I am a physician that works doing anesthesia on labor and delivery and I asked my Ob-gyn colleagues about this today. There is absolutely no contraindication to getting TDaP when you are pregnant because the pertussis portion is killed vaccine. The only vaccines you shouldn't get while pregnant are those that contain live virus (like MMR and Flumist). I would really encourage you to get your children the pertussis vaccine also because there have been a lot of pertussis outbreaks recently because the herd immunity is waning. Everyone in our department had to be vaccinated last year because a co-worker had it. If you have ever seen anyone with pertussis you would definitely want your children protected - you can cough so hard you break ribs! The TDaP is routinely given to all post partum women here as soon as they deliver as a public health initiative to stop the spread of pertussis.
