- Receipt of the 2010-2011 influenza vaccine
- Documented influenza infection during the 2010-2011 influenza season. Not excluded from the study, volunteers with prior upper respiratory infections during the 2010-2011 influenza illness.
Presence of co-morbidities or immunosuppressive states such as:
- Chronic medical problems including (but not limited to) insulin dependent diabetes, severe heart disease, severe lung disease, severe liver disease, severe kidney disease, auto immune diseases, severe gastrointestinal diseases, and uncontrolled hypertension.
- Alcohol or drug abuse and psychiatric conditions that in the opinion of the investigator would preclude compliance with the trial or interpretation of safety or endpoint data.
- Impaired immune function or chronic infections including (but not limited to) HIV, hepatitis B or C; organ transplant; cancer; current and/or expected receipt of chemotherapy, radiation therapy or any other cytotoxic or immunosuppressive therapy [i.e. more than 10 mg of prednisone given daily or on alternative days for 2 weeks or more in the past 3 months*; receipt of high-dose inhaled steroids is also an exclusion criteria (nasal and topical steroids are allowed.)], congenital immunodeficiency, anatomical or functional asplenia.
- Pregnancy or breast feeding
Conditions that could affect the safety of the volunteers such as:
- Severe reactions to prior vaccination with TIV, including anaphylaxis.
- History of Guillain Barré syndrome
- History of bleeding disorders
- Any allergy to any component of the vaccine including egg allergy.
- Volunteers with any acute illness, including any fever (> 100.4 F [> 38.0C], regardless of the route) within 3 days prior to study entry *.
Social, occupational, or any other condition that in the opinion of the investigator might interfere with compliance with the study and vaccine evaluation.
- Note:
An individual who initially is excluded from study participation based on one or more of the time-limited exclusion criteria (e.g., acute illness, receipt or expected receipt of live or inactivated vaccines ) may be reconsidered for enrollment once the condition has resolved as long as the subject continues to meet all other entry criteria.
Subjects receiving > 10 mg/day of prednisone or its equivalent daily or on alternate days for more than 2 weeks may enter the study after therapy has been discontinued for more than 3 months.
