The National Health Commission held a press conference on October 18 to introduce the situation of accelerating the elimination of cervical cancer. At the press conference, experts introduced that HPV vaccine can block the persistent infection of high-risk HPV, thereby effectively reducing the incidence of cervical cancer and precancerous lesions. However, the current HPV vaccine is a preventive vaccine, which has no therapeutic effect, and the vaccine does not contain all HPV types that can cause cervical cancer, so women still need to be screened for cervical cancer regularly after vaccination.
Wei Lihui, chief physician of the Department of Obstetrics and Gynecology of Peking University People's Hospital, said that a large number of clinical studies and real-world research data around the world show that the HPV vaccines currently on the market have very high protective efficiency. The HPV vaccines currently available in mainland China include bivalent, quadrivalent and 9-valent vaccines:
- The bivalent vaccine mainly prevents infection with HPV16 and 18, which are the two most important HPV strains that cause cervical cancer.
- In addition to HPV16 and 18, quadrivalent vaccine also prevents HPV6 and HPV11 infection, and can prevent cervical cancer and genital warts.
- On the basis of quadrivalent vaccine, the nine-valent vaccine has added the preventive and protective effect of HPV 31, 33, 45, 52 and 58, which can prevent the occurrence of cervical cancer, as well as genital warts, vaginal cancer, and anal cancer caused by related types of HPV infection.
According to the World Health Organization, any vaccine is effective in preventing cervical cancer, and HPV vaccination is best achieved by giving women who are not sexually active. In Sweden, 1.7 million women aged 10-30 years were followed up after vaccination in 2006-2017, and compared with unvaccinated women, women under 17 years of age had 88% fewer cervical cancers, and women aged 17-30 years had 53% fewer cervical cancers. It shows that HPV vaccination can effectively prevent cervical cancer.
In view of the good protective effect of the above three types of vaccines, women of appropriate age can choose to be vaccinated according to the varieties of HPV vaccines provided locally, as well as their financial ability and willingness, and early vaccination and early prevention.
