Primary Outcomes (1)
Number of Participants Who Received Influenza Vaccine
Day 0 to 28
Secondary Outcomes (1)
Number of Participants With Related Adverse Events
Day 0 to 28 post-immunization
Other Outcomes (1)

Day 0 to 28
Study Arms (3)
Group A: 8-17 yo identical twins
OTHERGroup A: 8-17 year-old identical twin pairs randomly assigned to Fluzone (trivalent, inactivated influenza vaccine (TIV)) or FluMist (live, attenuated influenza vaccine (LAIV)) within the pair
Group B: 8-30 yo non-twin
OTHERGroup B: 8-30 years old non-twin individuals randomly assigned to Fluzone (trivalent, inactivated influenza vaccine (TIV)) or FluMist (live, attenuated influenza vaccine (LAIV))
Group C: 70-100 yo non-twin
OTHERGroup C: 70-100 years old non-twin elderly adults given Fluzone (trivalent, inactivated influenza vaccine (TIV))

Eligibility Criteria
You may qualify if:
- Healthy, ambulatory 8-17 year old identical twins, 8-30 year old non-twins, or 70-100 year old elderly non-twin adults.
- Willing to complete the informed consent process.
- Availability for follow-up for the planned duration of the study at least 28 days after immunization.
- Acceptable medical history by medical history and vital signs.
You may not qualify if:
- Prior vaccination with seasonal TIV or LAIV or H1N1.
- Prior off-study vaccination with the current seasonal TIV or LAIV
- Allergy to egg or egg products, or to vaccine components
- Life-threatening reactions to previous influenza vaccinations
- Asthma or history of wheezing
- Active systemic or serious concurrent illness, including febrile illness on the day of vaccination
- History of immunodeficiency (including HIV infection)
- Known or suspected impairment of immunologic function, including, but not limited to, clinically significant liver disease, diabetes mellitus treated with insulin, moderate to severe renal disease, or any other chronic disorder which, in the opinion of the investigator, might jeopardize volunteer safety or compliance with the protocol.
- Blood pressure \>150 systolic or \>95 diastolic at first study visit
- Hospitalization in the past year for congestive heart failure or emphysema.
- Chronic Hepatitis B or C.
- Recent or current use of immunosuppressive medication, including systemic glucocorticoids (corticosteroid nasal sprays and topical steroids are permissible in all groups; inhaled steroid use is not permissible except for non-LAIV Group C only). Use of oral steroids (\<20mg prednisone-equivalent/day) may be acceptable for volunteers 70-100 yrs of age after review by the investigator.
- Participants in close contact with anyone who has a severely weakened immune system should not receive LAIV (Groups A and B only)
- Malignancy, other than squamous cell or basal cell skin cancer (includes solid tumors such as breast cancer or prostate cancer with recurrence in the past year, and any hematologic cancer such as leukemia).
- Autoimmune disease (including rheumatoid arthritis treated with immunosuppressive medication such as Plaquenil, methotrexate, prednisone, Enbrel) which, in the opinion of the investigator, might jeopardize volunteer safety or compliance with the protocol.
