The cervical cancer vaccine is not recommended during preparation for pregnancy. The cervical cancer vaccine is an effective way to prevent HPV infection. The World Health Organization has published a position paper on HPV vaccine that recommends that HPV vaccine is not recommended for people who have a recent pregnancy plan, and that conception should be avoided as much as possible within 2 months of completing the last HPV vaccination. If an unintended pregnancy is detected after vaccination, the uncompleted vaccination should be discontinued. If the vaccination has been completed, there is no need to intervene in the pregnancy. There are limited data on HPV vaccination in women during pregnancy and it is not possible to implement clinical studies to evaluate it. Women planning a pregnancy are advised to delay vaccination until the end of pregnancy and breastfeeding. Some data suggest that pregnancy within 30 days of HPV vaccination around 30 days of conception may raise the risk of spontaneous abortion. If you plan to become pregnant after cervical vaccination, you need to consult with a professional obstetrician and gynecologist to decide in detail, and take care to avoid smoking, alcohol abuse and other bad habits during the preparation for pregnancy.
