The Human Mucosal Immune Responses to Influenza Virus (SLVP026)
Trial ID or NCT#
NCT03023553
Status
NOT RECRUITING
Purpose
This study will examine the immune responses to the seasonal influenza vaccine in single cells of the nasal passages when compared with cells in circulating blood.
Official Title
The Human Mucosal Immune Responses to Influenza Virus: A Systems Biology Approach. Innate Immune Responses to Influenza Virus in Single Human Nasal Epithelial Cells
Eligibility Criteria
Ages Eligible for Study: 18 Years to 30 Years
Sexes Eligible for Study: ALL
Accepts Healthy Volunteers: Yes
Inclusion Criteria:
- 1. Otherwise healthy, ambulatory adult between the ages of 18-30 years2. Willing to complete the informed consent process.3. Availability for follow-up at Day 2 (LAIV Group only)4. Acceptable medical history by review of inclusion/exclusion criteria and vital signs.
Exclusion Criteria:
- 1. Prior off-study vaccination with the current 2012-2013 seasonal TIV or LAIV2. Allergy to egg or egg products, or to vaccine components, including thimerosal (TIV multidose vials only), or gentamicin, gelatin, arginine or MSG (for LAIV only).3. Life-threatening reactions to previous influenza vaccinations4. Asthma or history of wheezing (except for controls in the study who will be assigned to receive TIV).5. Active systemic or serious concurrent illness, including febrile illness on the day of vaccination6. History of immunodeficiency (including HIV infection)7. 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.8. Blood pressure \>150 systolic or \>95 diastolic at first study visit9. Hospitalization in the past year for congestive heart failure or emphysema.10. Chronic Hepatitis B or C.11. Recent or current use of immunosuppressive medication, including systemic glucocorticoids. Corticosteroid nasal sprays for allergies and topical steroids are permissible. Inhaled steroids for conditions such as asthma are not permissible for volunteers in the LAIV group.12. Participants in close contact with anyone who has a severely weakened immune system should not receive LAIV (LAIV Group only).13. 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).14. 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.15. History of blood dyscrasias, renal disease, or hemoglobinopathies requiring regular medical follow up or hospitalization during the preceding year16. Use of any anti-coagulation medication such as Coumadin or Lovenox, or anti-platelet agents such as aspirin (except up to 325 mg. aspirin per day), Plavix, or Aggrenox must be reviewed by investigator to determine if this would affect the volunteer's safety..17. Receipt of blood or blood products within the past 6 months of planned used during the study.18. Medical or psychiatric condition or occupational responsibilities that preclude participant compliance with the protocol19. Inactivated vaccine 14 days prior to vaccination or planned non-study vaccination prior to completion of the last study visit.20. Live, attenuated vaccine within 60 days of vaccination or planned non-study vaccination prior to completion of the last study visit.21. History of Guillain-Barré Syndrome22. Pregnant or lactating woman23. Use of investigational agents within 30 days prior to enrollment or planned use of investigational agents prior to completion of study visits.24. Donation of the equivalent of a unit of blood within 6 weeks prior to enrollment or planned donation prior to completion of the last visit.25. Any condition which, in the opinion of the investigator, might interfere with volunteer safety, study objectives or the ability of the participant to understand or comply with the study protocol.
