It is recommended to prepare for pregnancy after 3-6 months after the cervical vaccination. According to China’s expert consensus on human papillomavirus vaccine, HPV vaccination is not recommended for preventive vaccination of women during pregnancy. If you are planning to get pregnant recently, it is recommended that you postpone the vaccination until after breastfeeding, and if you become pregnant unintentionally after the vaccination, you should stop the uncompleted dosage of the vaccination, and for those who have completed the vaccination, there is no need to intervene. There is no data showing that cervical HPV vaccination causes adverse effects on the embryo. If pregnancy is planned, pregnancy can be prepared 3-6 months after cervical HPV vaccination. It is important to use adequate contraception to prevent unintended pregnancy during the cervical HPV vaccination cycle.
