Definition and role of the nine-price vaccine
Coverage of virus 1.
Of the nine types of hpv virus targeted by the ninth-price vaccine, type 16/18 is responsible for approximately 70 per cent of cervical cancer, with other high-risk types (e. G., 52/58) having higher infection rates among the asian population. In addition, type 6/11 is mainly abdominal (spicy wetting)。
Disease prevention type 2.
In addition to cervical cancer, genital, vaginal, anal and some oral cancers can be prevented, and male vaccinations reduce the risk of genitals and infections。
Ii. Applicable population and vaccination procedures
Inoculation age 1.
The best vaccination time is before the first sexual act, but even if there is sexual activity or an infection with hpv, vaccination is recommended to prevent other infected subtypes of the virus. The age of vaccination is currently 9-45 years for women and 9-26 years for men in most regions。
Vaccination period and cycle.
Usually three doses are required: one in 0, 2 and six months. If the delay is due to exceptional reasons and no new start is required, the remaining agent should be filled。
Iii. Caution and common doubts
Vaccine protection effectiveness 1.
Clinical studies have shown that the prevention of cervical cancer is close to 90 per cent effective for nine-valent vaccines and over 95 per cent for sharp hyenas. However, vaccines cannot eliminate existing hpv infections or replace cervical cancer screening。
Vaccination is forbidden.
Sensitization of vaccine components, pregnancy of women and acute disease are suspended. Breast-feeding women are required to consult a doctor。
Iv. Distinction from other hpv vaccines
Bivalent vaccine 1.
Coverage is limited to type 16/18 hpv, with a focus on the prevention of cervical cancer, which is applicable at a wider age (9-45) and at lower prices。
4-valent vaccine 2.
Coverage of type 6/11/16/18 prevents cervical cancer and genital acupuncture but lacks protection against the high prevalence of type 52/58 in asia。
Option 3.
The coverage of the ninth-price vaccine is the widest, but the supply is tight and high; if the ninth-price vaccine is not available, the second- or fourth-prices will provide basic protection。
V. Social implications and health recommendations
The hpv vaccine is a central tool for cervical cancer prevention, and the world health organization (who) has recommended that hpv vaccines be included in national immunization plans. Vaccination + regular cervical cancer screening (e. G. Tct, hpv) is a dual safeguard strategy. The public needs to make an appointment for vaccination through a formal institution to avoid waiting blindly for high prices to miss the best protection opportunity。
Universal access to the nine-valent vaccine is critical to the global goal of eliminating cervical cancer, but needs to be combined with rational choices of individual conditions (e. G. Age, economy, vaccine availability), while raising awareness of hpv transmission pathways (sexual contact, skin mucous contact) and reducing the risk of infection across the board。
