Nine -valent HPV vaccine "age expansion" expert: It is not recommended to blindly wait for seedlings or "replace" and "repeat"

A few days ago, the website of the State Drug Administration showed that Merida's nine -valent papilloma virus vaccine (brewing yeast) (hereinafter referred to as the nine -valent HPV vaccine) was expanded, and the applicable population was expanded to 9 to 45 years old. Earlier, the Nine-valent HPV vaccine was approved to be listed in China in 2018. The adaptation certificate is 16-26 years old. Once the news was released, it attracted great attention from all walks of life. Many women who had "unable to vaccire" had said that they could wait for it? At the same time, because the age range of vaccination is widened, can they still vaccinate the nine -valent vaccine for people who have previously vaccinated or four -valent vaccines? The reporter contacted the relevant experts.

As we all know, cervical cancer is one of the common gynecological malignant tumors, and the incidence and mortality ranks third in female tumors. Fortunately, cervical cancer is also the only cancer that can be prevented by vaccine. Scientific confirms that more than 99%of cervical cancer are caused by continuous HPV infection in high -risk HPV. HPV is mainly transmitted through sexual life or close contact. More than 80%of women have at least once HPV infections in their lives. Nearly 90%of HPV infections can be cleared naturally within 2 years. Patients with less than 1%of patients develop to cervical cancer before cervical cancer. Cervical and cervical cancer. It should be noted that high -risk HPV persistent infections are the necessary factor for the occurrence of high -level epithelial lesions and cancer in the inferior genital tract, and it has become a public health problem that seriously threatens women's health.

The HPV vaccine is mainly for preventive vaccines developed for HPV virus subtypes. Inoculation of HPV vaccine can prevent about 70-90%of cervical cancer. HPV two -valent, four -valent, and nine -valent vaccine represents the number of virus subtypes. The more the price, the more types of papilloma virus that can be prevented. The binary vaccine can prevent two subtype virus infections, HPV16 and 18, and the age limit of vaccination is 9-45 years. The quadrimal vaccine can be used to prevent HPV infection of type 6, 11, 16, and 18. The age; nine-valent vaccine can prevent HPV6, 11, 16, 18, 31, 33, 45, 52, 58 nine subtype virus infections, and the age of vaccination is 16-26 years old. Does the virus subtype type covering the vaccine represent the HPV vaccine for nine prices? Disease control experts said, of course not. Although the nine -valent HPV vaccine is currently the highest -price vaccine that can be used to protect HPV viruses on the market, it is more important than blindly waiting for nine valence. Related studies have shown that girls who have no sexual life and have not been infected with HPV can vaccinate the two -price vaccine to reach about 90%of the validity; women who have sexual life and even infected HPV, the effectiveness of the binary vaccine can still reach 70 %-80%. This shows that the two -price and quadriral HPV vaccine can also have a good prevention effect. It is not recommended to miss the best prevention timing in order to increase the scope of protection.

Many people have a cognitive misunderstanding of the nine -valent vaccine. They believe that the vaccination of the nine -valent vaccine will not suffer from disease caused by HPV? Experts have made rumors about this, saying that it is clear that no vaccine can play a 100%protection effect. The nine -valent HPV vaccine increases the proportion of cervical cancer from 70%to 90%, which can only reduce the probability of cancer and does not cover all high -risk HPV types. Therefore, the nine -valent HPV vaccine cannot prevent 100%prevent all HPV infection caused by HPV. Or disease, cervical cancer screening after vaccination should be carried out regularly. For people who have been vaccinated or have not yet completed the full vaccination, people who have not yet completed the full -process HPV vaccine, let alone see the nine -valent vaccine "heart movement" and "repeat". Women only need to complete one type of cervical cancer -related vaccine in their lives. "Make up" and "repeat" will not benefit. It may also add adverse reaction risk because of the different vaccine manufacturers and preparation technology.

At the same time, the reporter also learned that the new age of the Nine -Valental HPV vaccine has just been approved. At present, the city has not received relevant notices and will still be vaccinated at the original age of vaccination.
