NCT01173211

Brief 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.

Outcome Measures

Primary Outcomes (11)

  • Number of Participants Reporting Vaccine-associated Unsolicited Non-serious Adverse Events

    Unsolicited non-serious adverse events were collected from participants at follow up contacts, either by phone or in clinic, through 28 days after vaccination. Association to vaccination was determined by a clinician licensed to make a medical diagnosis and listed on the site's Federal Drug Administration's Form 1572.

    Day 0 through Day 28 post vaccination

  • Number of Participants Reporting Maternal Complications of Pregnancy, Labor and Delivery

    Participants were contacted after delivery, and medical records reviewed, to collect complications experienced during pregnancy, labor and delivery. The data collection process followed a prospectively-defined list of complications reported for this outcome measure, some of which may have also been reported as serious adverse events if otherwise meeting those requirements.

    During the pregnancy and at the time of delivery

  • Number of Participants Reporting Neonatal Complications

    Participants were contacted after delivery, and medical records reviewed, to collect neonatal complications. The data collection process followed a prospectively-defined list of complications reported for this outcome measure, some of which may have also been reported as serious adverse events if otherwise meeting those requirements.

    At time of delivery

  • Number of Participants Reporting Vaccine-associated Serious Adverse Events (SAEs)

    Serious adverse events included any untoward medical occurrence that resulted in death of the mother, fetus or infant; was life threatening to mother, fetus or infant; was a persistent/significant disability/incapacity; required in-patient hospitalization or prolongation thereof; was a congenital anomaly/birth defect in fetus or infant; or may have jeopardized the mother, fetus or infant, or required intervention to prevent one of the outcomes, or was described as Guillain-Barré Syndrome. Association was determined by a clinician licensed to diagnose and listed on the site's FDA Form 1572.

    Day 0 through Day 180 after vaccination

  • Number of Participants Reporting Solicited Subjective Local Reactions After Vaccination

    Participants maintained a memory aid to record daily the occurrence of local reactions of pain, tenderness and swelling for 8 days after vaccination (Day 0-7) based on their interference with daily activities. Participants are counted if they reported experiencing the symptom at any severity on any of the 8 days.

    8 days after vaccination (Days 0-7).

  • Number of Participants Reporting Solicited Quantitative Local Reactions After Vaccination

    Participants maintained a memory aid to record daily the occurrence of local reactions of redness and swelling for 8 days after vaccination (Day 0-7). If the reaction was present, the maximum diameter was measured in millimeters (mm). Participants are counted if they reported experiencing the reaction with any measurement greater than 0 mm on any of the 8 days.

    8 days after vaccination (Days 0-7).

  • Number of Participants Reporting Solicited Subjective Systemic Reactions After Vaccination

    Participants maintained a memory aid to record daily the occurrence of systemic symptoms of feverishness, malaise, myalgia, headache, and nausea for 8 days after vaccination (Day 0-7) based on their interference with daily activities. Participants are counted if they reported experiencing the symptom at any severity on any of the 8 days.

    8 days after vaccination (Days 0-7).

  • Number of Participants Reporting Fever After Vaccination

    Participants were provided with a thermometer and a memory aid on which to record daily oral temperatures for 8 days after vaccination (Day 0-7). The protocol defined fever as oral temperature of 37.8 degrees Celsius or higher. Participants are counted as experiencing fever if they reported oral temperatures of 37.8 degrees Celsius or higher on any of the 8 days.

    8 days after vaccination (Days 0-7).

  • Hemagglutination Inhibition Assay (HAI) Geometric Mean Titer (GMT) Against Each Antigen in the 2010-2011 Seasonal Influenza Trivalent Influenza Vaccine

    Blood was collected for HAI assay at Day 0 prior to vaccination and again at 28 days following vaccination. The HAI assay was conducted with the three antigens in the 2010-2011 seasonal inactivated TIV: Influenza B antigen, H1N1 antigen, and H3N2 antigen.

    Day 0 prior to and Day 28 following vaccination

  • Number of Participants With 4-fold or Greater Serum HAI Antibody Titer Increases Against Each Antigen in the 2010-2011 Seasonal Influenza Trivalent Influenza Vaccine

    Blood was collected from all participants prior to vaccination as well as 28 days after vaccination. The HAI assay was conducted with the three antigens in the 2010-2011 seasonal inactivated TIV: Influenza B antigen, H1N1 antigen, and H3N2 antigen. A participant met the threshold of a 4-fold rise in titer if the Day 0 titer was less than 10 (the assay's lowest level of detection) and the Day 28 post vaccination titer was 40 or greater, or the Day 0 titer was greater than or equal to 10 and the Day 28 post vaccination titer was an increase by 4-fold or more.

    Day 0 prior to and Day 28 after vaccination

  • Number of Participants With HAI Antibody Titer of 40 or Greater Against Each Antigen in the 2010-2011 Seasonal Influenza Trivalent Influenza Vaccine

    Blood was collected from all participants prior to vaccination as well as 28 days after vaccination. The HAI assay was conducted with the three antigens in the 2010-2011 seasonal inactivated TIV: Influenza B antigen, H1N1 antigen, and H3N2 antigen. Participants are counted if the titer at the timepoint is 40 or greater.

    Day 0 prior to and Day 28 after vaccination
