B: Inclusion Criteria:

* Male or female, 18 to 49 years of age (not yet reached their 50th birthday) at the time of randomization
* Healthy by medical history and physical examination
* Written informed consent and any locally required authorization (eg, Health Insurance Portability and Accountability Act \[HIPAA\] in the United States of America \[USA\], European Union \[EU\] Data Privacy Directive in the EU) obtained from the subject/legal representative prior to performing any protocol-related procedures, including screening evaluations
* Females of childbearing potential, (ie, unless surgically sterile \[eg, bilateral tubal ligation, bilateral oophorectomy, or hysterectomy\], has sterile male partner, is at least 1 year post menopause, or practices abstinence) must use an effective method of avoiding pregnancy (including oral, transdermal, or implanted contraceptives, intrauterine device, female condom with spermicide, diaphragm with spermicide, cervical cap, or use of a condom with spermicide by the sexual partner) for 30 days prior to the first dose of investigational product, and must agree to continue using such precautions for 60 days after the second dose of investigational product. In addition, the subject must also have a negative urine or blood pregnancy test at screening and, if screening and Day 1 do not occur on the same day, on the day of vaccination prior to randomization.
* Males, unless not sexually active, must use an effective method of birth control with a female partner and must agree to continue using such contraceptive precautions for at least 30 days after the second dose of investigational product (from Day 1 through Day 59 of the study)
* Subject is available by telephone
* Subject is able to understand and comply with the requirements of the protocol, as judged by the investigator
* Subject is able to complete follow-up period of 180 days after Dose 2 as required by the protocol

Exclusion Criteria:

* History of hypersensitivity to any component of the investigational product including egg or egg protein, gelatin or arginine, or serious, life-threatening, or severe reactions to previous influenza vaccinations
* History of hypersensitivity to gentamicin
* Any condition for which the inactivated influenza vaccine is indicated, including chronic disorders of the pulmonary or cardiovascular systems (eg, asthma), chronic metabolic diseases (eg, diabetes mellitus), renal dysfunction, or hemoglobinopathies that required regular medical follow-up or hospitalization during the preceding year
* Acute febrile (\> 100.0°F oral or equivalent) and/or clinically significant respiratory illness (eg, cough or sore throat) within 14 days prior to randomization
* History of asthma
* Any known immunosuppressive condition or immune deficiency disease, including human immunodeficiency virus infection, or ongoing immunosuppressive therapy
* History of Guillain-Barré syndrome
* A household contact who is severely immunocompromised (eg, hematopoietic stem cell transplant recipient, during those periods in which the immunocompromised individual requires care in a protective environment); subject should additionally avoid close contact with severely immunocompromised individuals for at least 21 days after receipt of investigational product
* Receipt of any investigational agent within 30 days prior to randomization, or expected receipt through 30 days after the second dose of investigational product (use of licensed agents for indications not listed in the package insert is permitted)
* Expected receipt of antipyretic or analgesic medication on a daily or every other day basis from randomization through 14 days after receipt of each dose of investigational product
* Administration of intranasal medications within 14 days prior to randomization, or expected receipt through 14 days after administration of each dose of investigational product
* Receipt of any nonstudy vaccine within 30 days before or after Dose 1 or expected receipt of any nonstudy vaccine within 30 days before or after Dose 2
* Known or suspected mitochondrial encephalomyopathy
* Subject is pregnant or a nursing mother
* Any condition (eg, chronic cough, allergic rhinitis) that, in the opinion of the investigator, would interfere with evaluation of the investigational product or interpretation of subject safety or study results
* Subject or immediate family member of subject is an employee of the clinical study site or is otherwise in involved with the conduct of the study
C: Inclusion Criteria:

* Age 18-49 years
* Available for clinic visits at Tufts-New England Medical Center
* Written informed consent and Health Insurance Portability and Accountability Act (HIPAA) obtained
* Ability of participant to understand and comply with the requirements of the protocol

Exclusion Criteria:

* History of any medical conditions for which the CDC states should not be vaccinated with LAIV (asthma, reactive airways disease, other chronic disorders of the pulmonary or cardiovascular systems; metabolic diseases such as diabetes, renal dysfunction, and hemoglobinopathies; or persons with known or suspected immunodeficiency diseases)
* Self-reported vaccination with the influenza vaccine for the current influenza season (2007-8); vaccination with any vaccine within the one month period prior to study enrollment or intent to receive any other vaccine during the study period; hypersensitivity to any influenza vaccine components including thimersol or egg or Guillain-Barre syndrome
* Self-reported treatment with immunomodulator/immunosuppressor drugs (interleukins, corticosteriods (oral or inhaled)), G(M)-CSF in 4 weeks before enrollment or self-reported history of IL-2 administration within 5 years; use of theophylline preparations or warfarin because of the theoretical possibilities of enhanced drug effects and toxicities following influenza vaccination; medication use that might affect the immune response to a vaccine or effects of LGG (no antibiotics during the previous 4 weeks)
* Current alcohol, substance abuse, or systemic/psychiatric illness that potentially could interfere with compliance and ability to make study visits
* Health care or day care workers or close contacts with immunosuppressed persons because of the theoretical risk that LAIV could be transmitted to the immunosuppressed person and cause disease, per CDC recommendations
* Use of LGG or other probiotics in 4 weeks before enrollment. Yogurt consumption is not an exclusion criteria, but subjects will be asked to avoid consumption of other lactobacilli and probiotic organisms during the study period
* Abnormalities upon physical examination
* Acute febrile illness on day of intended immunization - immunization deferred until illness resolved
* Routine laboratory tests outside the limits outlined for this study:

  4. Platelets 125,000-550,000 /mm\^3
  5. ALT \<= upper limit of normal
  6. Serum creatinine \<= upper limit of normal
  7. Normal urinalysis (negative glucose, negative or trace protein, and negative or trace hemoglobin)
  8. Negative beta-HCG pregnancy test (urine or serum) for women presumed to be of reproductive potential because LAIV is contraindicated in pregnant women
