If a woman finds out that she is pregnant after the cervical quadrivalent vaccine, she has to choose a treatment plan depending on the case. If there is no pregnancy planned, you can choose to have a medical abortion or an abortion depending on the number of days of pregnancy. If you have a pregnancy plan, you can continue the pregnancy without abortion. The cervical cancer quadrivalent vaccine itself is a protein and not a virus, so it does not usually affect the fetus. The cervical cancer quadrivalent vaccine requires three injections. If the patient does not finish all the injections, she should stop the injections after pregnancy because no human trials have been conducted, so it is not 100% certain that there is no effect at all, so stop the injections after pregnancy. After the birth of a child, the cervical quadrivalent vaccine can be administered even while breastfeeding, and there is no effect on the re-injection in this case.
