You can get pregnant six months after three injections of cervical quadrivalent HPV vaccine. The injection method of cervical quadrivalent HPV vaccine is that after the first injection, the second injection is given at an interval of two months, after the second injection, the third injection is given at an interval of four months, and when the third injection is given six months later, you can get pregnant. Although there are no clinical reports on the effects of pregnancy during the HPV vaccination on the baby, it is best to stop the injection for six months before getting pregnant to be on the safe side. If you become pregnant during the vaccination period, you need to stop the vaccination, do your pregnancy checkups, and wait until the baby is born to get the rest of the HPV vaccine. You can prepare for pregnancy after three doses of the HPV vaccine under your doctor’s supervision, and then do your pregnancy checkups under your doctor’s supervision after you get pregnant.
