  Purpose
The study is designed to assess the immunogenicity and safety of one booster vaccination with 45 μg of a recombinant H5N1 influenza (A/Indonesia/05/2005) HA vaccine in healthy young adults, previously primed with a two-vaccination of 3 different doses of a recombinant H5N1 influenza (A/Vietnam/1203/2004) HA vaccine in a priming study (JPIP501-01a, NCT00980447).

Primary Outcome Measures:
  • Percentage of subjects achieving seroconversion 21 days after a booster vaccination, as measured by hemagglutination inhibition (HI) assay against H5N1 influenza viruses (A/Indonesia/05/2005 & A/Vietnam/1203/2004) [ Time Frame: Day 21 ]

Secondary Outcome Measures:
  • Percentage of subjects achieving seroprotection or significant increase in antibody titer on each blood sampling days after a booster vaccination, as measured by HI and microneutralization assays against the H5N1 influenza viruses [ Time Frame: Days 7, 21 ]
  • Incidence of adverse events including solicited local or systemic reactions until 21 days after a booster vaccination [ Time Frame: 21 days ]

Estimated Enrollment: 87
