NCT00231907

Brief Summary

The purpose of this research is to compare the safety and ability to stimulate antibodies (part of the bodies proteins that fight infections) of two influenza (flu) vaccines given to children 12 to 35 months old. The two flu vaccines being compared are: trivalent inactivated influenza virus vaccine (TIV), a killed virus vaccine given as a shot licensed for use in children 6 months of age or older and live attenuated influenza vaccine (LAIV), a live (but weakened) virus vaccine licensed for children 5 years old and older given as a nose spray. The strains of the viruses have been weakened so that they do not cause typical influenza illness, but may allow the body to develop protection against the flu. LAIV vaccine is not licensed for children less than five years of age, therefore its use in this study is investigational. Participation is approximately 7 months in duration.

Outcome Measures

Primary Outcomes (2)

  • Assessment of post-dose 2 HAI (Hemagglutination Inhibition) antibodies to each of the 3 strains of influenza contained in the vaccine.

    Blood sample taken on day 0, 28 + 7, day 60 +/- 4.

  • Safety assessment of each of the vaccines in combination vaccine.

    Duration of study.

Secondary Outcomes (3)

  • Assessment of secretory IgA in nasal wash samples manifested after 1 or 2 doses of vaccine.

    Nasal wash samples will be colllected on Days 0, 30, and 60.

  • CMI

    Blood sample taken on Day 0, Day 28 + 7, Day 60 +/- 4.

  • Post-dose 1 HAI (Hemagglutination Inhibition) antibody titers and viral shedding.

    Day 3 to 5 post LAIV vaccination.

Interventions

FluMistBIOLOGICAL

Live attenuated influenza vaccine (LAIV) containing approximately 10\^7 TCID50 of each of the 3 influenza strains. 0.5 mL total dose volume administered intranasally via spray applicator (approximately 0.25 mL into each nostril). Administration of Flumist in children under 5 years of age is investigational.

  • Known or suspected immune deficiency diseases or immunosuppressed or have altered or compromised immune status as a consequence of treatment with immunosuppressive therapies.
  • Known close contact with a severely immunocompromised person, such as someone currently in isolation secondary to a bone marrow transplantation (LAIV recipients should avoid close contact with severely immunocompromised individuals for at least 7 days after vaccination).
