The vaccine for cervical cancer should not be given when you are pregnant. The reason is that if the cervical cancer vaccine is administered during pregnancy, the drug may have some effect on the fetus. Therefore, if you become pregnant during the cervical cancer vaccination, you can stop the medication at this time and get the cervical cancer vaccination again after the birth in the interval cycle. If you have not yet had the cervical cancer vaccine and you are pregnant at this time, you can wait until after delivery to have the cervical cancer vaccine. This is because after the cervical cancer vaccination, there are also certain side effects that can cause dizziness, headache or skin conditions so that such adverse reactions will not have certain effects on the fetus. If you are allergic to proteins during the cervical cancer vaccination, it is also not recommended at this time to avoid side effects.
