If you become pregnant after receiving the cervical cancer vaccine, the fetus can be retained, but you should go to the hospital for regular checkups. The cervical cancer vaccine is able to hinder most types of human papillomavirus, genital warts and cervical cancer. It is an inactivated vaccine and it is best to get pregnant 3-6 months after the vaccine. However, if you find out that you are pregnant after the vaccine, the fetus can be retained and the cervical cancer vaccine usually does not cause much harm to the fetus. If only one or two shots have been given, the rest of the vaccine cannot be revaccinated and should be waited until after delivery. During pregnancy, you need to go to the hospital for regular maternity checkups. To summarize, if you are pregnant after taking the cervical cancer vaccine, you should pay more attention to the maternity checkups, and if there is any abnormality, you need to inform your doctor in time.
