The cervical vaccine is a vaccine to prevent cervical cancer, but it is not advisable to get the cervical vaccine if you are pregnant. The cervical cancer vaccine is currently used to prevent cervical cancer. There are three main types of vaccines: bivalent vaccine, quadrivalent vaccine and nine-valent vaccine, each of which can prevent different types of HPV infection, but the vaccination generally requires three vaccinations to be considered complete. In addition, the cervical vaccine generally requires three courses of vaccination, but if pregnancy is discovered during the vaccination process, it is not advisable to continue the vaccination and it is recommended to continue the uncompleted vaccination after delivery, and pregnant women who are already pregnant should not receive the cervical vaccine. The cervical vaccine is also not recommended for women with serious gynecological diseases, heart or cardiovascular diseases, or those who already have high-risk HPV infection in their cervix, although there is no relationship between the cervical vaccine and HPV infection, but if they are already infected with HPV, even the cervical vaccine is not very useful. In addition, the cervical vaccine currently on the market does not cover all HPV infections by type, so even if the cervical vaccine is administered, it will not exclude or prevent all cervical cancers 100% of the time. In conclusion, the current cervical vaccine has some limitations for the types of HPV infection that can be prevented. Generally, the cervical vaccine is not recommended for women who are pregnant or found to be pregnant during the vaccination process, or for women who already have serious gynecological diseases, heart or cardiovascular diseases, or who are already infected with HPV.
