Whether or not you can have a baby if you get pregnant with the HPV 9-valent vaccine depends largely on how soon after the vaccine you become pregnant and your own situation to make a judgment. Currently, the safety of HPV9 vaccination for pregnant women and their fetuses is not clear. It is recommended that the HPV9 vaccine be administered 3-6 months after conception, during which time the vaccine will have no effect on the fetus or the pregnant woman. If a woman conceives within 3 months after HPV9 vaccination, she can do some relevant examinations after pregnancy, such as Down’s syndrome screening at 16 weeks of pregnancy and 4D ultrasound at 24 weeks. If there is no abnormality in the relevant examinations, it is proved that the fetus is normal, and in this case, the woman can continue the pregnancy. For women who are preparing for pregnancy, it is not recommended to receive HPV9 vaccination before pregnancy, but can wait until after breastfeeding.
