Immunogenicity and Safety of PrepandrixTM in Korean Subjects Aged 18 to 60 Years Old
Immunogenicity and Safety of GSK Biologicals' (Pre-) Pandemic Influenza Vaccine PrepandrixTM in Korean Subjects Aged 18 to 60 Years Old

This study will evaluate the immunogenicity and the safety of PrepandrixTM in Korean subjects. A second group of subjects will receive FluarixTM vaccine as control.

Initially, 124 subjects were planned to be enrolled according to a 1:1 randomisation ratio. However, by mistake, the randomisation application was set up consistent with the vaccine supply ratio (2:1) rather than the treatment group randomization ratio (1:1). Subsequently, the protocol was amended to adjust the sample size and randomisation ratio for the study.

The study will enrol 126 subjects randomised 2:1. 84 subjects will receive Prepandrix™ and 42 subjects will receive Fluarix™.

  • Female subjects of non-childbearing potential may be enrolled in the study.
  • Female subjects of childbearing potential may be enrolled in the study, if the subject has practiced adequate contraception for 30 days prior to vaccination, has a negative pregnancy test on the day of vaccination, and has agreed to continue adequate contraception during the entire treatment period and for two months after completion of the vaccination series.

Exclusion Criteria:
