Eligibility Criteria

Age2 Years - 49 Years
Sexall
Healthy VolunteersYes
Age GroupsChild (0-17), Adult (18-64)

You may qualify if:

  • Otherwise healthy, ambulatory 2-8 years old (Group A) or 18-49 years old (Group B).
  • Willing to complete the informed consent process (including assent for minors 7 years old and above).
  • Availability for follow-up for the planned duration of the study at least 28 days after immunization.

You may not qualify if:

  • Prior off-study vaccination with the current 2012-2013 seasonal TIV or LAIV.
  • Allergy to egg or egg products, or to vaccine components, including gentamicin, gelatin, arginine or MSG (LAIV)
  • 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 the first study visit and on the day of vaccination.
  • 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)
  • Participants in close contact with anyone who has a severely weakened immune system should not receive LAIV
  • 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.
  • History of blood dyscrasias, renal disease, or hemoglobinopathies requiring regular medical follow up or hospitalization during the preceding year
