Expert: Women of school age who have been infected with HPV should also get HPV vaccine

　　China News Service, Shanghai, October 13 (Reporter Chen Jing) Cervical cancer is the most common gynecological malignant tumor. Early vaccination is very important to prevent cervical cancer.

The nine-valent HPV (human papillomavirus) vaccine has been expanded in age, and the applicable age has been extended from the original 16-26 years old to 9-45 years old, bringing the gospel to more women.

　　Professor Lu Yihan, Department of Epidemiology, School of Public Health, Fudan University, told reporters on the 13th that the age-expansion of the nine-valent HPV vaccine means that all women of school age can get more comprehensive protection.

At the same time, women can schedule vaccinations more comfortably.

It is reported that women who have not had sex with HPV vaccine can obtain the best preventive effect; women's immune function will decline with age, and the ability to clear new and previous infections will also decline, making persistent infections more likely.

This means that adult women are more dangerous after being infected with HPV, so HPV vaccination is very necessary for adult women.

　　Professor Lu Yihan told reporters that the age group of Chinese women infected with HPV virus presents a typical "double peak": the first peak age group is 17-24 years old; the other peak age group is 40-44 years old.

According to Professor Lu Yihan, in the past 20 years, the incidence and mortality of cervical cancer in China have been gradually increasing, which shows that the overall situation of cervical cancer prevention and treatment in China is still relatively severe.

Professor Duan Tao, an expert from the Shanghai First Maternity and Infant Health Hospital, said bluntly: "There are many HPV subtypes, including more than 200 types, which are divided into high-risk and low-risk types. The bivalent and quadrivalent HPV vaccines that have been promoted and used can be To prevent about 70% of cervical cancers, the nine-valent HPV vaccine can prevent 92% of cervical cancers."

　　Is it necessary to vaccinate women of school age who have been infected with HPV?

In this regard, Professor Duan Tao pointed out that it is necessary to be vaccinated.

There are many types of HPV, and infection is common.

Epidemiological surveys show that Chinese women are mainly infected with HPV by a single infection, and HPV vaccination can have a good protective effect on other types that have not yet been infected.

In the opinion of this expert, a woman who has been infected with HPV shows that her personal lifestyle or constitution makes her more susceptible, and it is more necessary to vaccinate herself to protect herself.

　　After receiving the HPV vaccine, I suddenly found out that I was pregnant. Will the vaccine have adverse effects on the fetus?

In this regard, Duan Tao pointed out that the HPV vaccine is safe during pregnancy.

At present, neither animal studies nor clinical practice have found any adverse effects of the HPV vaccine on the fetus.

The expert told the reporter: "If you find out you are pregnant during the vaccination process, then it will be too late for the next injection to wait until the child is born." If the nine-valent HPV vaccine is planned to be vaccinated after HPV vaccination, the vaccination can be started after at least 12 months, and the dose of vaccination is 3 doses.
