Exclusion Criteria

(1) History of hypersensitivity to any component of CAIV-T or inactivated influenza vaccine, including egg or egg protein (2) History of hypersensitivity to gentamicin (3) Any known immunosuppressive condition or immune deficiency disease (including HIV infection), or ongoing receipt of any immunosuppressive therapy; (4) History of Guillain-Barre syndrome; (5) Medically-diagnosed wheezing, bronchodilator use, or steroid use (systemic or inhaled) within the previous 42 days by parent report or chart review (e.g. children with recent persistent asthma are excluded), or history of severe asthma (6) Acute febrile (greater than 100.0 degrees Fahrenheit or greater than 37.8 degrees Celsius oral or equivalent) illness or acute respiratory illness, including cough or sore throat, within three days prior to enrollment; (7) Receipt of an investigational product within 30 days prior to enrollment or expected receipt during this study; (8) Use of aspirin or salicylate-containing products 30 days prior to enrollment or expected receipt during this study; (9) Use of anti-influenza medications (including amantadine, rimantadine, oseltamivir, and zanazmivir) within 14 days prior to enrollment or expected receipt during this study; (10) Receipt of any blood product within 90 days prior to vaccination or expected receipt during this study; (11) Administration of any live virus vaccine within 30 days prior to enrollment, or if receipt of another live virus vaccine is expected within 30 days of any study vaccination; (12) Administration of any inactivated vaccine within 14 days prior to enrollment or if receipt of another inactivated vaccine is expected within 14 days of any study vaccination; (13) Close contact who is severely immunocompromised (e.g. transplant recipient); (14) Family member or household contact who is an employee of the research center or otherwise involved with the conduct of the study; and (15) Any condition that, in the opinion of the investigator, might interfere with the interpretation or evaluationof the vaccines.

Note: An individual who initially is excluded from study participation based on one or more of the above time-limited criteria (e.g., acute febrile or acute respiratory illness, etc.) may be reconsidered for enrollment once the condition has resolved. Similarly, in cases of short term, reversible conditions, such as acute febrile or respiratory illness, Dose Two should be deferred until the child has recovered. Also, for children who experienced medically diagnosed wheezing, bronchodilator use, or steroid use (systemic or inhaled) within 42 days post Dose One, Dose Two should be deferred until a 42 day wheeze-free and bronchodilator/steroid-free period has elapsed. For children who have received another vaccine or anti-influenza medication in the intervening period, Dose Two should be deferred until the requisite period (14 days for inactivated vaccines and for anti-influenza medications, and 30 days for live vaccines) has elapsed. Subjects will not be permitted to receive their Dose Two medication if it is deferred past January 15, 2005.
