The supply of nine-valent vaccine has been in short supply since it came on the market. But experts advise,HPV vaccination should be as early as possible, blindly waiting for the nine-valent vaccine is a mistake.

The HPV vaccination rate among school-age girls in China is less than 1%

According to statistics, more than 80% of women have at least one HPV infection in their lifetime, and it is now clear that more than 99% of cervical cancers are associated with HPV persistent infection.HPV is spread mainly through direct contact and sexual activity.In addition to that,Early marriage, early childbearing, multiple sexual partners and smoking are all risk factors for cervical cancer.

The HPV vaccine has made cervical cancer the first cancer to be eliminated. Cervical cancer is the second largest female malignant tumor in China, with about 110,000 new cases every year.

The WHO recommends that the best age for HPV vaccination is between 9 and 14 years old, while the National Health Commission recommends that girls between 13 and 15 years old be the primary target group for HPV vaccination in accordance with China's national conditions. However, the HPV vaccination rate among school-age girls in China is less than 1%.

Zhao Fanghui, Director, Department of Epidemiology, Cancer Hospital, Chinese Academy of Medical Sciences:The incidence of cervical cancer is younger, and the average age of onset of cervical cancer may be more than 60 years old. At the moment it's 40, 50,There are a few cases where people in their 20s get it

Vaccination should be as early as possible

Blindly waiting for a nine-valent vaccine is not recommended

Currently, the approved HPV vaccines in China include two bivalent vaccines, one tetravalent vaccine and one nine-valent vaccine. The appropriate age for bivalent and quadrivalent vaccines is between 9 and 45 years, while the appropriate age for nine-valent vaccines is between 16 and 26 years. All four vaccines require three doses, which can be administered within six months.

Experts said that the high risk of cervical cancer caused by human papillomavirus is more clear 14, the most common is 16 and 18 two types, will cause about 80% of cervical cancer. The bivalent vaccine protects against HPV16 and 18; Quadrivalent is on the basis of bivalent, increased the prevention of HPV6 and 11 viruses. So experts suggest,Do not blindly wait for more HPV vaccine, but as early as possible to vaccinate, to be protected.

Qiao Youlin, Professor, School of Community Medicine and Public Health, Chinese Academy of Medical Sciences and Peking Union Medical CollegeThere are more than a dozen viruses that cause cervical cancer, but the main ones are type 16 and 18, which account for about 84.5% of cervical cancer cases, so bivalent vaccine is protected.
