Trial Title: Tissue-specific Responses to Influenza Immunization and Their Relation to Blood Biomarkers (SLVP032)

Study Design Characteristics:
- Allocation: NON_RANDOMIZED
- Intervention Model: SEQUENTIAL
- Observational Model: None
- Primary Purpose: BASIC_SCIENCE
- Time Perspective: None
- Masking: NONE
- Phase: PHASE4
- Number of Arms: 2.0

Eligibility Criteria:
Inclusion Criteria:~1. Generally healthy 18-49 year old male and female patients undergoing tonsillectomy for obstructive sleep apnea.~2. Willing to complete the informed consent process~3. Availability for follow-up for the planned duration of the study~4. Acceptable medical history by review of inclusion/exclusion criteria~Exclusion Criteria:~1. Prior off-study vaccination with seasonal influenza vaccine within three months of study vaccination~2. Life-threatening reactions to previous influenza vaccinations~3. Asthma (contraindication for receipt of LAIV4) for study volunteers; not a contraindication for enrolling as a pilot phase volunteer receiving IIV4.~4. Allergy to egg or egg products or to vaccine components (including gentamicin, gelatin, arginine or MSG for participants receiving LAIV4).~5. Active systemic or serious concurrent illness, including febrile illness on the day of vaccination~6. History of immunodeficiency (including HIV infection)~7. Known or suspected impairment of immunologic function; may include significant liver disease, diabetes mellitus treated with insulin or moderate to severe renal disease~8. Hospitalization in the past year for congestive heart failure or emphysema.~9. Chronic Hepatitis B or C.~10. Recent or current use of immunosuppressive medication, including systemic glucocorticoids (corticosteroid nasal sprays and topical steroids are permissible). Use of oral steroids (\<20mg prednisone-equivalent/day) may be acceptable after review by the investigator.~11. Participants who care for severely immunosuppressed persons that require a protective environment should not receive LAIV, or should avoid contact with such persons for 7 days after receipt, given the theoretical risk for transmission of the live attenuated vaccine virus to close contacts. \[If yes, may be ineligible\]~12. 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).~13. 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.~14. History of blood dyscrasias, renal disease, or hemoglobinopathies requiring regular medical follow up or hospitalization during the preceding year~15. Use of any anti-coagulation medication such as Coumadin or Lovenox, or anti-platelet agents such as aspirin (except up to 325 mg. per day), Plavix, or Aggrenox will be reviewed by investigators to determine if study participation would affect the volunteer's safety or compliance with the protocol.~16. Has taken an influenza antiviral medication within 48 hours prior to study vaccination \[For volunteers receiving LAIV; If yes, may not eligible if unable to schedule at an appropriate interval\].~17. Receipt of blood or blood products within the past 6 months or planned use during the study.~18. Medical or psychiatric condition or occupational responsibilities that preclude participant compliance with the protocol~19. Receipt of an inactivated vaccine 14 days prior to study enrollment, or planned vaccinations prior to completion of last study visit (\~ 14 days after study vaccination)~20. Receipt of a live, attenuated vaccine within 60 days prior to enrollment of planned vaccination prior to completion of last study visit (\~ 14 days after study enrollment)~21. Need for allergy immunization (that cannot be postponed) until after the last study visit.~22. History of Guillain-Barré syndrome~23. Pregnant woman;~24. Breastfeeding woman \[if volunteer will receive LAIV4\]~25. Use of investigational agents within 30 days prior to enrollment or planned use during the study.~26. Donation of the equivalent of a unit of blood within 6 weeks prior to enrollment or donation of platelets within 2 weeks of enrollment or planned donation prior to completion of the last visit.~27. 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.

- Gender: ALL
- Minimum Age: 18 Years
- Maximum Age: 49 Years
- Healthy Volunteers: t

Study Arms:
- Pilot phase (Type: OTHER): Participants will receive the current seasonal quadrivalent, inactivated influenza vaccine (IIV4)/Fluzone® given intramuscularly to confirm the safety of administering the seasonal influenza vaccine 3-14 days prior to tonsillectomy.
- Study phase (Type: OTHER): Participants will be given the current year's quadrivalent, live, attenuated seasonal influenza vaccine (LAIV4)/FluMist® intranasally 3-14 days prior to tonsillectomy.

Based on this trial design, predict the completion outcome and termination type (if applicable).
