HPV vaccination is not recommended during the preparation period, and it is recommended to wait 3-6 months after HPV vaccination before getting pregnant. According to the recommendation of the Chinese Expert Consensus on the Clinical Application of Human Papillomavirus Vaccine, HPV vaccination is not recommended for pregnant and breastfeeding women, and those who are preparing for pregnancy in the near future are also recommended to wait until they are breastfeeding before receiving the vaccine. If you become pregnant during HPV vaccination, you do not need to terminate the pregnancy just because of the vaccination, but you need to evaluate the condition of the fetus regularly and continue HPV vaccination after delivery and breastfeeding. The HPV vaccine is an inactivated vaccine that stimulates the body’s immune system to produce antibodies and is not pathogenic, but it is generally recommended to wait 3-6 months after vaccination before becoming pregnant. Therefore, HPV vaccination is not recommended during the preparatory period.
