Free vaccination of HPV vaccine in some areas of China is the best age for vaccination.

CCTV News:The World Health Organization has designated the last week of April as "World Immunization Week", and this year’s theme is "Vaccine makes us closer". The reporter learned from National Health Commission yesterday (28th) that in order to prevent cervical cancer, China has started the pilot human papillomavirus vaccine, that is, the free vaccination of HPV vaccine in some areas.

At the National People’s Congress in 2020, many deputies called for free HPV vaccination for school-age girls in China as soon as possible. In February this year, National Health Commission publicly replied that it would promote the pilot project first, encourage qualified areas to actively adopt various financing models, and gradually carry out free HPV vaccination. Just a few days ago, Erdos, Inner Mongolia, launched the city-wide HPV vaccine free vaccination project, with the city’s 13-mdash; 18-year-old women can get three shots of HPV vaccine free of charge at designated medical institutions only by paying the vaccination service fee. Guangdong province also said recently that it is actively studying the free vaccination of HPV vaccine for school-age girls.

Zhao Fanghui, Director of Epidemiology Department of Cancer Hospital of China Academy of Medical Sciences:The first way is to enhance the public’s correct scientific understanding of HPV vaccine and cervical cancer and vaccinate as soon as possible; The second way is to promote from the national or government level, and bring HPV vaccine into the immunization program as soon as possible. I think this is also the best way to improve the coverage of HPV vaccination.

The vaccination of girls aged 9 to 14 in China is less than 1%

Last November, led by the World Health Organization, 194 countries around the world, including China, made the first commitment to eliminate cervical cancer by 2030. At present, cervical cancer is the second largest female malignant tumor in China, and the number of new cases in China is around 110,000 every year. In the past two decades, the incidence and mortality have been increasing year by year, and they are getting younger.

Zhao Fanghui, Director of Epidemiology Department of Cancer Hospital of China Academy of Medical Sciences:We found that this younger age is the average in the past. The average onset of cervical cancer may be in the 60 s, but now it can reach the age of 40 or 50. Of course, some patients are younger, and they will also suffer from it in their twenties. From our point of view, it will be about 5 years earlier than 20 years ago.

HPV vaccination is one of the most critical measures to prevent cervical cancer, and another key measure is cervical cancer screening. With the birth of HPV vaccine, cervical cancer is expected to become the first malignant tumor that can be completely eliminated. The standard recommended by WHO is that 90% of girls should complete HPV vaccination before the age of 15, but many countries, including China, are far from meeting this standard.

Bivalent and tetravalent vaccines have provided most protection.

The data show that more than 99% of cervical cancer is related to human papillomavirus, that is, HPV persistent infection. After the whole process of HPV vaccination, it can provide enough protection for women, and there is no doubt about the effectiveness and safety of the vaccine. At present, there are four kinds of HPV vaccines approved for marketing in China. How to choose and fight?

The four approved HPV vaccines include two bivalent vaccines, a tetravalent vaccine and a nine-valent vaccine. The valence mentioned here refers to the type of virus, so simply speaking, the multivalent vaccine is how many types of HPV virus can be prevented. The suitable age for bivalent and tetravalent vaccines is 9-mdash; 45 years old, the suitable age for nine-valent vaccine is 16-mdash; 26 years old, all four vaccines need three shots. Since the price represents the type of virus, is it necessary to vaccinate high-priced vaccines to play a better protective role?

Zhao Fanghui, Director of Epidemiology Department of Cancer Hospital of China Academy of Medical Sciences:There are fourteen types of high-risk human papillomavirus that cause cervical cancer, among which the most common types are 16 and 18, which will cause more than 80% of cervical cancer. Therefore, bivalent and tetravalent vaccines cover 16 and 18 types, and the nine-valent vaccine has five additional types besides the 16 and 18 most important types. Two-valence, four-valence, and nine-valence may sound very different in numbers, but in fact the difference is 10%— Between 15%, bivalent inoculation can avoid cervical cancer with high probability.

The incidence of malignant tumor increases and the mortality decreases.

Yesterday (28th), the Beijing Cancer Prevention and Research Office officially released the Annual Report on Cancer Registration in Beijing in 2020. This is the first time that Beijing has publicly released the cancer monitoring data of its residents in the form of an annual report.

The Annual Report summarizes the 2017 tumor registration data submitted by 168 secondary and above medical institutions in the city, and analyzes the incidence and death of 23 common malignant tumors, the different characteristics of male and female incidence spectra, and regional differences. According to the Annual Report, there were 50,070 new cases of malignant tumor among registered residents in Beijing in 2017, with an overall incidence rate of 367.88/100,000, with an average annual increase of 2.11% in the past 10 years. The mortality rate is 191.38/100,000, with an average annual decrease of 1.06% in 10 years.

Ji Jiafu, Dean of Peking University Cancer Hospital:Although the incidence rate has increased, the mortality rate has decreased. First, it is related to the corresponding and relevant policies issued by the government, encouraging early screening; The second is that with the improvement of education level, people’s attention and awareness of their own health are increasing. Therefore, the tumor was discovered earlier. Although it was discovered, the cure rate was relatively high and the mortality rate decreased.

The data show that the top five diseases in men are lung cancer, colorectal cancer, liver cancer, gastric cancer and prostate cancer, and the top five diseases in women are breast cancer, lung cancer, thyroid cancer, colorectal cancer and uterine body cancer.
