NCT00516035

Brief Summary

Over the past decade, avian influenza (AI) has become a major health concern. The development of safe and effective vaccines against avian strains infecting people is important. The purpose of this study is to determine the safety of and immune response to a new AI vaccine in healthy adults against the H7N3 strain of avian influenza.

Outcome Measures

Primary Outcomes (3)

  • Safety, defined as the frequency of vaccine-related reactogenicity events that occur during the acute monitoring (inpatient) phase of the study

    Daily for 9 days after vaccination

  • Immunogenicity, determined by anti-H7N3 antibody titer

    Before the first vaccination, 28 days after the first vaccination but before the second vaccination, and 28 days after the second vaccination

  • Quantifying the amount of vaccine virus shed by each recipient; and determining the amount of serum and nasal wash antibody induced by the vaccine

    Daily for 9 days after vaccination

Secondary Outcomes (5)

  • To determine the number of vaccinees infected with the vaccine virus

    Daily for 8 days after each vaccination

  • To determine the phenotypic stability of the vaccine virus

    Throughout study

  • To determine whether immunogenicity is enhanced by a second dose of vaccine

    At study completion

  • To evaluate T-cell mediated and innate immune responses against the vaccine virus

    Throughout study

  • To develop a serum bank to evaluate future H7 influenza vaccines

    Throughout study
