I had my Tdap vaccine last week and I had a sore arm. No other reactions to the vaccine. My daughter will benefit from the immunoglobulin G (igG) that my body makes and passes onto her via the placenta. Since I can make the igG antibody for her, she will be much less likely to get infected with tetanus, diphtheria, or pertussis aka whooping cough. Getting the vaccine after she's born might help a little, it's nothing compared to what you can do for her immune system while you're pregnant. As far as the possibility of stillbirth, the way vaccine safety is reported is pretty confusing. If anything bad happens after you get the shot, it gets reported. Sometimes these things are actually caused by the vaccine and many times they just happen at the same time. So when everything gets reported, even though some of it had absolutely nothing to do with the vaccine, other people who need to blame something for a tragedy will blame the vaccine. It's just the natural human cognitive bias. Please talk to your healthcare provider and nurses if you have questions. Write them down and take them to your appointment if you have to. I hope you get the Tdap vaccine and that you have a happy, healthy baby. If you get it, relax your arm, move it as much as possible after you've gotten it, and then treat the pain with your favorite scoop of ice cream.
