Treatment Details

Study Objectives

Outcome measures can provide a clearer picture of what you can expect from a treatment.
Primary outcome measures
Pre-Eclampsia
Incidence of preeclampsia in each arm of the study with regards to timing of Tdap vaccination
Secondary outcome measures
Assessment of other potential risk factors for preeclampsia inclusive of BMI, hypertension, prior history of preeclampsia, first pregnancy
Other outcome measures
Compare the placental and maternal biomarkers of preeclampsia in order to devise a better formula for positive prediction of preeclampsia

Trial Design

2Treatment groups
Active Control
Group I: Tdap vaccinations at gestational week 36Active Control1 Intervention
Pregnant women entering into this clinical research study and signing informed consent at week 12 will be randomized to either receive Tdap vaccination at week 28 or week 36. Subjects receiving Tdap vaccination at week 36 will receive a placebo injection at week 28. Subjects will be followed with routine standard of care throughout their pregnancy and have routine clinic visits from which study visits will include weeks 12, 20, 28, 36, and 2 weeks postpartum. Data will be collected at each of these visits with special attention to the development of preeclampsia and fetal health
Group II: Tdap vaccinations at gestational week 28Active Control1 Intervention
Pregnant women entering into this clinical research study and signing informed consent at week 12 will be randomized to either receive Tdap vaccination at week 28 or week 36. Subjects receiving Tdap vaccination at week 28 will receive a placebo injection at week 36. Subject will be followed with routine standard of care throughout their pregnancy and have routine clinic visits from which study visits will include weeks 12, 20, 28, 36, and 2 weeks postpartum. Data will be collected at each of these visits with special attention to the development of preeclampsia and fetal health
