If you become pregnant during the cervical cancer vaccination, you should first suspend the cervical cancer vaccination, continue the pregnancy and have regular obstetric checkups. Under normal circumstances, the cervical cancer vaccine usually requires three injections. It is recommended to use contraception during the cervical vaccination and plan for pregnancy three months after the full vaccination. Clinical studies have not found that the cervical cancer vaccine will affect the development of embryo, and most women who get pregnant after or during the vaccination usually have no obvious discomfort, and there is no obvious effect on the growth and development of the fetus. Therefore, there is no need for special treatment for pregnancy during the vaccination period, only regular pregnancy check-ups are needed, and if any abnormality is found in the pregnant woman and the fetus, timely and targeted treatment can be carried out.
