Yes. If you develop tetanus during pregnancy your own life would be in danger as would be the pregnancy. Two doses of vaccine 4 wks apart( at least 2wks before delivery) would not only protect you but provide the baby with some protection for several wks after birth. It is ok to get the vaccine while pregnant.
