Primary Outcome Measures:
  • Immunogenicity [ Time Frame: 21 days post-vaccination ] [ Designated as safety issue: No ]
    That the immunogenicity of self-administered intradermal 2010/11 seasonal influenza vaccine (Intanza) is non-inferior to that of nurse administered intradermal 2010/11 seasonal influenza vaccine. Specifically, that ratio of increase in geometric mean titres between day 0 and day 21 post-vaccination are greater than 2/3 (i.e. GMT (IDS)/GMT (IDN) > 0.65).


Secondary Outcome Measures:
  • Reactogenicity [ Time Frame: 7 days post-vaccination ] [ Designated as safety issue: No ]
    The reactogenicity of self-administered intradermal 2010/11 seasonal influenza vaccine (Intanza) is not significantly greater than that of nurse administered intradermal 2010/11 seasonal influenza vaccine.

  • Observational [ Time Frame: at vaccination ] [ Designated as safety issue: No ]
    85% or more of healthy adults can self-administer Intanza successfully; that is, they are willing to self-administer vaccine and successfully administer it, as judged by observation by a trained nurse.

Arms Assigned Interventions
Active Comparator: Intanza - self-administered
Self-administered intradermal influenza vaccine
Biological: Intanza
0.1 mL of Intanza intradermally at visit # 1
Other Name: Influenza Vaccine (Split Virion, Inactivated)
Active Comparator: Intanza - nurse-administered
Nurse-administered intradermal influenza vaccine
Biological: Intanza
0.1 mL of Intanza intradermally at visit #1
Other Name: Influenza Vaccine (Split Virion, Inactivated)

Detailed Description:

Participants will be randomized at visit one to either receive self-administered or nurse-administered intradermal influenza vaccine (Intanza). A blood sample will be taken prior to vaccination and 21 days post-vaccination. Participants will record information in a memory aid for 7 days including daily temperatures, solicited, unsolicited and general reactions. They will be called on study Day 8 to collect this information. Participants will return 21-24 days later for follow-up serology and review of adverse events.

  Eligibility

Ages Eligible for Study:   18 Years to 60 Years
Genders Eligible for Study:   Both
Accepts Healthy Volunteers:   Yes
Criteria

Inclusion Criteria:

  • Medically stable persons between age of 18-60
  • Available during the trial period and for follow-up
  • Able to read, understand, and sign informed consent
  • Able to be contacted by telephone for follow-up of adverse events

Exclusion Criteria:

  • Use of experimental vaccines within the month prior to study entry, or expected use of experimental or licensed vaccines or blood/blood products during the duration of the study.
  • Receipt of immunoglobulin or other blood product within 3 months prior to enrollment
  • Receipt of other licensed vaccines within the preceding 4 weeks
  • History of a severe reaction following influenza vaccination
  • Use of cytotoxic therapy or biologic modifiers in the previous 2 years.
  • Plans to receive cytotoxic therapy during the study period.
  • Concurrent acute moderate to severe illness. (Vaccination will be deferred until recovery. Subjects with mild illnesses with fever ≤37.8ºC orally may be enrolled).

  • History of chronic lung, cardiac, renal or liver disease, which has required hospitalization in the last year.
  • Receipt of any high-dose daily systemic corticosteroids (inhaled steroids are acceptable) within two weeks of study entry. High dose is defined as a dose of 20 mg of prednisone daily or its equivalent. Topical steroids are allowed.
  • Failure to give written, informed consent
  • History of febrile illness (>37.8ºC orally) within the past 72 hours (immunization may be deferred).
  • Known allergy to eggs or other components of vaccine (i.e., thimerosal)
  • History of Guillain-Barré Syndrome (GBS)
