I am pretty sure that the vaccine for whopping cough is not live therfore if you get the booster the virus cant be passed on to bubs. If you are birthing in a hospital Id ask the the dr's there for it, or see your gp when you are discharged. I had the vaccination after dd1 at her first lot of vaccinations, I think it has pertussis (whoping cough), diptheria and tetanus so you get the protection from all 3. The governemnt vaccine info line is 1800 671 811give them a call.
