Intervention / Behandlung
Detaillierte Beschreibung
Colonies will be enrolled in September 2008.
Healthy Hutterite Children will be vaccinated in October, in each year of the study (2008, 2009, & 2010)
Influenza Surveillance phase will begin around December-January of each year.
- All study outcomes will be collected during the Surveillance phase of the study from Dec to June for 3 years.
- Outcomes will be collected when research nurses visit the colonies. A research nurse will visit enrolled colonies twice a week during the surveillance phase and review study diaries and obtain swabs from participants with symptoms of influenza.

Beschreibung
Group A:
Inclusion Criteria:
- Hutterites other than the healthy children who will be immunized. Although this category as a whole will be used to assess indirect benefit of the vaccine in the main analysis, Hutterites at high risk for influenza complications within this category will be assessed in a separate analysis. These are defined as anyone in one or more of the following groups:
- individuals aged ≥ 65 years
- children 23 months of age or less
anyone with ≥ 1 of the following conditions severe enough to require regular medical follow-up or hospital care:
- chronic cardiac or pulmonary disorders (including bronchopulmonary dysplasia, cystic fibrosis, and asthma)
- diabetes mellitus and other metabolic diseases
- cancer
- immunodeficiency
- immunosuppression (due to underlying disease and/or therapy)
- renal disease
- anemia
- hemoglobinopathy
- any condition that can compromise respiratory function or the handling of respiratory secretions or that can increase the risk of aspiration.
Exclusion Criteria:
- There are no exclusion criteria for this category of participants.
Group B:
Inclusion Criteria:
- Healthy children aged 36 months to 15 years who will be immunized as part of the intervention.
Exclusion Criteria:
- Anaphylactic reaction to a previous dose of influenza vaccine
- Anaphylactic reaction to hepatitis A vaccine
- Anaphylactic reaction to neomycin
- Known IgE-mediated hypersensitivity to eggs manifested as hives
- Swelling of the mouth and throat, difficulty in breathing, hypotension, or shock
- Guillain-Barré syndrome within eight weeks of a previous influenza vaccine.
