Brief Summary

In the 20th century, influenza pandemics occurred in 1918, 1957, and 1968, and were associated with significant morbidity and mortality. It is estimated that, in the United States alone, the next influenza pandemic could cause approximately 200,000 deaths and 750,000 hospitalizations. Thus, the development of a vaccine against potential influenza strains has become a priority. The purpose of this study is to determine the safety and immune response to an H6N1 influenza vaccine candidate.

Outcome Measures

Primary Outcomes (3)

  • Frequency of vaccine-related reactogenicity events and other adverse events

    Throughout study

  • Amount of vaccine virus shed by each participant

    Throughout study

  • Amount of serum and nasal wash antibody induced by the vaccine

    Throughout study

Secondary Outcomes (5)

  • Number of participants infected with the H6N1 Teal HK 97/AA ca recombinant vaccine

    Throughout study

  • Phenotypic stability of vaccine virus shed

    Throughout study

  • Determine whether immunogenicity is enhanced by a second dose of vaccine, and whether the first dose of vaccine restricts replication of the second dose

    Throughout study

  • T-cell mediated and innate immune responses against the H6N1 Teal HK 97/AA ca recombinant vaccine

    Throughout study

  • Development of serum bank so that the capacity of the H6N1 Teal HK 97/AA ca recombinant vaccine to elicit HA1 and neutralizing antibodies to future H6 influenza viruses can be tested

    Throughout study

Study Arms (1)

1

EXPERIMENTAL

Participants will receive 2 doses of vaccine 4 to 8 weeks (28-62 days) apart

Biological: H6N1 Teal HK 97/AA ca recombinant vaccine

Interventions

Approximately 0.2 ml of 10\^7 TCID50 doses of vaccine administered intranasally
