HPV is human papillomavirus, and the bivalent HPV vaccine protects against HPV types 16 and 18.
HPV has been linked to the development of a variety of diseases, with high-risk HPV types 16 and 18 being most closely associated with the development of cervical cancer. In addition, HPV types 16 and 18 can lead to vulvar cancer, vaginal cancer, oropharyngeal cancer, perihepatic cancer, genital warts and other diseases.
The bivalent HPV vaccine is a prophylactic vaccine against HPV types 16 and 18 that prevents initial HPV 16 and 18 infections and the associated lesions they cause. However, for women with pre-existing HPV subtypes 16 and 18 infections, the bivalent HPV vaccine neither treats the infection nor accelerates the removal of the virus from the body.
Therefore, before injecting HPV vaccine, you need to complete the cervical cancer screening test, and those who meet the requirements for vaccination will be vaccinated according to the doctor’s instructions. However, the vaccination does not mean that you will not get cervical cancer, and you still need to have regular medical checkups.
