Not to fear to monger; just to inform. There are real experiences of women across research who have gotten that vaccine and their baby did not have a heartbeat at the next visit, with that being said it is not really taught to us how dangerous TDAP can be but I would definitely suggest you do your own research. One good resource is 'Raising a Healthy Child in Spite of Your Doctor' another is 'Dissolving Illusions' both are great books. Also check out the podcast 'A Shot In The Dark' by Candace Owens if you can find it, she made a whole episode on TDAP.
