Filter by:The purpose of this study is to determine the efficacy of the liquid formulation of CAIVT against culture confirmed influenza illness in healthy children aged at least 6 months and less than 36 months, attending day care centers in Europe. In addition, the trial provides the opportunity to investigate the effect of CAIV-T on acute otitis media, on healthcare resource utilization and economic resources.
The primary objective of this study was to perform a variety of immunological assays on blood, serum, nasal wash samples, and cells obtained from healthy adult subjects for the purpose of developing assays for application in the further investigation of immune responses generated by influenza virus vaccine, trivalent, types A and B, live, cold-adapted (liquid CAIV-T).
To measure the effectiveness of influenza vaccination in school children by comparing, between target(i.e., children are offered FluMist) and control (i.e., children are not offered FluMist) school families.
To perform a variety of assays on blood, serum, nasal wash samples and cells obtained from healthy adult subjects for the purposes of developing assays for application in the further investigation of immune responses generated by influenza virus vaccine, trivalent, types A and B, live, cold-adapted (liquid CAIV-T; Wyeth Lederle Vaccines, Marietta, PA).
A safety study to compare, over a 7 day period, the fever rates following one dose of either Influenza Virus Vaccine or placebo administered outside the influenza season to healthy children and adolescents aged 6 to less than 18 years.
- The primary objective of the study was to determine if intranasally administered influenza virus vaccine, CAIV-T), when administered concomitantly with a subcutaneously administered combination live, attenuated mumps, measles, and rubella (MMR) virus vaccine to children interferes with the immune responses.
The purpose of this clinical study was to evaluate immune responses measuring antibodies in serum and secretions and cellular immune responses generated by CAIV-T vaccine in healthy adults aged 18 years and older as a means to develop assays for application in investigating potential immunological correlates of protection and/or establishing assays to measure vaccine take.
- To describe the proportion of individuals 5-49 years of age who shed vaccine strain viruses. - To describe the duration of shedding of vaccine viruses in individuals 5-49 years of age. - To describe the genotypic and phenotypic stability of shed vaccine viruses. - To describe the immune responses of FluMist in individuals 5-49 years of age. - To describe the safety of FluMist in individuals 5-49 years of age in relation to shedding and the immune response
This study is to assess the safety of a bivalent vaccine of two new 6:2 influenza virus reassortants in healthy adults prior to the release of the trivalent vaccine (FluMist) containing them.
This protocol is to compare the immune response of different influenza vaccines given by two different routes of administration in healthy adults ages 18 to 64 years.
