines
Male or female participants from 11 months up to 22 months old.
- Healthy male or female subject between 11 to 22 months at the time of first vaccination.
- Written informed consent obtained from the parent/guardian of the subject.
- History of previous measles, mumps, rubella and/or varicella vaccination or disease or known exposure to any of these diseases within 30 days prior to the inclusion in the study.
- Any confirmed or suspected immunosuppressive or immunodeficient condition, included the chronic administration (defined as more than 14 days) of immune-suppressants or other immune-modifying drugs within six months prior to the firs vaccine dose.
- History of any neurologic disorders or seizures.
- History of allergic diseases or reactions likely to be exacerbated by any component of the vaccines.
- Planned administration of a vaccine not foreseen by the study protocol from 30 days prior to each vaccination until 42-56 days after each vaccination
