No corresponding medical examination is needed before cervical cancer vaccination without sexual history, but one must know whether one has protein allergy or enzyme allergy in the past, and if one has these two allergies, cervical cancer vaccination is not recommended. Women with a history of sexual intercourse need to undergo a corresponding medical examination before receiving the cervical cancer vaccine, mainly to find out whether the cervical epithelium is diseased and requires cervical cancer screening. When the results of the cervical cancer screening are not problematic and the health condition of the body allows, the cervical cancer vaccine can be administered. The cervical cancer vaccine requires a total of three doses, and only after all three doses have been administered will it be able to prevent cervical cancer.
