Whether domestic bivalent cervical cancer vaccine is necessary or not depends on the specific situation. First of all, there is no significant difference between domestic and imported bivalent cervical cancer vaccine in terms of preventive effect, and domestic vaccine may be cheaper, so it is not recommended to use whether domestic vaccine is necessary or not as a criterion. The bivalent cervical cancer vaccine is suitable for women between the ages of 9 and 45, and the protection range is generally not as wide as the quadrivalent and nine-valent cervical cancer vaccines, so it is more suitable for people without sexual history. The bivalent cervical cancer vaccine is also necessary for women with high risk factors for cervical cancer, such as those with a history of cervical cancer disease in their immediate family, as well as those who smoke, have early sex, have more births, have more abortions, and have multiple sexual partners. However, since the protection of the bivalent cervical cancer vaccine is not as extensive as that of the quadrivalent and nine-valent cervical cancer vaccines, this group of people can also get the quadrivalent or nine-valent vaccine if their conditions support it. The cervical cancer vaccine is mainly used to prevent human papilloma virus (HPV) infection, which is one of the risk factors for the development of cervical cancer, especially persistent high-risk HPV infection can lead to cervical precancerous lesions, which in turn induce cervical cancer. The domestic bivalent cervical cancer vaccine, which can prevent two types of cervical cancer viruses, high-risk HPV16 and HPV18, can prevent more than 80% of cervical cancer diseases. Therefore, it is recommended that women who are eligible for cervical cancer vaccination should be actively vaccinated, and the protection effect of the vaccine will be better if women are vaccinated with domestic bivalent cervical cancer vaccine before they have no sexual intercourse. However, it is worth noting that it is not 100% safe from cervical cancer after cervical cancer vaccination. Usually, the probability of being infected with high-risk HPV16 and HPV18 cervical cancer viruses is lower after getting the domestic bivalent cervical cancer vaccine. However, there are many types of cervical cancer viruses, so the infection of other cervical cancer viruses cannot be prevented by domestic bivalent vaccination. Therefore, women should pay attention to sexual hygiene in general and have regular related gynecological checkups to effectively screen for cervical precancerous lesions at the time of early detection and early treatment.
