With the birth of the HPV vaccine, cervical cancer has become the most promising cancer of human beings.

Do you know which one is suitable for you with a 2 -price, 4 price and 9 price HPV vaccine? Let ’s take a look at it today.

HPV and cervical cancer

HPV (human papilloma virus) is a DNA virus, which is currently found more than 200 species. It can be divided into high -risk (carcinogenic) and low -risk (non -carcinogenic) depending on the carcinogenicity.

HPV 16 and 18 are one of the two most common high -risk viruses. Low -risk HPV infections will not evolve into high -risk type (carcinogenic type). Generally, 80% to 90% of women will be infected with HPVs in their lives, and most of them can be removed automatically. A few high -risk HPV continuous infections may cause pre -cancer lesions. If the lesions are not treated, they may progress as cervical cancer. Studies found that 99.7%of cervical cancer is related to HPV infection.

The most effective measures for cervical cancer prevention and control are:

1. HPV vaccine vaccination

2. Regular cervical cancer screening

3. Early diagnosis and treatment of pre -cancer lesions

The combination of three measures can more effectively prevent and reduce the occurrence of cervical cancer.

HPV vaccination is used as a first -level prevention measure, and more and more people are accepted. According to the prevention of HPV types, there are currently three types of cervical cancer vaccines: 2, 4 and 9.

The prevention of different prices can be prevented as follows:

2 -valent HPV vaccine can prevent: type 16, 18 types; focusing on: binary vaccine can effectively prevent cervical cancer.

The 4 -valent HPV vaccine can prevent: type 16, type 18, 6, and 11, adding two low -risk types to prevent the occurrence of diseases such as condyloma acuminatum earlier.

The 9 -valent HPV vaccine can prevent: type 6, 11, 16, type 16, type 18, 31, 33, 45, 52, 58.

Some people think that there are fewer types of vaccine prevention, and the benefits of the two HPV viruses that are prevented are actually the big gangsters. Foreign studies have shown that cervical cancer caused by HPV 16 and 18 infections accounts for 70%of HPV infection related cervical cancer. A multi -center study in China shows that in China, about 85% of cervical squamous carcinoma is related to HPV 16 and 18 infections. Therefore, the two -valent vaccine can still prevent cervical cancer to a large extent, which is worthy of vaccination.

How to choose HPV vaccine

The three HPV vaccines in the Mainland my country are different. Please note:

2 price HPV vaccine: female 9 to 45 years old.

4 -price HPV vaccine: female 9 to 45 years old.

9 price HPV vaccine: 16 to 26 years old.

In addition to cervical cancer, you also want to prevent genital warts + economic conditions to be afforded: choose a 4 -valent HPV vaccine.

It can effectively prevent cervical cancer: 2 price HPV vaccines are more affordable.

Another problem with the HPV vaccine appointment is insufficient supply. But the good news is that the domestic 2 -price HPV vaccine has been approved to be listed, which relieves tension supply and demand.

In terms of prevention effectiveness, the analysis report of the third phase of the domestic 2 -valent vaccine period shows:

In terms of preventing HPV 16 and 18 and 18 continuous infections, the protection rate reaches 97.7%; the protection rate has reached 100%on the indicators of preventing HPV 16 and 18 related cancer lesions.

There is also an advantage of the 2 -price HPV vaccine: high cost performance. In the case where the protection rate is not much different, domestic pricing is cheaper.

Emphasizing the most important thing to prevent cervical cancer is to get HPV vaccines early! The best vaccine that can be hit as soon as possible, and the 2 price is also a good choice. If you have a vaccine demand, go to hospitals with conditions for vaccination as soon as possible.

Several problems about vaccination

1. Women who have sex/marry/have children, is it useful to vaccinate the HPV vaccine?

It is useful that sexual life does not mean that there is a HPV virus infection, and there is no inoculation effect without infection and no sexual life.

2. Can I infected HPV, can I vaccinate the HPV vaccine?

Yes, a person is unlikely to be infected with all HPV types included in the vaccine. Inoculation of HPV vaccine can prevent unintentional HPV types, and can also prevent the same HPV type infection again.

3. Can I vaccinate the HPV vaccine during menstrual period, pregnancy, and lactation?

Menstrual period: can be vaccinated normally.

Pregnancy: Avoid vaccination. Although the HPV vaccination has not been observed at present, there is a bad response to the mother and the child, but the data is limited. It is recommended that HPV vaccination should be avoided during pregnancy. If you find pregnancy after vaccination, you do not need to terminate your pregnancy. You only need to interrupt the vaccination.

Breastfeeding period: At present, no antibodies induced by vaccine will be secreted by breast milk, nor did it find the adverse effects on infants and young children after breastfeeding. Therefore, the HPV vaccine can be vaccinated during breastfeeding.

4. Do you treat HPV when you go to vaccine when HPV is positive? No, the role of HPV vaccine is prevention and does not have the treatment effect. And the current removal of HPV is basically relying on the mountain of our own immunity. There are currently no special effects drugs, which are specifically used to treat HPV viruses.

Therefore, there is no need to expect to treat your HPV by taking HPV vaccines, eat well, regularly work, strengthen exercise, and develop a healthy lifestyle.
