It is recommended that pregnancy should take place 3-6 months after receiving the HPV vaccine. The HPV vaccine is mainly used to prevent the occurrence of cervical cancer in women. There are individual differences in the time to produce antibodies after vaccination, and the safety of the vaccine for pregnant women and fetuses is not yet clear. Therefore, it is generally recommended to wait 3-6 months after vaccination before becoming pregnant. If you become pregnant unexpectedly during or after vaccination, you do not need to terminate the pregnancy, but can continue to undergo prenatal checkups as scheduled. If you have not received the HVP vaccine as scheduled, you can suspend the vaccination and wait for the breastfeeding period to pass before receiving the remaining doses. There are many subtypes of HVP virus, even the nine-valent only targets nine subtypes, so even after receiving the nine-valent vaccine, it is necessary to have regular cervical checkups.
