New Study Finds Tdap Vaccine During Pregnancy Not Associated With Increased Risk of Preterm Delivery or Small Birth Size
A study looking at safety of the Tdap vaccine during pregnancy was published in the Journal of the American Medical Association today.
Researchers used administrative and electronic health record data from two California Vaccine Safety Datalink sites to study whether maternal Tdap vaccination during pregnancy is associated with increased risks of health problems for the mother or baby.
The study found that Tdap vaccination during pregnancy was not associated with increased risk for hypertensive disorders of pregnancy, preterm birth, or having a baby who is small for his or her gestational age.
This study adds important information on the safety of Tdap vaccination during pregnancy, following continued widespread pertussis transmission and current recommendations to routinely vaccinate during pregnancy.
