Influenza (flu) is a contagious respiratory virus that makes humans sick. Usually its symptoms are mild, but they can be dangerous. Researchers want to see if one way of giving the flu vaccine is more effective than another.
Objective:
To compare the body s ability to fight infection when a flu vaccine is given in the nose versus the arm.
Eligibility:
Healthy, nonsmoking adults ages 18 55. They must be willing to stay in isolation for at least 9 days. They must not have had the flu vaccine since September 1, 2018.
Design:
Participants must be willing to use birth control or abstinence from visit 1 until 8 weeks after getting the flu virus.
Participants will have at least 3 clinic visits over about a month. Visits may include:
Medical history
Physical exam
Blood and urine tests
Nasal samples collected
Heart and lung function tests
At the first visit, participants will get either:
Flu vaccine as injection in an arm muscle plus salt water sprays in the nose
OR flu vaccine as sprays in the nose plus salt water injection in an arm
Within the next few months, participants will stay in an isolation room for at least 9 days. They will be with up to 20 participants. Those who test positive for recreational drugs will leave the study. Participants will:
Repeat study tests
Answer questions about flu symptoms
Have the flu virus sprayed into their nose once
Be monitored by a medical team
Participants will have at least 2 follow-up visits and repeat study tests.

INCLUSION CRITERIA: 1. Greater than or equal to 18 and less than or equal to 55 years of age. 2. Non-smoker. 3. Have not received influenza vaccination of any type (whether licensed or unlicensed experimental vaccine) on or after September 1, 2018. Participants who enroll in our study must be informed of the Centers for Disease Control and Prevention (CDC) recommendation to receive seasonal influenza vaccination annually. Enrollees accept that half of study participants will receive licensed approved vaccination per the usual route, and half will receive it by an unapproved route with unknown efficacy and side effects. Enrollees should not plan to receive seasonal influenza vaccination from another source from enrollment through the final study visit (Phase 2, Day 56). 4. Willingness to remain in isolation for the duration of viral shedding (at a minimum 9 days) and to comply with all study requirements. 5. A male subject is eligible for the study if he meets one of the following criteria, beginning at least 4 weeks prior to enrollment and continuing until 8 weeks after administration of the human challenge virus: a. Is infertile, including history of successful vasectomy. b. Agrees to practice abstinence. c. Agrees that, with heterosexual intercourse with a fertile female partner, he will use a condom with spermicide and his female partner (including those who have undergone bilateral tubal ligation) will use an acceptable form of contraception (see inclusion criterion 6c). 6. A female participant is eligible for this study if she is not pregnant or breastfeeding and meets one of the following criteria, beginning at least 4 weeks prior to enrollment and continuing until 8 weeks after administration of the human challenge virus:: a. infertile, including postmenopausal status, (as defined by no menses for greater than or equal to 1 year) or history of hysterectomy. b. Agrees to practice abstinence. c. Agrees that, with heterosexual intercourse with a fertile male partner, she will use an acceptable form of contraception and her male partner will use a condom with spermicide. Acceptable effective methods of female contraception include the following: bilateral tubal ligation, implant of levonorgestrel, injectable progestogen, intrauterine device oral contraceptive pills and diaphragm with spermicide. 7. Willing to have samples stored for future research. 8. HIV uninfected with a negative test within 60 days of Phase 2, Day 0. 9. Agrees not to use IN medications (including but not limited to nasal sprays, sinus rinses), over-the-counter medications (including but not limited to aspirin, decongestants, antihistamines, and other non-steroidal anti-inflammatory drugs), and herbal medications (including but not limited to herbal tea or St. John s Wort), from 14 days prior to study enrollment through the final study visit (Phase 2, Day 56), unless approved by the investigator 10.

Known allergy to influenza vaccination or excipients contained in the influenza vaccine used. 8. Known allergy to lidocaine or phenylephrine. 9. Known allergy to treatments for influenza (including but not limited to oseltamivir or nonsteroidal anti-inflammatory medications). 10. Known allergy to 2 or more classes of antibiotics (e.g., penicillins, cephalosporins, fluoroquinolones, or glycopeptides). 11. Anatomic or functional defects of the nasopharynx that could affect nasal sampling such as chronic rhinitis, nasal septal defect, nasal polyps or recent or remote nasal surgery 12. Receipt of blood or blood products (including immunoglobulins) within 3 months prior to enrollment. 13. Donation of blood or blood products within 3 months prior to study enrollment. 14.
