Influenza Vaccine in Pregnant Women

Completed · Phase 2

Conditions studied: Influenza

In brief

In pregnant women, flu may cause complications like pneumonia (infection of the lungs) or hospitalization. In the United States (US) it is recommend that all women get flu vaccine if they are going to be pregnant or deliver during the flu season but only a few studies have measured a pregnant woman's immune response (the body's defense against the flu) after getting the flu vaccine. About 200, 18-39 year old, inclusive, pregnant women in their second or third trimester (from 14 weeks of gestation to term, inclusive) will be enrolled in this US based study. Participation will be about 8 months in duration. Women will be randomized (assigned by chance) to receive either Fluzone® or Fluarix®. Blood collection will occur on Day 0 and 28 days post vaccination.

A stable medical condition is defined as health outcomes of the specific disease are considered to be within acceptable limits in the last 3 months.
• Able to understand and comply with planned study procedures.
• Provides written informed consent prior to initiation of any study procedures.
• Agrees to sign medical release for herself and her infant(s) to allow study staff to gather pregnancy outcome data, if needed per clinical site policy.

You may not qualify if…

• Receipt of the 2008-2009 seasonal influenza vaccine [trivalent inactivated vaccine (TIV) or Flumist] prior to enrollment into the study.
• Has a known allergy to eggs, egg proteins, latex allergy or allergy to other components in the vaccines (i.e. formaldehyde, polyethylene glycol p-isooctylphenyl ether, sucrose, gelatin, polysorbate 80).
• Has a history of severe reactions following immunization with contemporary influenza virus vaccines.
• Has received any other licensed vaccines within 2 weeks (for inactivated vaccines) or 4 weeks (for live vaccines) prior to vaccination in this study or expects to receive a licensed product prior to Visit 4 (Day 28 visit) (except for inactivated influenza vaccine which may be received 2 weeks post vaccination with study product). Measles, mumps, rubella vaccine is permitted post-partum.
• Has a moderate-to-severe acute illness and/or an oral temperature greater than or equal to 100.0 degrees Fahrenheit, within 72 hours prior to vaccination. (This may result in a temporary delay of vaccination).
• Immunosuppression as a result of an underlying illness or treatment, or use of anti-cancer chemotherapy or radiation therapy within the preceding 36 months.
• Has an active neoplastic disease, a history of any hematologic malignancy, current bleeding disorder, or taking anticoagulants.
• Long term use of oral or parenteral steroids, high-dose inhaled steroids (>800 mcg/day of beclomethasone dipropionate or equivalent) within the preceding 6 months (nasal and topical steroids are allowed) or has received steroids for treatment of pre-term labor during this pregnancy.
• Has a history of receiving immunoglobulin or other blood product (with exception of Rhogam) within the 3 months prior to vaccination in this study.
• Has a diagnosis of a current and uncontrolled major psychiatric disorder.
• The subject is receiving listed psychiatric drugs (aripiprazole, clozapine, ziprasidone, haloperidol, molindone, loxapine, thioridazine, thiothixene, pimozide, fluphenazine, risperidone, mesoridazine, quetiapine, trifluoperazine, trifluopromazine, chlorprothixene, chlorpromazine, perphenazine, olanzapine, carbamazepine, divalproex sodium, lithium carbonate or lithium citrate).

• History of alcohol or drug abuse in the 1 year prior to enrollment.
• Has a history of Guillain-Barré syndrome.
• Has a seizure disorder or is on an anti-seizure medication for a seizure disorder.

• Has an acute or chronic medical condition that, in the opinion of the investigator would interfere with the evaluation of responses (this includes, but is not limited to: known chronic liver disease, significant renal disease, transplant recipients, uncontrolled diabetes, juvenile diabetes (Type 1) or advanced diabetes with renal and eye disease; diabetes controlled by diet or oral agents is acceptable).
• Has any condition that would, in the opinion of the site investigator, place the subject at an unacceptable risk of injury or render the subject unable to meet the requirements of the protocol.
