Hi, I am 37 weeks and just had the whooping cough booster (along with my partner and parents, who will be spending time with baby once it arrives). After seeing a clip on the news about it, I did research online (MoH, etc) and asked the doctor and my midwife, who all recommended getting the booster as there are two known outbreaks in NZ at the moment, in Akld and ChCh. I have had no adverse reaction other than a sore arm. I felt it was more important to create an environment of protection before birth, rather than wait - obviously a personal decision. Hope your tests came back OK.
