HPV vaccine should be given as early as 9 to 14 years old is the best age for vaccination
Cervical cancer is one of the common gynecological cancers and one of the few cancers that can be prevented by vaccines.
Experts have suggested that the incidence of cervical cancer in my country has a trend of younger age, and women who are currently willing to receive HPV (human papillomavirus) vaccine are generally older. It is recommended that more attention be paid to the vaccination of young women.
Bi Hui, chief physician of the Department of Obstetrics and Gynecology of Peking University First Hospital, found that in the gynecological clinic of the hospital, most of the women who came to receive HPV vaccination were women over the age of 25. Adolescents between the ages of 13 and 18 could only see it occasionally. Parents bring their daughters to consult about vaccination.
Bi Hui said: "In my country, the current bivalent and quadrivalent HPV vaccine is approved for women aged 9 to 45, and the nine-valent HPV vaccine is suitable for women aged 16 to 26. The HPV vaccine is most effective before starting sexual life. Well, adolescents should be the key population. The best age for vaccination recommended by the World Health Organization is 9 to 14 years old. my country's guidelines recommend 13 to 15 years of age as the key population."
According to reports, viruses such as HPV are divided into multiple subtypes, which can be classified into high-risk and low-risk types.
The high-risk type can cause cervical cancer, anal cancer, oropharyngeal cancer, and the low-risk type can cause flat warts, common warts, and condyloma acuminatum on the skin.
The main route of transmission of high-risk HPV is sexual transmission.
Bi Hui introduced that in recent years, a study of more than 130,000 gynecological outpatients in 8 tertiary hospitals across the country showed that the infection rate of high-risk HPV is nearly one-fifth.
Studies have shown that due to the different numbers of preventable virus subtypes, bivalent and quadrivalent HPV vaccines can prevent about 70% of cervical cancers, and nine-valent vaccines can prevent about 90% of cervical cancers.
Experts emphasize that vaccination can greatly reduce the risk of cervical cancer.
