The vaccine to prevent cervical cancer is also known as the HPV vaccine. It is generally recommended that women who have had sex have a TCT and HPV test before taking the HPV vaccine in order to exclude pre-cancerous or even cancerous lesions of the cervix, while women who are not sexually active generally do not need to be tested. At present, there are more than 200 subtypes of HPV isolated, and there are more than 60 types that can infect people. But not all of the hpv virus will lead to cervical cancer, such as skin warts, foot warts, etc. is also due to hpv infection. Women who have a history of sexual intercourse are advised to undergo cervical high-risk HPV genetic testing and cervical exfoliative cell cytology (TCT) before taking the cervical cancer vaccine. If the results are abnormal, consult a doctor as soon as possible, and have a professional doctor assess whether cervical lesions or even cervical cancer have occurred, and evaluate whether it is possible to take the cervical cancer vaccine. At present, there are mainly bivalent, quadrivalent and nine-valent HPV vaccines in the clinic. It is recommended that women between the ages of 16 and 26 get the HPV 9-valent vaccine as early as possible because the 9-valent can prevent more subtypes of the HPV virus, and women who have had the HPV vaccine should also be screened for cervical cancer on a regular basis.
