Vaginal birth after Cesarean (VBAC) rate

Vaginal birth refers to a mother delivering her baby through her vagina. A Cesarean delivery refers to the surgical removal of a baby through an incision in the mother’s abdomen. Vaginal birth after Cesarean (VBAC) is used to describe a vaginal delivery of a child when the mother has delivered a baby through Cesarean delivery in a previous pregnancy.

There are no nationally-agreed standards on when VBAC is appropriate. However, many women prefer to avoid a surgical delivery when possible, and some women discuss the possibility of VBAC with their obstetricians.
