If you find out you are pregnant after the cervical cancer vaccination and the fetus can be retained, you should stop continuing the rest of the cervical cancer vaccination and continue the rest of the vaccination after the postpartum breastfeeding period is over. The cervical cancer vaccine is an inactivated vaccine, which is mainly used to prevent HPV infection and thus to prevent the occurrence of cervical cancer. It is best to wait six months or one year after the cervical cancer vaccination before getting pregnant. If you find out you are pregnant after all three vaccinations, there will be no effect on the fetus. It is recommended that you follow the doctor’s advice and have regular pregnancy tests after pregnancy, and don’t worry too much, as being nervous is not good for the fetus. You should keep your mood comfortable, adopt a healthy lifestyle, develop regular habits, do not stay up late, and have timely Down screening test and 4D ultrasound examination during 20-26 weeks of pregnancy to terminate the pregnancy in time if abnormalities are found.
