Cervical cancer vaccination generally does not require examination because the development of cervical cancer is closely related to HPV high-risk infection. The cervical cancer vaccine can only prevent cervical cancer caused by several subtypes of HPV, but there are many kinds of HPV high-risk viruses. Currently, HPV vaccination is divided into bivalent, quadrivalent and nine-valent vaccines, which can prevent cervical cancer caused by two, four and nine subtypes of HPV infection respectively. Therefore, as long as you are not a cervical cancer patient, you can receive the cervical cancer vaccine regardless of whether you appear to be HPV positive or not. The titers of antibodies produced after cervical cancer vaccination vary, so it is advisable to test the antibody titers after vaccination to determine whether protection is produced.
