Why do women need the understanding of cervical cancer vaccine?  Women should learn about the knowledge and both cervical cancer and related vaccines as early as possible in order to take preventive measures.


What is HPV (Human papillomavirus)?

A DNA virus belonging to the papillomavirus genus of the papillomavirus family. This type of virus infects the epidermis and mucosal tissues of the human body.

At present, about 170 types of HPV have been identified. Genital skin contact is generally considered to be a mode of transmission. Human papilloma virus is transmitted through sexual activity, and genital skin contact is also generally considered to be a mode of transmission.

HPV virus can also enter the human body through wounds or micro-abrasions. To give a simple example, if the hotel towels are not disinfected in place, they may be replaced with HPV if they touch a wound on the body during use.

The virus is all around us, so it is very important to get HPV vaccine.

 

 


Statistics of cancer patients

According to the data in 2018, there are 18,000 new cases of various cancers (not all caused by HPV virus, but almost all cervical cancers are caused by HPV virus). There are 18,000 uterine cancer, 49,000 anal cancer, 44,000 vulvar cancer, and 570,000. Cervical cancer (including more than 100,000 cases in China, and more than 300,000 deaths), other low-risk virus infections are not well counted, and condyloma acuminatum refers to the previous data about tens of millions per year

 

Is there a high chance of being infected with the virus in a person’s life?

Men and women who have sex have a lifetime risk of being infected with the virus as high as 85%-90% (US research), while the high-risk virus detection rate for women in some countries is 14.8%, but this data is in the current progressive tense rather than the past perfect tense.

 

Are condoms useful?

It can reduce the risk of transmission, but it cannot be completely avoided. There is also the possibility of transmission from lower body contact.

What are the high risk factors for cervical cancer?

High pregnancies, smoking, long-term oral contraceptives, immunosuppression, premature sex, a large number of sexual partners, exposure to diethylstilbestrol.

 

Receiving HPV vaccine

 

Is HPV vaccination required for non-contact sex?

Fight early and prevent! The best age for vaccination recommended by the World Health Organization is 9 to 14 years old. some countries’s guidelines recommend 13 to 15 years of age as the key population. According to reports, HPV is divided into multiple subtypes, which can be classified into high-risk and low-risk types. The high-risk type can cause cervical cancer, anal cancer, oropharyngeal cancer, and the low-risk type can cause skin problems. Flat warts, common warts, and condyloma acuminatum.

Why do women need the understanding of cervical cancer vaccine?  Women should learn about the knowledge and both cervical cancer and related vaccines as early as possible in order to take preventive measures.

 

 

Existing vaccines and effects

  • 2-valent: 2 kinds of HPV virus cannot survive in the human body. It is used to prevent HPV-16 and HPV-18, which are the HPV viruses that can cause cervical cancer.
  • 4-valent: HPV-11 and HPV-4 for the prevention of genital warts and skin warts, as well as the two mentioned in the previous two prices
  • 9-valent: In addition to the additional species in the previous 4, it can prevent cervical cancer, vaginal cancer, cervical lesions, reproductive lesions and anal cancer, etc.

 

 

What are the advantages and disadvantages of different vaccines?

The advantage of the 2 price is that the antibody titer is higher; the advantage of the 4 price is to prevent 2 more low-risk viruses than the 2 price, specifically it can prevent 90% of condyloma acuminatum; the advantage of the 9 price is the wide coverage. A total of 7 high-risk viruses and 2 low-risk viruses were prevented.

 

Which one should the individual choose first?

Based on current knowledge, I personally definitely prefer 9-valent vaccines, followed by 4 or 2 prices, and choose 4 or 2 prices, depending on whether you want to prevent more types of infections. I personally prefer to have the right ones. More types of protection.

 

If I have been infected with the virus, is it still useful to be vaccinated?

Unless you are infected with all the types covered by the vaccine, there will be some effect anyway. In addition, the level of antibodies produced by vaccination is much higher than that of natural infections. Vaccination can reduce the risk of recurrence.
