there are many mummies who took the first few jabs during pregnancy, even before booster. the impact is baby receiving beneficial antibodies from you that protect them from covid. the impact covid on your baby in the future is worse than the booster
Gonna take after my first trimester, that is what Dr advised. I'm carrying twins, now week 12. My first 2 jabs were moderna but my side effects were bad, so for booster I am considering Pfizer instead.
