China News Service, Beijing, March 4 (Ren Jing) A few days ago, Xu Ping, a representative of the National People's Congress, suggested that the domestic bivalent HPV vaccine should be included in the immunization plan, which aroused widespread attention and became a hot search on Weibo.
In recent years, cervical cancer has the characteristics of rising incidence and younger incidence, which seriously threatens the life and health of women.
Inoculation of HPV vaccine is one of the effective measures to prevent cervical cancer. For this reason, many places in my country have deployed HPV vaccine for free vaccination of school-age women.

HPV vaccination for school-age women in many places
Recently, Hainan released the "2022 Hainan Province School-age Girls HPV Vaccination Project Implementation Plan", which plans to vaccinate 71,000 school-age girls with HPV vaccine in 2022.
The project implementation scope covers 18 cities and counties in Hainan Province and Yangpu.
Cervical cancer is a malignant tumor that seriously threatens women's health. Persistent infection of high-risk HPV is a necessary condition for the occurrence of cervical cancer. HPV vaccine can block the persistent infection of high-risk HPV, thereby effectively reducing the incidence of cervical cancer and precancerous lesions. Therefore, promotion of HPV vaccination among the appropriate age groups is an effective measure to prevent cervical cancer.
Previously, the National Health and Health Commission stated that my country will promote the pilot program and encourage regions with conditions to actively adopt various financing models to gradually carry out free HPV vaccination.
Since 2020, Ordos, Xiamen, Chengdu, Wuxi, Zhengzhou and other places have successively carried out or announced that free HPV vaccination will be carried out.
In addition, the Zhejiang Provincial Health and Health Commission also responded to questions from netizens a few days ago, saying that by promoting the implementation of comprehensive prevention and control strategies and measures in the pilot area (Yinzhou District), free HPV vaccination will be carried out for people of appropriate age.
With the gradual improvement of the level of economic and social development, it is not ruled out that free vaccination will be implemented throughout the province in the future.
Zhejiang Provincial Health and Health Commission responded to netizens' messages.
Cervical cancer incidence rises, younger trend is highlighted
Cervical cancer is a high-incidence malignant tumor in women, and it is recognized worldwide as the main "killer" that threatens women's health, ranking fourth in the global female cancer incidence and mortality.
In my country, cervical cancer is the second most common female malignant tumor.
According to the latest research report of the International Agency for Research on Cancer (IARC) in 2021, there will be about 110,000 new cases of cervical cancer in China in 2020. Among the cancers in women aged 15 to 44, the incidence of cervical cancer ranks third, accounting for about one third of Asia.
In recent years, cervical cancer has shown the characteristics of increasing incidence and younger onset. The youngest age of cervical cancer is as low as 15 years old, and the proportion of young cervical cancer patients younger than 35 years old is gradually increasing. Protecting young women from HPV infection is the key to reducing future fertility. The first key step in the occurrence of cervical cancer.
HPV vaccination is one of the effective measures to prevent cervical cancer.
The World Health Organization pointed out in the "Global Strategy to Accelerate Cervical Cancer Elimination" that there are three key measures to eliminate cervical cancer: vaccination, screening and treatment.
WHO proposes to achieve the goal of 90% of girls being vaccinated against HPV by the age of 15 by 2030.
According to my country's national conditions, the National Health and Health Commission recommends that the primary target group for vaccination is girls aged 13 to 15.

HPV vaccine should be given as early as possible
At present, there are four HPV vaccines approved for marketing in my country, and their safety and effectiveness have been verified.
Tan Xianjie, chief physician of the Department of Obstetrics and Gynecology of Peking Union Medical College Hospital, once introduced to the media, "The HPV vaccines that have been marketed around the world include bivalent, quadrivalent and 9-valent HPV vaccines, and 'price' represents the sub-categories of viruses covered by the vaccine. The higher the price, the greater the coverage of the virus. Wide." But at present, my country's nine-valent vaccine is "hard to get a shot".
Experts said that in the absence of appointments for high-priced vaccines, the public should also receive low-priced HPV vaccines in time to obtain the best protection.
If the main appeal is to prevent cervical cancer, the bivalent vaccine can basically meet the demand. "High-priced vaccines will play an icing on the cake for the prevention of cervical cancer, not a necessary option."
Li Xiaomao, director of the gynecology department of the Third Affiliated Hospital of Sun Yat-sen University, said that HPV is mainly transmitted through sex, so vaccination before the first sexual activity is the best recommended age.
However, after having sex, the chance of infection is greater.
HPV vaccine can effectively prevent cervical cancer, but the current vaccine resources are limited. In this case, it is recommended that HPV vaccination is best before the occurrence of first sexual intercourse to obtain the best preventive effect, and pre-adolescent girls are best vaccinated Prevention and control strategy, "early vaccination and early benefit".
Tan Xianjie also reminded that the protection rate of vaccines is not 100%, and regular screening after vaccination can prevent cervical cancer.
