Title: Vaccination of HIV-uninfected Pregnant Women With Trivalent Influenza Vaccine in the Prevention of Influenza Illness During Early Infancy and in Mothers: Randomized Controlled Phase III Trial Evaluating Safety, Immunogenicity and Efficacy
Brief Summary: Randomised, double blind, placebo controlled trial to assess safety, immunogenicity and efficacy of Trivalent Influenza vaccine in HIV uninfected pregnant women


Options:
A: Inclusion Criteria:

* Male or female aged 18 and older, inclusive, at the time of providing informed consent.
* Females of child bearing potential (i.e., ovulating, pre-menopausal, not surgically sterile) must be abstinent or be willing to use a medically accepted contraceptive regimen for the duration of the study. Females of child bearing potential must return a negative urine pregnancy test result at enrolment and prior to each study vaccination.

Exclusion Criteria:

* Known hypersensitivity to a previous dose of influenza virus vaccine or allergy to eggs, chicken protein, thimerosal, neomycin, polymyxin, or any components of the Study Vaccine.
B: 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:

  1. hemoglobin \>=11.5g/dL for women; \>=13.5 g/dL for men
  2. WBC 3,300-12,000 cells/mm\^3
  3. Differential within normal range
  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
  9. negative HIV test
  10. negative hepatitis B surface antigen
  11. negative anti-HCV
C: Inclusion Criteria:

* Pregnant women age 18 years to less than 39 years.
* Gestational age greater than or equal to 20 weeks to less than 34 weeks documented by the approximate date of the last menstrual period and corroborated by physical exam.
* Documented to be HIV-1 uninfected on two assays used in the PMTCT program undertaken within 12 weeks of study enrolment.
* Able to understand and comply with planned study procedures.
* Provides written informed consent prior to initiation of study.

Exclusion Criteria:

* Receipt of TIV, other than through the study, during the current influenza season documented by medical history or record.
* Receipt of any live licensed vaccine less than or equal to 28 days or inactivated licensed vaccine (except for tetanus toxoid vaccine) less than to equal to 14 days prior to study-vaccine.
* Participants in the nested immunogenicity cohort cannot receive ANY vaccine (including tetanus toxoid) within 14 days of the study-vaccine.
* Receipt of a non-licensed agent (vaccine, drug, biologic, device, blood product, or medication) less than or equal to 28 days prior to vaccination in this study, or expects to receive another non-licensed agent before delivery unless study approval is obtained.
* Any significant (in the opinion of the site investigator) acute illness and/or oral temperature greater than or equal to 38 degrees C ≤ 24 hours prior to study entry.
* Use of anti-cancer systemic chemotherapy or radiation therapy ≤ 48 weeks of study enrollment, or has immunosuppression as a result of an underlying illness or treatment.
* Long term use of glucocorticoids, including oral or parenteral prednisone ≥ 20 mg/day or equivalent for more than 2 consecutive weeks (or 2 weeks total) ≤ 12 weeks of study entry, or high-dose inhaled steroids (\>800 mcg/day of beclomethasone dipropionate or equivalent) ≤ 12 weeks before study entry (nasal and topical steroids are allowed).
* Receipt of corticosteroids for preterm labor ≤ 14 days before study entry.
* Receipt of immunoglobulin or other blood products (with exception of Rho D immune globulin) ≤ 12 weeks prior to enrollment in this study or is scheduled to receive immunoglobulin or other blood products (with the exception of Rho D immune globulin) during pregnancy or for the first 24 weeks after delivery.
* Receipt of IL2, IFN, GMCSF or other immune mediators ≤ 12 weeks before enrollment.
* Uncontrolled major psychiatric disorder.
* History of a severe adverse reaction to previous TIV.
