For those who become pregnant during inactivated viral vaccination, such as HPV (human papillomavirus) vaccine, new crown vaccine, etc., although the effect on the embryo is not clear, but when the ultrasound examination of the embryo is well developed can continue to be pregnant and until the delivery of the baby; however, there are some ultrasound suggests that the embryo is not well developed, and you need to comply with the doctor’s advice to terminate the pregnancy in a timely manner. Contraindications to vaccination include pregnancy, breastfeeding and acute stage of disease, so women in preparation for pregnancy should also pay attention to avoid vaccination, but unplanned pregnancies found during the vaccination period do not necessarily have to be absolutely aborted, and follow the doctor’s instructions for strict obstetric examination, as well as mid-pregnancy screening and ultrasound system of fetal structure to rule out developmental problems. If you have any other questions, it is recommended that you consult a medical professional for guidance.
