Summary

The purpose of this study is to see how much antibody (proteins produced by the immune system that help fight infections) the body makes after getting a flu vaccine. Researchers will also look at how the body reacts to the flu vaccine and how it affects the babies of pregnant women. The study will enroll approximately 240 women ages 18-39 years, including 180 pregnant women in their second or third trimester of pregnancy (at least 14 weeks pregnant) and 60 non-pregnant women. Participants will be randomly (by chance) assigned to 1 of 3 vaccine groups. Each participant will receive one shot of a 2010-2011 flu season licensed vaccine. The vaccine will be given as an intramuscular injection (shot in the muscle) in the upper arm. Study procedures include pregnancy testing, blood draws, and memory aids. Patient participation may be up to 8 months. The information from this study will help guide researchers in developing flu vaccines for pregnant women.

Eligibility Criteria

Inclusion Criteria

Pregnant women:

  • Pregnant female between the ages of 18 and 39 years, inclusive.
  • Is a singleton pregnancy and is from 14 weeks/0 days through 33 weeks/6 days of gestation.
  • Had at least one prenatal visit during which pregnancy was confirmed.
  • Is in good health, as determined by vital signs [heart rate /= 100.0 degrees F, within 72 hours of vaccination (This may result in a temporary delay of vaccination).
  • Has 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 (excluding non-melanoma skin cancer), a history of any hematologic malignancy, current bleeding disorder, or taking anticoagulants (a daily aspirin may be acceptable).
  • Long term use of glucocorticoids, including oral or parenteral, or 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 betamethasone or dexamethasone to accelerate fetal lung maturity.
  • Has a history of receiving immunoglobulin or other blood product (with exception of Rhogam) within the 3 months prior to enrollment in this study.
  • Has a diagnosis of a current and uncontrolled major psychiatric disorder.
  • Has been hospitalized for psychiatric illness, history of suicide attempt, or confinement for danger to self or others, within the past 10 years.
  • The subject is receiving any of the following 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. Subjects who are receiving an antidepressant drug (not listed above) and are stable for at least 3 months prior to enrollment without decompensating are allowed enrollment into the study.
  • Known active infection with human immunodeficiency virus (HIV), hepatitis B, or hepatitis C.
  • History of alcohol or drug abuse in the last 5 years.
  • Has a seizure disorder or is on an anti-seizure medication.
  • Has a history of Guillain-Barré Syndrome.
  • Has an acute or chronic medical condition that, in the opinion of the investigator would render vaccination unsafe, or would interfere with the evaluation of responses (this includes, but is not limited to, known cardiac disease, chronic hypertension, chronic liver disease, significant renal disease, unstable or progressive neurological disorder, transplant recipients or diabetes, juvenile diabetes [Type I] or advanced diabetes with renal disease or eye disease. Gestational diabetes controlled by diet or insulin is acceptable).
  • Has any of the following active medical conditions at the time of enrollment:

Hyperemesis gravidarium, premature labor (regular uterine contractions with cervical change), fetus with known major congenital anomaly or genetic abnormality, fetal growth restriction, preeclampsia, or known uterine anomaly (e.g. bicornuate uterus, submucosal fibroids > 5cm).

  • Has a history of preeclampsia or preterm birth 800 mcg/day of beclomethasone dipropionate or equivalent) within the preceding 6 months (nasal and topical steroids are allowed).
  • Has a history of receiving immunoglobulin or other blood product within the 3 months prior to enrollment in this study.
  • Has a diagnosis of a current and uncontrolled major psychiatric disorder.
  • Has been hospitalized for psychiatric illness, history of suicide attempt, or confinement for danger to self or others, within the past 10 years.
  • The subject is receiving any of the following psychiatric drugs: aripiprazole, clozapine, ziprasidone, haloperidol, molindone, loxapine, thioridazine, thiothixene, pimozide, fluphenazine, risperidone, mesoridazine, quetiapine, trifluoperazine, trifluop
