Official title
A Randomized, Double-blinded, Placebo Controlled Phase III Study to Evaluate the Immunogenicity and Safety of GSK Bio Influenza Vaccine (Fluarix) Administered Intramuscularly in Healthy Adults
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
The purpose of this study is to test the immune response caused by investigational Fluarix vaccine in healthy people aged between 18-64 years in the U.S.A. Up to 1050 volunteers at 4 centers will receive Fluarix or Placebo (saline), and their responses will then be compared. Subjects will be placed by age into 2 groups (18 to 49 years old and 50 to 64 years old), then randomly assigned to receive a dose of Fluarix or Placebo by injection into a muscle. There will be 2 phases in this study: (1) the active study phase (2 visits) for all subjects; and (2) the cross-over phase, only for subjects enrolled in the placebo group who accept to receive Fluarix. Blood samples will be obtained in order to measure immune response to the vaccine. On the day of vaccination, volunteers will receive a diary card to record information on symptoms experienced during the next 3 days. Subject participation in either group will be up to 2 months.
